This report reflects the results and activities of Stage 1 planning. PURPOSE AND AUTHORITY There are three primary purposes of this study. Those purposes are (1) bank stabilization on the Kansas River and Tributaries in Kansas, (2) municipal and industrial water supply in the Kansas and Osage River basins in Kansas,and(3)control of mineral intrusion on the Kansas River and Tributaries in Kansas. This study is being conducted in response to five congressional resolutions. The five resolutions read in part as follows: 1. Senate Committee on Public Works, Resolution dated 17 October 1973, to determine whether channel improvements, bank and channel stabilization, and related improvements are desirable on the Kansas River and Tributaries in Kansas, particularly downstream from existing reservoirs. 2. House Committee on Public Works, Resolution dated 11 April 1974, identical to the Senate reso- lution above. 3. Senate Committee on Public Works, Resolution dated 2 February 1977, to determine whether modifications to Kansas River and Tributary reports are advisable, including consideration of improve- ments within Kansas for supply, conveyance, and distribution of water to areas of need and for the control of mineral pollutants in streams from natural sources. 4. Senate Committee on Public Works, Resolution dated 2 February 1977, to determine whether modifications to Osage River and Tributaries reports are advisable, including consideration of improve- ments in Kansas for supply, conveyance, and distribution of water to areas of need. 5. House Committee on Public Works and Transportation, Resolution dated 10 May 1977, identical to Senate Resolutions 3 and 4 above. SCOPE OF THE STUDY The study will be of survey scope. This reconnaissance report represents studies through the first of three study stages. The study area can be generally described as the northeast quarter of the state of Kansas. More specifically, the study area is somewhat different for each of the three primary pur- poses, as shown on Plate A-1. For bank erosion, the study area is the flood plain of the Kansas River and principal tributaries upstream to the first existing Federal lake or active authorized lake site. Prin- cipal tributaries include the Wakarusa River, Delaware River, Vermillion Creek, Big Blue River, Repub- lican River, Solomon River, Saline River, and Smoky Hill River. This area includes 18 counties. For • water supply, the study area includes 36 counties in northeastern Kansas, plus Sedgwick and Harvey Counties in south central Kansas. For mineral intrusion control, the study area is that 24-county area in the Kansas River basin where geologic formations containing salt and gypsum are exposed or near the ground surface, and areas where mineral intrusion affects the quality of surface waters. STUDY PARTICIPANTS AND COORDINATION A major public involvement effort has been initiated to inform the public and to receive public views and concerns. Many activities have been used through the first study stage to encourage citizen participation and to promote a high level of Federal and State agency participation. Activities include public meetings and workshops, a Federal-State Coordinating Committee, a brochure, fact sheets, a • news release and magazine article, and on-site visits with landowners in the study area.

One is the report of the Chief of Engineers on the Kansas River and Tributaries, Kansas, Nebraska, and Colorado, pub- lished as Senate Document Number 122, 87th Congress, Second Session. The second report under re- view is the report of the Chief of Engineers on the Osage River and Tributaries, Missouri, and Kansas, , published as House Document Number 549, 81st Congress, Second Session. The following paragraphs summarize those and other pertinent reports of the Corps of Engineers and other agencies. Reports are authored by the Corps unless otherwise noted. HOUSE DOCUMENT NO. 73-195(1934). This is the "308 Report" on the Kansas River basin. It described Kansas River flooding at Kansas City and presented an adopted plan for improvement on the lower Kansas River which consisted of ' channel enlargement, levee raises, and bridge alterations. HOUSE DOCUMENT NO. 78-475(1944). This report presented a comprehensive plan for a system of Missouri River basin lakes and levees. The plan was coordinated with a similar U.S. Bureau of Reclamation report described in Senate Docu- ment No. 78-191 (1944). The authorized plan, often referred to as the "Pick-Sloan" plan, included a number of Kansas River basin projects, principally for flood control and irrigation. HOUSE DOCUMENT NO. 81-549(1950) This report on the Osage River basin in Missouri and Kansas resulted in the authorization of nine lakes and two local protection projects. Five of the nine lakes were in Kansas, and of those lakes two are now in operation and a third is under construction. HOUSE DOCUMENT NO. 81-642(1950) This report on the Kansas River and tributaries recommended Milford and Perry Lakes, both now in operation. It also recommended several local protection projects. KANSAS RIVER BASIN (1956) This Bureau of Reclamation report summarized existing and potential water resource development information for the basin, particularly concerning irrigation. SENATE DOCUMENT NO. 87-122(1962) This report on the Kansas River and tributaries recommended additional tributary lakes, of which three were authorized. The report also called for increased levee and floodwall protection on the lower 10 miles of the Kansas River. A plan for stabilizing the banks of the Kansas River from Junction City to • Kansas City was found to be economically infeasible. A-3 National Economic Development (NED) objective-to increase the nation's output of goods and services and improve national economic efficiency. Environmental Quality (EQ) Objective—to enhance the quality of the environment by the manage- ment, conservation, preservation, creation, restoration, or improvement of the quality of natural and • cultural resources and ecological systems. • A-5 iI • • j Solomon Con�ordlo Goodland�- .• R • Manhatloniopeko \ ,� ��=Ha '--j-Salina R ansas �36Z,rI �` rea City ...• a •Garden City • Ha• i ° Yates enl • ooe a City WI m+a PHILLIPS _ SMITH JEWEL Y Pittsburg .

During the • early development of Kansas, the river valleys provided the most favorable corridors for railroads and later for highways. Major losses from erosion have occurred to cropland and to developments of man in the valleys. • EXISTING CONDITIONS Bank erosion is a natural process which has been occurring on the Kansas River and tributaries for thousands of years. The basic physical conditions of flowing water and erodible soil remain the same but the process may now be affected by human activities to the extent that it can no longer be con- sidered natural. Human activities which may impact on the natural process are summarized in Table B-1. TABLE B-1 • HUMAN ACTIVITIES IN THE STUDY AREA WHICH MAY AFFECT BANK EROSION Type Occurrence Till Farming in Valleys Land clearing for till farming in the valleys was largely accomplished between 1870 and 1930. Riparian Vegetation Changes The tree-lined river corridor has been maintained where possible in most areas. Urbanization in Valleys Thirty-eight towns were populated in the.early to late 1800's. Significant urban growth occurred (1900-present) in Salina, Junction City, Manhattan, Topeka, Lawrence, and Kansas City. Bank Stabilization Works Predominant since 1940's and 1950's. See Table B-3. Large Lakes Seven large lakes have been constructed starting with Kanopolis Lake(1948)and including, most recently. Clinton Lake(1979). , Small Lakes and Ponds Thousands of small lakes and ponds, many constructed after the 1930's drought, and many more after the 1950's drought. Dredging in River Commercial dredging for construction materials developed largely in the 1950's and reached annual volumes of 2-2.8 million tons in the 1970's. Occurs mostly on the Kansas River. • Railroads and Highways Railroad development began in 1860's while significant highway development did not occur until after 1940. • Rights-of-Way and Bridges Channel Modifications Natural cut-offs have been much more significant than man-made ones. Seven major flood-related channel changes have occurred on the Kansas River, and many more on the tributaries. The only major man-made channel modification in the study area is the Corps built Smoky Hill channel at Salina(late 1950's). Upland Soil Conservation Practices These practices began to be used after 1930. Valleyland Irrigation • Significant valley land irrigation has occurred only after 1950. • Channel Migration. Bank erosion is accompanied, over time, by movement or migration of the river channel. A major task of this study was to document the channel migration from the time of the earliest reliable maps of the late 1800's to the present. That history is discussed in Appendix 2, and is recorded on maps in Appendix 3 to this report. This history of channel migration should provide some basis for , determining how human activities have affected bank erosion. An important question concerning existing conditions is whether bank erosion is more severe now than it was 10, 20, or 50 years ago. The channel migration history provides the key to answering such questions, and can also provide insight for prediction of future migration. As an early study effort, Kansas River was divided into reaches of contrasting levels of activity for approximately the past 100 years of record. Categories of activity were "active," "stable," and "minor." This 100 year activity map, (Plate B-1), clearly shows an alternation of active and stable reaches. In addition, the reaches displaying a high degree of activity in the past ten years show little correlation to • reaches that were highly active over the 100 year span. Some of the presently active portions are indeed located within reaches that also underwent long term activity, but others lie along segments that have B-1 • . il The summary maps of recent channel migration of the three major tributaries clearly demonstrate a remarkable stability. Channel movement since 1947 involves areas that are small. The Smoky Hill I River shows some natural and artificial cutoff, but little lateral movement. The Saline River shows little movement, and the Solomon River shows almost no movement. Comparison of the maps of recent • (since 1947)channel migration with maps of area of channel migration (since 1850) gives the impression I that channel activity has recently decreased on the principal tributaries. Existing Bank Protection. Bank stabilization work was first undertaken at about the turn of the century. However, little effective work was accomplished until about 1940. Considerable stabilization work has been performed since 1940, and that work is summarized in Table B-3 for the Kansas River I from Junction City to the mouth. The table includes information on location, length, type, age, and probable sponsor or owner of existing stabilization works. Relative to the Kansas River, much less bank stabilization work has been undertaken on the tribu- I taries. Generally, work has occurred only where adjacent development was threatened such as at a bridge crossing or where railroad tracks parallel the river.

Rates of erosion would depend upon the occurrence of floods, droughts, and other unpredictable natural events, as well as the continued human activities along the river. Private interests and county or drainage districts would continue to apply bank stabilization meas- ures in several areas, but not on a coordinated basis. Railroad companies also would continue to apply bank stabilization measures as railroad tracks become threatened by continuing erosion. I Six reaches have been identified on the Kansas River as being areas of the most severe present and predicted future bank erosion. These worst areas total 50 miles.of river. Assuming previous rates of erosion at the sites would continue, it is estimated that about 4,200 acres of valuable agricultural farmland and riparian woodlands will be lost by the year 2030. Significant amounts of bottomlands i should also be realized by stream meandering and natural sediment accretions on opposite banks. Erosion rates at these sites are highly variable within the specified reaches, ranging from 10 to 100 feet • per year as the 25-year average. These areas of severe erosion seem to be located in isolated locations i from one to three miles in length. Very rapid episodes of erosion have been recorded. At Eudora Bend • an extreme burst of migration has been taking place for the past few years. At one point the river has cut about 250 feet within three years, with 150 feet of the erosion occurring in one year. This 150 foot • movement represents roughly three quarters of an acre loss for every 200 feet of eroding bankline, or about 18 acres loss per mile of river bank. This, however, is an extreme case. An average erosion rate of 20 feet per year represents roughly an annual loss of 2.6 acres per mile of eroding bankline. The following table lists the Kansas River severe erosion study areas, average annual erosion rates for each • site, and the projected acreage losses to the year 2030. It also lists annual point erosion rates and • acreage losses for the most severely eroding bend in each area. i PROBLEMS, NEEDS, AND OPPORTUNITIES - The occurrence of bank erosion along the Kansas River and tributaries causes economic losses in several forms. These losses were expressed by persons attending public meetings as follows: • Farmland, predominantly cropland, is lost. • Property values on riparian cropland are reduced. 1• • Local tax bases are reduced. all • Roads, highways, railroads, and bridges are threatened, and must be protected or lost. B-5 2. Provide increased recreational opportunities along the Kansas River and its tributaries in the study area, particularly along the Kansas River below Lawrence. 3. Enhance the environmental attributes of the Kansas River and its tributaries in the study area, as related to solutions to the bank erosion problem. • FORMULATION OF PRELIMINARY PLANS ALTERNATIVE MANAGEMENT MEASURES A wide range of structural and nonstructural measures were considered for possible use in plans to reduce erosion. They include the following: • Stone dikes • Vane dikes • Stone fill revetment • Tree retards j • Toe protection • Car bodies • Windrow revetment • Vegetative stabilization • Hardpoints • Easements(several purposes) • Tire revetment • Stream flow regulation Each of the above measures id discussed in the following paragraphs. Stone Dikes(Figure B-1). Stone dikes are stabilization structures constructed from the bank of the river at an angle to the current. The structures are used to divert the current or refine the channel alinement. The amount of accretion behind the dikes can be controlled by placement of notches. These massive structures do not blend into the natural environment. Their use would be limited to the most severely eroding areas. `� 1441' i 1 II III��II(►i�IJlll� 611114 ���il�,,,;dl �Nl,,111114.1 C11":;l2I-N\-\ • FIGURE B-1 STONE DIKES Stone Fill Revetment (Figure B-2). Stone fill revetment is basically a stone fill dike that is placed in the stream parallel to the eroding bank. The structures protect the bank from all but high flows and due to their massive nature tend to hold their alignment. Because these structures are parallel to the bank they do not acrete land as dikes do. Their use is generally limited to where toe protection would not provide adequate protection. . 1 B-7 ii• • FIGURE B-4 • WINDROW REVETMENT Hardpoints(Figure B-5). Hardpoints consist of sections of stone spaced intermittently along an erod- ing bankline. The structures protrude only short distances into the river channel and can be supple- mented with a root section extending landward to preclude flanking should excessive erosion persist. The majority of the structure cannot be seen as it consists of underwater placement of rock. The aquat- ic portion of the structure would improve habitat diversity, however, the above water portion would be less desirable from an esthetic viewpoint. The above water portion can, however, be covered with soil and plantings to improve the esthetic appearance. • t • . � FIGURE B-5 HARDPOINTS Tire Revetment(Figure B-6). Used automobile tires have been utilized successfully in some areas to g ure B-6) stabilize eroding banks. The tires are banded together to make a protective mat that is secured to deadman anchors. The tires not only protect the streambank from flowing water, but after they collect silt and become permanently embedded, the tires protect the roots of young trees planted to restore a vegetative cover. Although somewhat subject to early damages, this measure would be considered a li valuable assist to any vegetation establishment plan. B-9 ' NMTP .I • Vii`'•�. Lk . FIGURE B-8 • TREE RETARDS Car Bodies (Figure B-9). Car bodies, when stripped of contaminates such as oil, grease and uphol- stery, can be utilized for constructing toe protection and bank paving. The car bodies should be placed in an orderly fashion, cabled together, and securely anchored. The car bodies, while unsightly at first, will collect silt and encourage revegetation of the eroded bank. This measure although still allowed by law is not considered desirable from an esthetic viewpoint. This measure, therefore, was not consid- ered further.

Vegetative stabilization consists of planting a corridor of trees along the riverbanks in those locations where trees have been removed or lost from erosion. A passive method would be represented by general agreements between private landowners, conservation districts, and levee-drainage district. To complement any "corridor preservation" agreements, an active method of stabilization such as "plantings" could be initiated to fill in the gaps in the vegetation corridor. Plant- ings, however, would probably have to be done in combination with some type of light structural pro- tection method in order to insure establishment. Without a structural assist, vegatative stabilization is not a proven method, and probably could not be considered a long-term measure. Easements. Easements could be purchased by governmental interests for specific limited pur- . poses. Under this arrangement, the landowner retains ownership and thus may continue to farm or conduct other operations on the major portion of the ownership. There are several possible purposes • for which easements could be purchased.Two such purposes are: B-11 I� i K Site l Eudora-Fall Leaf-Schaake Bend 2 Lawrence-Lakeview 3 Tri-County-St.Mary's 4 Belvue 5 Wabaunsee 6 Swamp Angel • Monhatton� id _ t _ ' f - Kansas. • Bonner Springs City - Junction City • ` De Soto �,7 Eudora 10 51 • River. The plan, identified as Plan D, could include designation of a 57-mile segment of the lower Kansas River as a National Recreation River. The plan was prepared by the Mid-Continent Region, Heritage Conservation and Recreation Service. A complete copy of the report by that office is included in Appendix 7, Recreation and Natural Resources. The plan is shown on Plates B-23 through B-42. • Combination Plans. Three combinations of structural and nonstructural measures were consid- ered. Plan E would combine vegetative management.with light structural measures. Measures such as hardpoints, toe protection, or tire revetments would assist the establishment of permanent vegetation in eroding areas. Plan F and Plan G would combine the recreation river concept with vegetative management and structural measures. For Plan F, the light structural measures would be included and for Plan G the medium structural measures would apply. No plates are included for the three combination plans because they simply include the same types of measures shown in Plans A through D. No Action. This alternative would provide no Federal action toward reducing streambank erosion. Other organizations or individuals would continue taking action by applying treatments to localized problems, but without a particular overall plan. Bank erosion would continue more or less as it has for the past 25 to 50 years. Other Options. Streamflow regulation was noted as a possible measure but was not included in any of the preliminary plans. It was not included because it has not yet been determined in what way regu- lation would affect rates of erosion. If regulation is found to have a significant effect it would be placed in the nonstructural plan category, and it could be added to any of the other plans. Studies are present- ly underway to determine if modification of flood flow release schedules at existing lakes can have a significant effect on bank erosion rates. ASSESSMENT AND EVALUATION This section provides a preliminary assessment of the economic and environmental aspects of the conceptual plans. The assessment relates to the six severe erosion areas on the Kansas River. Addi- tional economic data is provided in Appendix 10, and additional environmental information can be found in Appendix 7. PLAN A - MEDIUM STRUCTURAL This plan is composed largely of medium weight structural measures. Its primary structural com- ponents are toe protection, hardpoints, and windrow revetment with a more limited use of massive stone fill dikes and massive stone fill revetments. Plan A would provide protection to approximately 50 miles of severely eroding banks. Although this plan is of medium weight, the measures included are to be considered adequate to hold existing bank lines. Economic Analysis. Plan A meets one of the major objectives of the study in that it reduces econo- mic losses along the Kansas River. Economic feasibility was determined by comparing average annual project construction costs with average annual benefits. The most significant impact of Plan A would be that of erosion damage reduction. Projected lost land damages from channel migration at the six study sites were estimated to be 2,635 cropland acres and 1,535 non-cropland acres over the 50 years of 1980-2030. Average annual benefits are derived from expected losses in productive crop values or other costs which would be incurred in the absence of a comprehensive bank stabilization plan. All of these losses would be eliminated by a bank stabilization project. Losses include: • Losses of agricultural land and productivity • Losses of taxes on agricultural land • Cost to protect railroad tracks • Cost to protect highway bridges • Loss of miscellaneous buildings • • Cost to relocate roads • B-14 • • A detailed breakdown of annual losses for the six severe erosion areas is presented in Appendix 10. A summary of preliminary costs and benefits for the six areas is provided in Table B-5.

Sensitivity analysis was performed using the current cropping pattern and maximum projected yield, and also using only the crops with the highest current productive value. This sensitivity increased B/C ratios from 10% to 90%, however, none were raised above unity. None of the medium • structural plans for the six study areas would have benefits exceeding costs. Therefore, Plan A could not be recommended for further study. Environmental Assessment. From the aquatic environmental viewpoint, it has been found that toe protection hard point and wind row revetment would provide a more diverse aquatic substratum. This would increase invertebrate colonization and fish cover, both of which are limited in the mainstream Kansas River. Dikes and hardpoint structures may allow the formation of scour holes at their tips re- sulting in deep water habitats for fish, and flow patterns behind these structures may create shallow backwater areas where aquatic communities can develop until prohibitive siltation occurs. Structures would also increase fisherman access to the river. Adverse aquatic impacts are also possible. While bank stabilization structures may result in in- creases in streambank vegetation and wildlife habitat due to accretion of sediment and bank protec- tion, significant losses of water surface area can occur, especially when dikes are used. Notches placed in dikes can help relieve this problem. Stone fill revetments and dikes can also increase current veloci- ties and decrease channel capacities. From a terrestrial standpoint, Plan A would permit preservation of 1,535 acres of non-cropland area which presently provides substantial wildlife habitat. However, implementation of the plan would • require disturbance of a portion (less than 10 percent)of that area including riparian timberland. Other adverse impacts would be increased siltation during construction and negative visual impact. PLAN B - LIGHT STRUCTURAL This plan consists of using only hardpoints as a means of protection at the six severe erosion sites. Hardpoints would be spaced at 600 foot intervals to provide protection to approximately 50 miles of eroding banks. This plan is to be considered the minimum structural effort which would be expected to hold existing bank lines. At the most rapidly migrating bends, there is a possibility that additional work may be required if hardpoints do not hold. Economic Analysis. This plan would protect the same area as Plan A, and would provide identical benefits. The major difference in the economic value of the two plans is that the heavier measures in Plan A provide greater assurance against high future maintenance and repair costs in the event that a severe flood or sustained high flows should occur. Table B-6 summarizes costs and benefits of Plan B. As with Plan A, this plan was analyzed for sensitivity to cropping pattern and yield. However, even with more valuable crops and higher yields none of the six areas would have a B/C ratio above unity., • • Plan B could not be recommended for further study. A detailed analysis is presented in Appendix 10. • • B-15 • No assessment of the economic or environmental attributes has been made by the Kansas City District. Again, reference is made to the HCRS assessment in Appendix 7. • COMBINATION PLANS No assessment has been made at this time on combination plans E, F, and G. Plan E would combine vegetative management with light structural measures. Plan F and plan G would combine the recreation river concept with vegetative management and structural measures. In view of the low benefit/cost ratio demonstrated by plan A, the medium structural plan, it is apparent that plan G would probably not have a benefit-cost ratio above unity. ; Plan G would probably not have a benefit-cost ratio above unity. • Streamflow regulation should also be studied further as a possible option for other plans and as a plan of its own. Studies are presently nearing completion concerning relationships between lake opera- tion and downstream flow conditions at the existing Federal lakes. These studies should lead to some conclusions regarding the potential effects of modification of release schedules. CONCLUSIONS AND RECOMMENDATIONS CONCLUSIONS On the basis of the preliminary assessment which has been completed, no purely structural plans for bank stabilization are economically justified. It is further concluded that there are no environmental benefits to those structural plans which would result in an overall net favorable ratio of benefits to costs. Plans A and B will not be studied further. No conclusions have been reaches for nonstructural or combination plans. RECOMMENDATIONS • With regard to nonstructural plans and combination plans, ongoing studies of plans C, D, E, and F should be continued. Plan G would not be studied further unless plan F is found to be feasible for certain areas. It is anticipated that conclusive results as the merits of these plans will be available in early Fiscal Year 1981. Similarly, studies to better document causes and effects of bank erosion will con- tinue in Fiscal Year 1981.

Existing municipal and industrial water supplies are proving to be inadequate to meet current needs, let alone meeting in- • creased demands of the future; small cities and other water supplying agencies often lack the financial ability to assure themselves of a reliable supply to meet present needs during severe droughts and to provide for future reserves. This description reinforces the need for a study of water supply within an area which may generally be described as northeast Kansas with a portion of southeast and southcen- tral Kansas included. It is the most populous portion of the State. The specific study area is shown on Plate A-1, and the counties included were previously listed on page A-2. This study is a planning effort meant to provide guidance for Federal, State, and local entities which deal with municipal and industrial water supply. The level of planning does not extend to detailed ! engineering studies for any planned improvements. Improvements would be included in a broad range of alternative measures including sources, treatment, distribution, conservation practices, institutional modifications, etc. All possible measures considered shall be discussed. • , That which follows is the first iteration of planning for water supply for the total study area. It be- gins with a description of existing conditions, continues to a discussion of problems and needs, plan formulation with discussion of preliminary plans, assessment and evaluation of those plans, public views stemming from review of this report, and finally the conclusions reached during this first planning iteration. EXISTING CONDITIONS Population. The 1970 population within the 38-county water supply study area was 1,502,719. This population represents 67 percent of the Kansas total, although the study area comprises 31 percent of the State. Table C-1 shows State and study area population data from 1950 to 1970. It is apparent that the majority of the counties experienced declining populations during the 20-year period. - TABLE C-1 , POPULATION, 1950-1970 County 1950 1960 1970 County 1950 1960 1970 Anderson 10,267 9,035 8,501 Linn 10,053 8,274 7,770 Atchison 21,496 20,898 19,165 Marshall 17,926 15,598 13,139 Bourbon 19,153 16,090 15,215 McPherson 23,670 24.285 24.778 Brown 14,651 13,229 11,685 Miami 19,698 19.884 19,254 Clay 11,697 10.675 9,890 Mitchell 10,320 8,866 8,010 Cloud 16,104 14,407 13,466 Nemaha 14,341 12,897 11,825 1 I Dickinson 21,190 21,572 19,993 Osage 12,811 12,886 13,352 Doniphan 10,499 9,574 9,107 Osborne 8,558 7.506 6,416 !

Provisions of the Water Supply Act of 1958 authorize both the Corps of Engineers and the WPRS to provide additional capacity in lakes for municipal and industrial water supply needs. The Soil Conservation Service also has author- ity to include water supply storage in SCS project. Non-Federal interests must agree to pay the costs attributable to the additional storage. Within the study area are 11 of the 24 lakes. They are listed in Table C-3 below along with pertinent data. It should be noted that to date the Kansas Water Resources Board (KWRB) acts as broker for most storage in Federal lakes in Kansas. Entities within the State i make application to the KWRB for water. To date, there exist contracts for 593,200 acre-feet of storage in 5 of the 11 lakes having an estimated firm (2 percent chance) yield of 252.0 million gallons per day. The yields shown in Table C-3 are based on KWRB computations for all lakes except Pomona, for which the yield is based on Corps computations. The SCS has built one structure within the study area which has water supply storage included. This is in extreme southeast Dickinson County near the town of Herington. The structure is on Lyon Creek, has a drainage area of 19.26 square miles, and has 2,144 acre-feet of water supply storage out of a total structure storage of 8,972 acre-feet. • C-3 II II 1 TABLE C-3 DATA ON FEDERAL LAKES . ; • Lake Capacity(Acre-Feet) Water Supply 2% Chance ■ Lake Stream Sediment Conservation Flood Control Total Allocation(AF) Weld(MGD) I Kanopolis Smoky Hill - 61,380" 371,498 432,880 Tuttle Creek Blue 233,000 192,300 1,941,700 2,367,000 Pomona 110-Mile Creek 28,000 70.603 176,773 247,376 1,000 10.2 I Wilson Saline 40,000 248,835 530,710 817,545 Milford Republican 160,000 415,352 757,746 1,173,098 300,000 128.6 Perry Delaware 140,000 243,220 521,880 765,100 150.000 79.5 Melvern Marais des Cygnes 26.000 137.000 200,000 363,000 Clinton Wakarusa 28,500 110,400 258.300 397.200 89,200 18.8 Lovewell White Rock 16,760 24,930 50,460 92,150 . • • Waconda Solomon 60,200 178,900 722,315 963,775 Hillsdale Big Bull Creek 11,000 68,000 81,000 160,000 53,000 14.9 1 Includes allocation for sediment.

It has been estimated that there is 400 to , 500 million acre-feet of water in storage beneath the surface of the State of Kansas, or enough water to cover the entire State to a depth of approximately 10 feet. Perhaps no more than half of this is available I for utilization. Over 65 percent of this water is located in the western third of the State. This.is in con- trast to the surface water supplies which are primarily available in the eastern half of the State. Figure C-3 indicates the areas underlain with groundwater in substantial quantities; the map also indicates the potential yield which may be expected from the groundwater sources. The greatest yields within the study area are found in the alluvial deposits of the Missouri, Kansas, and Republican Rivers where potential yields may exceed 1,000 gallons per minute (g.p.m.) but general- ' ly are in the range of 500-1,000 g.p.m. However, much of the area in the eastern part of the State has 1 little available groundwater, no definable water table, or groundwater which is too highly mineralized ' for domestic use. In summary, the general absence of reliable groundwater sources in the study area , has, in part, discouraged their use for municipal and industrial demands of any significant magnitude within the study area. Water Quality. Water quality can vary greatly, even in proximate areas, depending on such factors as geologic and geographic characteristics and land use. For this reason water quality discussion is i ' separated into five sub-areas which are given in Figure C-4. The areas deviate somewhat from the total study area as previously shown to facilitate discussion. Lake quality is not discussed; however, it can I generally be assumed that impounded waters are suitable for all purposes. Exceptions are noted. • Surface Quality-Area 1-In general, surface waters within the Osage River basin are of good , • ' quality; however, a wide variation in streamflow may produce changes during periods of low flow that C-5 i 1 T 1 AREA'4 j°a"^•• li tioYYrYarr , EA _ 'AREA l !AREA\ 2r man * 1 - •flJtl —'�I•LMl[Y Neoul �-----� .NARY- •1AR T 1 UINR react W11H 4L_Th aAe PISS LN M- raltg1 ii Source: Reference No. 4. FIGURE C-4 • WATER QUALITY DISCUSSION AREAS • Surface Quality—Area 3—Except during high flow periods, the lower reaches of the Solomon and Saline Rivers are highly mineralized, with sodium and chloride concentrations being the principal con- stituents. The Saline picks up most of its mineralization through Russell County. Wilson Lake quality is highly mineralized and is not usable as a potable water source. Smoky Hill River water varies consi- derably in chemical quality throughout its course, and receives a large inflow of chlorides between Salina and Abilene. The surface water quality characteristics of the Saline and Smoky Hill Rivers have been influenced by the operation of the Corps of Engineers lakes. A more detailed discussion of water quality in this area is provided in Section D, Mineral Intrusion. • Groundwater Quality—Area 3—In northern Cloud County, the groundwater from alluvial deposits is high in chlorides. In the Solomon and Saline drainage areas the groundwater supplies are more min- eralized than surface flows; in Mitchell County water is too mineralized for most uses. . • Surface Quality—Area 4— The quality of surface water generally is satisfactory for domestic use, � although quite hard. • Groundwater Quality—Area 4—The water within this area is hard but otherwise of usable quality. ', Groundwater from glacial drift aquifers may be high in iron. • Surface Quality-Area 5—All major tributaries of the lower Arkansas River are high in chlorides and dissolved solids at times of low flows. • Groundwater Quality-Area 5—Much of the groundwater underlying the lower Arkansas Basin is of good quality and totally suitable for municipal and industrial supplies. Institutional Considerations. Water may be supplied on a private, individual basis, or on a collective basis, usually public. There has been and continues to be a trend toward the collective approach where- by a legally instituted entity (public or private) plans and implements a system capable of delivering potable water to customers. Illustration of the importance of these water suppliers is not difficult. • C7 •, it Among Federal agencies, the following five have a role in water supply planning or construction. • Corps of Engineers. This agency may include municipal and industrial water supply storage in dam and lake projects. Of nine Corps lakes existing or under construction in the study area, five have • water supply storage. State or local interest must pay for the cost of the storage, but may do so over a 50-year period. • Water and Power Resources Service (WPRS). This agency, formerly the Bureau of Reclamation, may include municipal and industrial water supply in dam and lake projects constructed principally for irrigation. The WPRS has built two lakes, Waconda and Lovewell, in the study area but neither includes water supply storage. • • Soil Conservation Service(SCS). The SCS may include up to 12,500 acre-feet of water supply stor- age in flood retarding structures under their PL 566 watershed program. Only one existing SCS struc- . ture in the study area has water supply storage. It is on Lyon Creek near Herrington in southeast ' Dickinson County. • Environmental Protection Agency(EPA). This agency is responsible for protecting and enhancing environmental quality and carrying out pollution control functions. It is also charged with administering the Safe Drinking Water Act of 1974, including the establishing of primary drinking water standards. a � 4 v ' �' { a • LAKES ARE POTENTIAL SOURCES FOR WATER SUPPLY • C-9 • • Division of Environment, Department of Health and Environment—Among other duties, this agency has review, permit, and inspection authorities concerning local water supply agencies. It also i'. has the authority to set primary drinking water standards. I' Local water supply authorities are summarized in Table C-7. Among local institutions, the number � • and size of rural water districts have greatly increased over the past 10 to,20 years. Figures C-5 and C-6 illustrate this increase. i, A new local authority for public wholesale water supply districts was created by the State in 1977. These districts can operate on a larger scale than individual agencies in the securing of a source of ■ water. Three such districts have been established. • • TABLE C-7 LOCAL WATER SUPPLY AUTHORITIES .

Both quantity and quality factors will constrain water availability. There are several surface and groundwater supplies with high degrees of reliability, and the State of Kansas has, and is, participating in multipurpose lake development with the it • Federal Government. However, many areas are not located close enough to the reliable supplies to make their use economical on a single agency basis. There are, then, distribution problems which will continue. Water quality needs have been established for several areas, with mineral intrusion being the i� most prominent. Correcting or alleviating the availability needs is expensive and generally beyond of II means those directly impacted. Consequently no significant changes can be projected. 1, The State of Kansas will continue to be a strong force in water resource planning. There is no indi- cation at the present time that the State will become directly involved in the financing or construction of water supply systems. The State government has always been water-conscious since water has been a major factor in the State's economy and quality of life. There is also a realization that the future of Kansas will largely be shaped by the manner in which this resource is conserved and managed. In this respect it is difficult to assume a static condition, but one in which the State may exert increasing influ- ence. The degree to which State involvement is exhibited will have an affect on the accuracy of this , initial forecast. Finally, water supply conservation in residential, commercial, and industrial usage must be consid- ered a factor in development of the "without condition," even though its impact cannot yet be defined. ' � Supplying agencies which face an expensive capital improvements program may elect to pursue conser- vation techniques which permit a delay in construction. Conservation will also increase as a response to the increasing awareness that water is too valuable a resource to waste. As the study progresses, steps will be taken to determine the future role of conservation within the study area to the end of producing of more accurate picture of actions that will be taken to satisfy future needs. PROBLEMS AND NEEDS Problems and needs may be associated with the source of supply, which may be a flowing water- course, groundwater, or an impoundment of some type; the treatment of the supply to potable stand- ards; or the distribution of the potable supply to customers or to an area of demand. They may also be associated with the institutional aspects of supplying water. Financing is an institutional consideration a of great importance. It is the purpose of this subsection to describe those defined problems and needs II of the study area toward which this study should be directed. Long Term Water Requirements. Projected water supply needs have been compiled by the Kansas Water Resources Board. Survey data on urban and rural domestic demands were used to estimate public water supply demand for future years. Urban domestic, rural domestic, and industrial water uses from public water systems in 1975 are shown in Figure C-7. Within the study area urban domestic usage was estimated to be 53.2 billion gal- Ions per year, or 146 million gallons per day; people living in rural areas used about 7.1 billion gallons per year, or 19 million gallons per day; and, industries obtaining their water from public systems ac- counted for an additional 103 billion gallons per year, or 29 million gallons per day. Figure C-8 shows anticipated demands for 1985 and 2000 for the study area. Total water usage is forecast to increase from 70.7 billion gallons annually in 1975 to 82.6 billion gallons in 1985 and to 98.0 billion gallons by the turn of the century. Converted to a million gallons per day unit, the increases are from 191.4 in 1975 to 223.8 in 1985 and 266.1 in the year 2000. ' , Figure C-9 provides data concerning public water supply needs above 1975 usage for 1985 and 2000 and is developed from the previous two figures. Needs were identified by making the assumption that ' present supplies would meet 1975 needs but additional demands for 1985 and 2000 would represent an unfulfilled need. The 1975 water use for the study area was estimated at 194 million gallons per day. Based upon the assumptions made in the analysis, water demands are expected to increase by 32 million gallons per day by 1985 and 76 million gallons per day by 2000. There is a great disparity in future needs on a county by county basis. The heavy water supply demand areas of Sedgwick County and the counties along the Kansas River corridor with population centers at Salina, Junction City, Topeka, Lawrence, and in Johnson and Wyandotte Counties, all show • high values for future needs. This indicates at least the expansion of treatment and distribution sys- C-13 • • short-term water supply situation in Kansas. Figure C-10 displays the problems of shortage and quality while also showing the location of the need. In many cases the quantity and quality problems are clustered together. Such clustering indicates locations where needs are greatest and alternative solutions involving several public supplies might be possible.

Some public water supply problems are caused by •I inadequate treatment and distribution facilities rather than by inadequate sources. A treatment plant ,' must not only produce potable water capable of meeting Federal and State quality standards, but also have sufficient capacity to keep up with peak demands which usually occur during the summer with such activities as lawn watering or car washing.When an increase in required capacity is required for a future year, planning and construction lead time should be enough to insure completion by the time the need materializes. Although no data was gathered on the condition and capacity of each treatment faci- lity within the study area, it is usually the case that smaller public supplies in rural areas have the greatest difficulty in monitoring capacity needs and then increasing capacity by the critical time. This • stems from a lack of planning expertise and funds to make the improvement. C-17 . Table C-8 presents a summary by county of the relative susceptibility to drought by public supplies. I� . Only 14 high susceptibilities were noted. Considering that several components of the supply mechanism were considered in assessment, and with the knowledge of the many problems which surfaced during ii the moderate drought of 1976-1977, this number may be rather low. Referring to Figure C-10, which . ' • located the quantity and quality problems resulting from a 1977 questionnaire, the differences are more apparent.

It is important that all be listed as background information to the plan formulation process. The following types of alter- natives were examined: • Managing water demand through residential water saving practices; ,. • • recycling filter washwater and coagulation—sedimentation wastewater; • reducing distribution system losses; • reuse by industry; • recycling wastewater; • dual water systems; • pricing and/or metering; • short-term mandatory use restrictions; • groundwater sources; • • flowing streams and diversions; • • lakes, impoundments and diversions; • distribution systems&transmission mains; • water treatment plant additions or expansions. The following discussion considers each of these measures in turn. Generally, a combination of the measures will provide the best solution for a specific situation. Likewise a combination would usually be most appropriate for inclusion in a plan which must address a number of needs. Managing Water Demand Through Residential Water Saving Practices. There are many ways in which residential water users may reduce use. Table C-10 lists the five basic categories of residential use and the nation-wide averages for relative percentage of domestic, or in-house, use and total resi- dential use. TABLE C-10 . RESIDENTIAL WATER USE BY CATEGORY Average Water Use Category Domestic Total Residential • • Drinking and Cooking 5% 4% Laundry and Dishes 20% 17% Bathing and Personal 35% 30% Toilets 40% 34% Lawn Sprinkling, other outside uses — 15% Total 100% 100% Water saving fixtures and appliances are now sold which are capable of reducing water use while performing as well as their water-wasting counterparts. Shower, lavatory, and sink fittings with built-in flow regulators and valves have the widest application. Flow regulating shower heads could reduce the amount used for bathing by as much as 50 percent. There are also waterless toilets. Since it is esti- mated that toilet flushing accounts for 40% of in-home water use, elimination of this quantity of water would result in dramatic water savings. Most waterless toilets use chemical additives for decomposi- tion; however, there is now a model on the market which employs the biological process. Local ordi- nances would have to be reviewed prior to implementation of such a water-saving technique. Dish- washers and clothes washers have now been modified to reduce the rinse waters required. Recent studies have shown that complete use of water-saving fixtures and appliances could reduce total water use in the average household by as much as 35 percent and savings for commercial and business estab- lishments could be as high as 50 percent. There are several legal actions which may have some applicability in a program of conservation. The legal action would be in the form of various types of legislation which can be placed in the following three categories: permissive, restrictive, and tax incentives/disincentives. Permissive legislation could involve: • modification of building codes and state health and water quality laws to allow the use of recycled • water for domestic or other needs; • allowing the construction of dual water supply systems; • • allowing the use of new technological advances such as waterless toilets. C-23 • '1 adequate mixing and reduction of any contaminants by dilution to levels that permit attainment of standards after treatment in a water treatment plant. Such treatment must be technically and economically feasible. Dual Water Systems. It is estimated that as little as 10 percent of the water used in a water supply • system actually needs to be treated to potable standards of quality. Uses such as lawnwatering and • firefighting would not require potable water. A dual system, then, would separate supplies into potable and non-potable categories. Parallel mains would need to be constructed and this would be a complicated procedure requiring • extensive disruption in developed areas. Many political, technical, and financial problems would be associated with the implementation of such systems. Pricing and/or Metering. Modifications in pricing policies become possible when there is universal metering. Most water supply agencies still assess progressively lower charges per unit as more water is . consumed. This is termed "declining block" water pricing. Therefore, there is little incentive to reduce use because the average unit price of supply becomes cheaper as more water is used. Many believe that this policy should be reversed, so that higher charges per unit would be assessed as more units were consumed. This would amount to a financial penalty for excessive consumption and be an incen- tive for individual conservation. Efficiency would also be improved by pricing policies which charged more at time of peak demand and less at slack demand. The peak demands observed during hot, dry periods cause water supply agencies to develop system capabilities far in excess of what would be developed for average use periods. Modifications to pricing policies could help to insure that those customers with the greatest demand would be those paying the incremental costs of the development • of oversized systems. Such policies would be especially beneficial in reducing sprinkling demands in an area such as northeastern Johnson County where a high percentage of use is residential. Some cities do not meter water use by individual consumers and accordingly have no way of meas- uring water use and charging for the amount used. Instead when no meters are used it is common practice to charge a flat rate for water service, e.g. the same charge regardless of the amount of water used. Without the ability to charge for the amount used, which the installation of meters offers, there is no financial incentive for customers to conserve. Just the physical presence of a meter encourages the user to be more aware of the amount of water being used and wasted. A decrease in usage results and there is some evidence that the decrease will remain fairly constant over time. Several studies have been completed which have attempted to evaluate metered versus non-metered, flat rate usage. In parts of Washington, D.C., when meters were introduced, there was a decrease in usage of about 36 percent. Another study of 35 cities, some of which were predominantly metered and some not, showed the metered cities' per capita use was less than half that of the unmetered cities. Short-term Mandatory Use Restrictions. During times of crisis, cities often resort to mandatory use restrictions. These restrictions may be bans on certain outside uses, for example lawn sprinkling or car washing. In times of severe or more prolonged shortage, restrictions may be applied to total residential . use. There is usually strong public acceptance for such measures where restrictions are reasonable and equitable, and where a demonstrable crisis exists. Groundwater Sources (Well Field Expansions). Groundwater is used extensively in the study area. Figure C-3 on page C-6 may be referred to for location and estimated yields. The Missouri River alluvium is the most reliable groundwater source of the study area. Spacing of wells would be important in maximizing the yield. The quality is consistent and is generally not influ- enced by surface water quality. The development potential of this source is great. The Kansas and Republican River alluvium yields are small in comparison to that of the Missouri River alluvium. Also, both the quantity and quality of the water are influenced by surface flows. How- ever, they should still be considered as two of the more reliable sources of the study area. Again, well spacing would be important in maximizing yields. There are other groundwater sources used by the smaller water supply agencies and they may be categorized as tributary alluvia, glacial drift, and sand- stone and consolidated rock aquifers. None of these sources have the potential of providing a safe yield of much more than one mgd and most provide much less. Even though the development potential of these sources is not great, some are adequate for small agencies that are not expecting rapid and • sustained growth. Specific yield data on these sources are limited.

FIGURE C-11 POTENTIAL SMALL LAKE SITES • • • Water Treatment Plant Additions or Expansions. This is an obvious addition to the list of alterna- tive solutions. The manner in which the capacity increase is made makes this an important alternative, and several arrangements are possible. The large number of agencies currently operating plants may continue operation; some agencies may choose to discontinue operation in favor of purchasing treated • water; agencies may modify their treatment processes (but Safe Drinking Water Act standards must be met); and agencies can anticipate capacity increases, or delay and face operational problems. This is an alternative that is included in most plans since the action is unavoidable. Screening. Based on the preceeding initial assessment of possible measures, Table C-12 was pre- pared to display the relative poential of the measures in solving municipal and industrial water supply needs. • • C-29 completed at some time. No attempt will be made to cover this myriad of documents, although through- out the course of the study many will be examined and incorporated where appropriate. The following paragraphs identify regional studies and reports concerning water supply. Kansas State.Water Plan. By executive and legislative directives, the Kansas Water Resources • Board has been charged with the responsibility of the overall coordination of the State's interest in the development of the water and related land resources. As a result of these directives, the KWRB initiated studies on a water resources policy and program for the State which includes financial partici- pation and assistance. This action culminated in the enactment of the State Water Plan in 1965 by the Kansas Legislature. The State Water Plan is meant to provide a broad policy for the development of a well-balanced, coordinated, and comprehensive water program. Of particular interest to this report is the purchase of storage in Federal lakes by the State for the purpose of water supply. Southeast Kansas Water Supply Study. The Kansas Water Resources Board has been conducting a cooperative study with the Soil Conservation Service to investigate water supply problems and solu- tions in the Verdigris, Neosho, and Marais des Cygnes (Osage River as called in this study) basins in southeast Kansas. The study purpose is to investigate and compare costs for providing water supply to cities, rural water districts, and rural communities with known supply needs. A broad range of alterna- tives is being developed to provide a number of choices. This study is similar in scope for southeast Kansas to the study of northeast Kansas which this Reconnaissance Report documents. Kansas "208" Water Quality Management Plan. The U. S. Congress, in passage of Public Law 92-500, the Federal Water Pollution Control Act, directed the preparation of detailed water quality man- agement plans which would consider all significant pollution sources including municipal, industrial, •urban stormwater, agricultural, silviculture!, salt water intrusion, construction, residual pollutants and the ultimate disposal of wastes such that ground and surface water would be protected. The Congress further stipulated that States and designated regional areas would utilize these plans in managing pro- grams for control of discharges from municipal, industrial and feedlot sources. The State of Kansas has completed an approved Water Quality Management Plan, with recommendations for managing the various types of pollution into State waters. Planning conducted as a part of this water supply study must be coordinated with these recommendations. Four Rivers Resource Conservation and Development Plan. This plan was developed through assistance of the Soil Conservation Service. The plan includes the counties of Cloud, Ellsworth, Jewell, Lincoln, Mitchell, Ottawa, Republic, and Saline. The purpose of the planning effort was to evaluate present resources, their use and availability, and to develop a framework plan of actions to improve resource use in the future. The plan, completed in 1975, concluded that there was a need to further, develop water supplies and effectively utilize and distribute existing sources. • Lake Region Resource Conservation and Development Plan. This plan was developed through assistance of the Soil Conservation Service. The plan includes the counties of Anderson, Coffey, Frank- lin, Linn, Miami, and Osage. Coffey County is not included in the study area of this Reconnaissance Report. The plan was to result in actions, policies, and decisions necessary to provide a productive and sustained resource base for the participating counties. The plan, completed in 1976, recognized the water supply needs of the area and recommended a detailed study of existing supplies and future water needs. DESCRIPTION OF PRELIMINARY PLANS The study area is large with over 4®water suppliers and rural communities which planning must consider. At this stage in the study no attempt is made to develop plans for each portion of the area, in advance of needed data collection that will support formulation. However, based on examination of the screening of measures and plans of others, it is possible to establish a range of broad conceptual plans. The plans can be prepared without necessarily pertaining to a specific area, but haveigenerally applica- tion throughout the study area if the needs situation warrants. The generalized concepts will be used as a pattern when detailed plan formulation begins. • C-31 • • WATER SAVING DEVICES METERING HOOK-UP FEES .c ._ ( PRICING REDUCING DISTRIBUTION SYSTEM BUILDING LOSSES ORDINANCES USAGE RESTRICTIONS e PUBLIC EDUCATION FIGURE C-12 MEASURES CONSIDERED FOR CONSERVATION PLAN Conceptual Plan 3 is the Use of Large Lakes. The thrust of this plan would be maximum utilization of those lakes which are located within or near the study area. These lakes were previously shown on Plate A-1. Transmission is an essential part of this plan and treatment would be included as necessary. The lakes, of course, were authorized by Congress for specific purposes with specific volumes allocated to those purposes. The data was previously given in Table C-3 on page C-5. Water supply is not present- . ly an authorized purpose in all of the lakes. However, no constraints were placed on planning at this time because of the set allocation for water supply, thus providing flexibility in preparation of plans by being able to consider a broad range of required water supply storage volumes. Figures C-14 through C-17 illustrate possible utilizations for the large lakes, each of which may loosely be described as a plan. • Figure C-14 shows that demand may be concentrated in close proximity to a large lake. There are two options available when the distribution and treatment functions are,added. First a number of indi- vidual suppliers may choose to utilize the lake. The second case involves cooperation among all entities of the area of demand. All would share in the implementation of treatment and distribution. Figure C-15 shows what may be the most common plan. Lake location and demand location, which cannot be planned to correspond, present a situation where pumping of water must occur for some distance. One lake may be used to supply several areas of demand. Figure C46 demonstrates the interconnection of large lakes. Where there is an inordinately large demand in close proximity to a lake which has a limited capacity for water supply, it may be possible to • link this lake with another having excess capacity. A raw water transmission main is required. It is pos- • sible, as shown, to make more than a single connection. • C-33 - k • • AREA OF DEMAND FIGURE C-15 UTILIZATION OF FEDERAL LAKES - CASE 2 AREA OF DEMAND REMOVED FROM LAKE 3 LL_,SL�n LARGE DEMAND DEM AREA /1' ( INADEQUATE E f CAPACITY • FIGURE C-16 UTILIZATION OF FEDERAL LAKES - CASE 3 INTERCONNECTION OF LARGE LAKES • • C-35 9 WELL FIELD tr-�'i1' '1T • • n i �f q TREATMENT _ AREA OF � `_ _ DEMAND FIGURE C-18 UTILIZATION OF GROUNDWATER A TYPICAL APPROACH Conceptual Plan 5 is Treatment and Distribution. Both measure have been discussed to a limited degree in the previous conceptual plans; however, an expanded discussion is required to provide necessary detail and to illustrate that these two components may be considered as plans either jointly or separately. Treatment is usually required to make raw water potable and to be in conformance with potable standards established by the State of Kansas and the Environmental Protection Agency. Table C-13 presents the current Primary and Secondary standards. Treatment can most typically be classified in three categories. They are: (1)conventional; (2) conventional plus softening; and (3) disinfection only. Only with the utilization of a high quality groundwater should disinfection only be considered. Treatment usually consists of the processes of pre-sedimentation, coagulation-sedimentation, filtra- tion, and disinfection. Softening is added if water is considered objectionably hard. In the case of the study area, several additional processes might be considered as a part of a treatment plan. Mineral intrusion is a defined problem for certain areas within the larger study area and it is possible that treat- ment for reduction of sodium and chloride concentrations in a given source may be an alternative to ' development of a new source. In that case ion exchange, distilation, reverse osmosis, or electrodialysis . may be considered as an additional process. Split treatment may also be considered in which case one of the four processes listed above would be used for a portion of the water treated while the remainder would receive normal treatment. The resultant quantities could be mixed to provide a product within the limits of acceptability. Treatment, as an integral part of a treatment and distribution scheme, would be on a larger scale than for a single public supply. A cooperative effort with several suppliers would be likely. This would occur because of the economies of scale possible with construction of a larger plant, i.e., the cost per unit of treatment plant capacity would be less. Conceptual Plan 6 is Diversion to Sedgwick County. This is the most specific of the plans listed as it is site specific. The area of demand has been identified and the potential sources and means of delivery determined. The diversion amount could be as high as 50,000 acre-feet per year, which is about 45 million gallons per day. The size of the transmission main would probably be in the 48 to 72 inch diameter range. The two possible sources are Kanopolis and Milford Lakes. Figure C-19 shows show some of the routes by which this alternative can be accomplished. As can be seen, variations include several of the previous types of plans including use of Federal lakes, trans- mission, interconnection of lakes, and instream release. Conceptual Plans 7(and up) Involve Useage of Combinations of Other Plans. After a more detailed evaluation of Conceptual Plans 1 through 6 is complete, it will be possible to combine elements of the plans in various ways. In all likelihood a combination of conservation measures and structural sources, along with treatment and distribution, will be the best approach in some parts of the study area. SUMMARY Seven different conceptual plans have been presented. With almost every plan the basic tenent is • to provide sufficient source capacity and this is done in a variety of ways. In some cases sources are C-37 . _ CLOUD _ - .MI T GHELL cl'A O ____1 $ I r; CLAY (+114.1 , C _ RILEY • •' Saline AVrw OTTAWA LINCOLN _ I Man RI I C• GEAR?_� I Wi �• ioo 7y 4 to L I COUMC/L N.

It is possible • to do this because of knowledge of the nature of the measures under consideration. No attempt will be made to identify specific impacts of the seven plans or their components; instead, general impacts are summarized below in Table C-15. • Evaluation usually involves subjectively comparing the beneficial and adverse contributions of each . alternative plan. Plan impacts, when clearly defined, are analyzed to determine the beneficial or ad- verse value of the contribution each plan would make when compared with what would happen in the absence of carrying out any of the plans. Then the relative contributions of the alternative plans are ranked and traded-off based on professional analysis and the perceptions of the public. At the conclu- sion of the planning process the results of evaluation provide the bases for selecting the most desirable . plan. • At this planning stage, however, evaluation must be less detailed and concentrated on analyses which determine whether a continuation of the study is warranted. There is also no need to evaluate each plan individually; rather, they would be examined as a whole. Following is a series of questions, . • the answers to which will form the basis of determining the future course of the study. • C-41 • QUESTION 5 - Do the plans individually or as a group have the potential to satisfy the stated plan- ning objectives (See page C-24 for planning objectives). ANSWER 5 -Yes. • QUESTION 6 - Is there public support for this type of planning effort? ANSWER 6 - Yes. There appears to be a broad recognition that planning is required. Various state agencies, which are representatives of the "public" are supportive of the planning and are actively cooperating and participating in the study. QUESTION 7 -Are there other supporting reasons, at this time, to pursue a study of this nature? • ANSWER 7 - Yes. Perhaps one of the most cogent reasons is the opportunity presented to reanalyze the current storage allocations of the Federal lakes within the study area. There are now several requests for storage in lakes for municipal and industrial supply where a specific water supply alloca- tion.does not now exist. There is also a need to examine the total needs of the study area and attempt to correlate those needs with available supply. These large lakes are the most reliable sources within the study area. Their utilization by means of a distribution system or transmission main provides an important problem solving approach. Only through examination of the study can all the opportunities for utilization be discovered and compared with other means. An additional reason concerns the mineral intrusion aspect of the study. Mineral intrusion has been defined as a substantial problem, with an adverse impact to water supply. These two study purposes should be meshed in order to fully explore their cross impacts. CONCLUSIONS AND RECOMMENDATIONS Based upon the previous documentation of the first iteration of the planning process for water supply in northeast Kansas a number of conclusions can be reached. They are as follow: CONCLUSIONS • There are a significant number of unmet water supply needs within the study area. • A broad range of management measures is available which have some potential for needs fulfillment. • Plans can be developed which can significantly contribute to planning objective fulfillment. • There are no factors technical or institutional, that would preclude implementation of the types of plans presented. • There is substantial support within the State of Kansas for this study to continue. • There is a valuable side-benefit of lake reallocation studies which can be accomplished simultane- ously with the overall study effort. • Water supply should be studied simultaneously with mineral intrusion. Based on the above conclusions, it is recommended that RECOMMENDATION The water supply study should be continued into Stage 2 planning with alternative structural and nonstructural plans formulated, assessed, and evaluated in accordance with Water Resource Council Principles, Standards and Procedures. • • C-43 SECTION D MINERAL INTRUSION 1 MINERAL INTRUSION TABLE OF CONTENTS • Page PROBLEM IDENTIFICATION D-1 Existing Conditions D-1 Area 1 D-2 Area 2 D-3 Conditions if No Federal Action is Taken D-13 Problems, Needs, and Opportunities D-13 Problems D-13 Needs and Opportunities D-13 Planning Objectives D-14 FORMULATION OF PRELIMINARY PLANS D-15 Management Measures D-15 Interception D-15 .

Total dissolved solids (TDS) represent all the mineral constituents in water, and provide one indicator of possible problems in water use. In the study area, mineral intrusion is found , primarily in the form of chloride, sulfate, and hardness. The term hardness refers to soap-consuming minerals in water such as calcium and magnesium. The suitability of water for drinking or for industrial or irrigation use is dependent on the extent of mineralization, as well as other parameters. For municipal and industrial purposes, The Environmental Protection Agency (EPA) has established "secondary maximum contaminant levels" for minerals as follows: TDS 500 mg/I (milligrams per liter) Chlorides 250 mg/I Sulfates 250 mg/I Hardness 500 mg/I Secondary levels are guidelines which represent reasonable goals for drinking water quality. They are not federally enforceable. Secondary levels should not be confused with primary maximum levels for contaminants which may adversely affect the health of persons. There are not primary levels on the mineral parameters listed above. A further descriptive classification of water into several categories according to the degree of dis- solved solids is desirable. For the purpose of this report, the following categories are applied: Total Dissolved Solids Classification Concentration, mg/I Fresh water Less than 1,000 Excellent Less than 250 Good 250 to 500 Fair 500 to 1,000 Saline water More than 1,000 Slightly saline 1,000 to 3,000 Moderately saline 3,000 to 10,000 Very saline 10,000 to 35,000 Brine More than 35,000 This classification is based on the effects of minerals in the water. At chloride concentrations over 250 mg/I, water begins to taste salty and corrosion of steel and aluminum begins to increase. Sulfates may cause problems for some industrial uses when over 100 mg/I, and when concentrations exceed 250 mg/I water begins to taste bitter. Hardness of over 500 mg/I can cause residential and industrial problems by forming scales in boilers, hot-water heaters, water pipes, and water-using appliances. However, unlike chlorides and sulfates, hardness can be reduced to about 100 mg/I by common water treatment softening methods. There is no inexpensive method for desalinization, or reduction of chlo- rides and sulfates in water. Desalinization processes are being used only in locations where there is not an adequate fresh water source. EXISTING CONDITIONS The intrusion of minerals into surface waters of the Kansas River and several major tributaries is a long-known condition which has been studied and reported in a number of earlier documents. A recent report which presents a good overview of the condition is Mineral Intrusion in Kansas Surface Waters—a Technical Report, 1978, prepared by the Kansas Water Resources Board. Excerpts from that • report are drawn on in the following discussion. D-1 Wilson Lake on the Saline River in eastern Russell County receives much of the salt intrusion from Area 1. The lake stabilizes salt concentrations downstream, but lake water has an average chloride content of about 800 to 900 mg/I. Area 2. This area is in eastern Saline and western Dickinson Counties. Most of the intrusion comes from the Wellington geologic formation, moving up through the alluvial aquifer and into the Smoky Hill River along a reach from the mouth of the Saline River downstream about 25 miles. The effect on average chloride content in the Smoky Hill River is shown in Figure D-3. Figures D-4 through D-11 provide a schematic view of various water quantity and quality parame- ters in the study area. The figures indicate the percentage contribution of the major tributaries for each parameter displayed. For example, Figure D-4 shows that the Smoky Hill River at Enterprise drains 32 percent of the total drainage area of the Kansas River basin at DeSoto (59,756 square miles). Similarly, Figure D-5 shows that the Blue River at Manhattan provides 28 percent of the mean discharge at De- Soto (6,900 cfs). Figures D-6 and D-7 display low flow contributions, with Figure D-6 representing the more severe low flow condition. Figure D-8 shows values for chloride contributions by weight based on the product of mean flow times chloride concentrations which occur at mean flow. Figure D-9 is a simi- lar display of the 90% exceeded low flow times chloride concentrations at that flow rate. Figures D-10 and D-11 display sulfate contributions for mean flow and low flow conditions. The percentages shown in these figures are not intended to be directly additive or cumulative. . Each station was computed individually based on historic data for that station. Differences in perdiod of record and omission of smaller tributaries account for apparent discrepancies. iOTT _ — - _ j LINCOLN So/me - Mbi/ Lincoln •f Bhl '4w� 720 c1 .I River Tescott 239504 FairpOft Wi/sal) 30090 75041 A (I c1 . oke 400904 • E L L I S 188304 I t 1530c1 70 Hays 70030 — — — — — Russell ❑ h— lei.

The mineral intrusion has been occurring naturally over a long period of time, and would be expected to continue. The only govern- mental action presently being taken is limited to one aspect of the problem which is the occasional high • chlorides (over 250 mg/I) in the Kansas River at Topeka. If requested by the Kansas Water Resources Board, outflows from the Corps' Tuttle Creek Lake are sometimes increased up to the amount of inflow during those periods to dilute the chloride concentration of Kansas River water. There is, however, no authorized storage in Tuttle Creek Lake or other lakes for the purpose of dilution. It is expected that those reaches of the Saline and Smoky Hill Rivers which have not been usable for irrigation or municipal and industrial water supply would remain unusable in the future. There are no known Federal, State, or local plans to alter that condition. PROBLEMS, NEEDS, AND OPPORTUNITIES Problems. There are three principal economic problems associated with mineral intrusion. These problems concern the use of water for (1) irrigation, (2) industrial cooling and processing, and (3) do- • mestic needs and livestock watering. It is not possible to apply precise water quality requirements for each of these uses, but some guidelines apply. For irrigation use, slightly saline water (1,000 to 3,000 mg/I) may cause such problems as reduction in crop yields, reliance on salt-tolerant crops, and cumulative build-up of surface soil layer salts eventu- ally leading to soil sterility. Leaching, the occasional flushing of salts out of surface soils may be neces- sary. Salt-tolerant crops include barley, cotton, and sugar beets, none of which is a major crop in the study area. As an example of the potential adverse effect of irrigation with saline water, it is reported that in southern Iraq 20 to 30 percent of the cultivated land has been abandoned in recent years due to salt built-up, and crop yields on other land have decreased by up to 50 percent. In the study area, the Saline River is generally not usable for irrigation from western Russell County downstream to its juncture with the Smoky Hill River. Wilson Lake is also not usable for irriga- . tion. The Smoky Hill River is occasionally too saline for irrigation use from the Saline River downstream to Abilene. Much of the Smoky Hill valley alluvial aquifer between Saline and Abilene is also not usable for irrigation. ' Many industrial processes are precluded by high chloride or sulfate water supplies. It is not possi- ble to define a practical limit on salinity for cooling purposes, but moderately saline water would very probably cause an unacceptable amount of corrosion and slightly saline water may also be unacceptable for continuous use over a long period of time. • Saline water should not normally be used by municipalities. In order to avoid using saline water, • some communities in the study area have developed more costly sources of supply. Outside the study area, the city of Wichita must blend two sources, one saline and the other fresh, to obtain a sufficient quantity of acceptable water for present demands. In Russell County, the cities of Hays and Russell have had water supply quantity problems, but are unable to use the Saline River because of its salinity. The city of Saline occasionally must discontinue the use of a well for a period of time when salinity levels are too high. Topeka, Lawrence, and Johnson County Water District No. 1 all use the Kansas River as a water supply source. Topeka has recorded a number of occasions when chloride levels have equaled or exceeded 250 mg/I as shown in Table D-1 Needs and Opportunities. Based on the problems related to mineral intrusion as presented in the preceeding section, a number of needs and opportunities are evident. Reduction in mineral intrusion could aid or accomplish the following: • Increased irrigation use of the Saline and/or Smoky Hill Rivers. • Increased irrigation use of the alluvial aquifers of the Saline and/or Smoky Hill River valleys. • • Industrial use of Wilson Lake, especially for cooling water. • Use of the Saline and/or Smoky Hill Rivers for municipal water supply by several cities, towns, and water districts. • Continuation of use of the Kansas River for municipal water supply by Topeka, Lawrence, and Johnson County Water District No. 1 during low-flow periods. • • D-13 (4) occurrences of chloride levels exceeding 250 mg/I in the Kansas River will be reduced or elimi- nated, thus providing improved dependability of the river for domestic use, and (5) environmental attributes of the Saline and Smoky.Hill Rivers and Wilson Lake will be enhanced, maintained, or preserved. � • It should be recognized that any or all of the above objectives may be impractical to achieve, either from an economic standpoint or for other reasons. Nevertheless, a number of possible measures are available for consideration which could reduce the mineral intrusion and thereby serve one or more of the above objectives. These measures are discussed under Formulation of Preliminary Plans. FORMULATION OF PRELIMINARY PLANS • MANAGEMENT MEASURES The first step in the formulation of plans is to identify specific measures to reduce mineral intru- sion. These are not plans, but elements from which plans can be formulated. Some of the measures • relate primarily to collection of saline water and other measures related to disposal. The following measures have been identified in prior reports as possible mineral intrusion control measures. Interception. This measure would involve drilling a series of wells to intercept saline groundwater. The water would be pumped to the surface and collected for disposal. In-channel Storage. This measure would involve retention and storage of mineralized surface water in the river channel. Fresh water flows would be diverted around the stored saline water via a canal or new channel. Reduction of Recharge. It may be possible to reduce mineral intrusion by reducing high flows and flooding over the alluvial recharge area to the subsurface mineral deposits. To a degree, existing Federal lakes may have accomplished this. A.plan of this type does not appear to be feasible for the study areas. Hydrostatic Pressure. Construction of low-head dams or levees over the saline springs and seeps where salty groundwater is emitted into the stream system may produce enough hydrostatic pressure • to reduce salt inflow. • Transport. A measure which would probably be necessary to some extent for all plans is the trans- port of saline water from collection point to disposal location. Transport could be accomplished by canal or pipeline. Evaporation. Evaporation ponds or basins could be used to reduce the volume of collected saline water. Accumulated waste salts from an evaporation process would have to be disposed of periodically. Use of salts for commercial purposes is a possibility, depending on the chemical make-up of the salts. Subsurface Disposal. This disposal measure would involve the injection of collected saline water into deep formations. For many years, brines brought to the surface during oil and gas production have been disposed of in this manner. Presently most disposal is made in geologic formations at depths of 3,000 to 3,200 feet in the Salina area. Release During High Flows. A possible disposal measure would be the release of stored•saline water to the river during high flows. Releases would be made when river water is low in minerals and would not be adversely affected by the additional salt load. Desalinization. There are several processes by which salts can be removed from water. In other areas these processes have been found to be uneconomical unless fresh water is otherwise virtually unattainable for municipal use. Desalinization will not be considered as an alternative in this mineral intrusion study. It may be considered in the water supply study where a critical municipal water supply situation exists. Dilution. Dilution of saline surface water or fresh water which exceeds 250 mg/I of chlorides may be accomplished by mixing with higher quality fresh water. This could be accomplished by making releases from one of the existing Corps lakes. This measure would require the allocation of storage in the lake for the purpose of dilution. No Action. This measure would result in a continuation of mineral intrusion as described in a previous section, Conditions if No Federal Action is Taken. • 4 • D-15 • • • the potential benefit in converting storage to mineral intrusion reduction would be more than offset by • the loss in irrigation benefits. Wilson Lake has chloride levels exceeding 500 mg/I and is not itself usable • for irrigation. The no action alternative would, of course, not reduce intrusion but it may be the only practical alternative at this time. Table D-2 summarizes some of the potential effects of the alternative • plans for this area. As previously stated, the effects are based on very limited data. • • TABLE D-2 .

Mineral intrusion is more confined in this area than in Area 1. Available data indicates that a line of relief wells across the Smoky Hill-Saline valley just east of Salina may be highly effective in intercepting saline flow and reducing intrusion. Disposal, either by subsurface injection or evaporation, would be much less costly for this area than for Area 1. In-channel storage would also appear more economical and more effective for Area'2 than Area 1 because a shorter diversion canal would be required. Hydrostatic pressure would not be as effective as other plans because only a portion of the seeps and springs occur in locations where a low dam or levee could be built. At those locations where seepage is directly into the river, this measure could not be used. Dilution could be highly effective in reducing occasional high salinity of the Kansas River, provided that one or more monitoring stations would be established upstream near controlling lakes to forecast the need for diluting flows. The no action alternative would simply allow the existing mineral intrusion problems to continue. Table D-3 presents a preliminary effect assessment summary for Area 2. • • • • .

The purpose of the three-stage process is defined in a Corps of Engineers Regulation (ER 1105-2-210) from which the following excerpts are taken. STAGE 1—RECONNAISSANCE The purpose of the first stage of the planning process is to conduct reconnaissance level investi- gations to determine whether a survey scope feasibility study is warranted and, if warranted, to devel- op a detailed scheme for stage 2 planning. Emphasis should be on problem identification. Plan formula- tion and evaluation is concentrated on identification of possible management measures and potentially significant impacts. STAGE 2—DEVELOPMENT OF INTERMEDIATE PLANS In this stage, a broad range of alternative plans and management measures are explored. Stage 2 studies result in a screening of alternatives by carrying out sufficient iterations of the four planning tasks(problem identification, formulation, impact assessment, evaluation)to decide which plans, if any, - warrant more detailed study in stage 3. The stage 2 screening will reduce the number of alternatives to those which are most feasible. STAGE 3—DEVELOPMENT OF DETAILED PLANS Stage 3 emphasizes the detailed assessment and evaluation of a small number of alternatives. It involves carrying out the four planning tasks to a level of refinement which assures that each of the . plans considered in stage 3 is formulated in the best possible way to achieve the desired planning objectives. Studies should assure that each of the plans is implementable and should support selection • of the best plan. Stage 3 should also include further development of the selected plan to support a recommendation for Congressional authorization for Corps of Engineers implementation, if necessary criteria are met. The primary documentation in stage 3 will be the draft and final study report. An Environmental Impact Statement should be prepared if federal implementation action will be proposed. MILESTONES Eleven significant events are designated as indicators of physical progress. Those events are scheduled for accomplishment as follows: Milestone Description Date 1 Study Initiation 7-76,1-79 2 Approved Reconnaissance Report 10-80 3 Submit Stage 2 Report . 5-81 4 Stage 2 Checkpoint Conference 7-81 5 Complete action on Conference Memo 8-81 6 Submit Draft Report and DEIS 6-82 7 Stage 3 Checkpoint Conference 8-82 8 Complete Action on Conference Memo 10-82 9 Coordinate Draft Report and DEIS 2-83 10 Submit Final Report and RDEIS 2-83 11 Division Engineer's Public Notice 9-83 E-1 SUBACCOUNT 08, SURVEYING AND MAPPING Bank stabilization work in this subaccount is nearly complete. Mapping will be limited to the severe erosion areas on the Kansas and Smoky Hill Rivers. Surveying for water supply and salt intrusion studies will cover possible structure locations (water supply lake sites, evaporation pond sites, pipe- lines). Mapping will concentrate on display of intermediate plans and impacts related to those plans. SUBACCOUNT 09, HYDROLOGY AND HYDRAULIC INVESTIGATIONS • We will analyze bed and bank sample data and results of channel migration studies to refine alter- native plans at severe erosion sites and to predict the effectiveness of plans. Regarding water supply, hydrologic analyses of potential lake sites to determine yields will be performed, as will hydrologic real- location studies of Melvern, Pomona, Tuttle Creek, and Wilson Lakes. SUBACCOUNT 10, FOUNDATIONS AND MATERIALS INVESTIGATIONS We will analyze bed and bank sample data at severe bank erosion sites. Additional subsurface ex- plorations will be made in salt intrusion area near Salina. An electrical resistivity study will be made to better define salt intrusion sources and patterns. Preliminary investigations of geologic and soils condi- tions at water supply lake sites and pipeline corridors will be made. SUBACCOUNT 11, DESIGN AND COST ESTIMATES Activities will include design and cost data for final array of plans at severe erosion sites. For water supply, a review of contractor-supplied design and cost data for water supply lake sites and pipelines will be made, and detailed cost estimates for reallocation and alternative projects, including single- purpose lakes, will be made. Design and cost estimates for portions of salt intrusion reduction plans, such as pipelines, evaporation ponds, and low dams, will be prepared. SUBACCOUNT 12, REAL ESTATE STUDIES Estimation of real estate requirements for alternative plans at severe bank erosion sites, including rights-of-way, easements, and fee acquisition will be accomplished. Ownerships will be identified in the salt intrusion area near Salina and obtain rights-of-entry where needed for additional surveys and drilling. SUBACCOUNT 13, STUDY MANAGEMENT • This will include review of progress of the study, revision and updating of the schedule where necessary, and obtaining input from Federal-State Coordinating Committee. It will include a decision regarding possible preparation of one or more interim reports during stage 2. • SUBACCOUNT 14, PLAN FORMULATION This task includes refinement of bank stabilization alternative plans and assessment for possible inclusion in stage 3 studies. We will prepare intermediate plans for water supply and salt intrusion, including one or more lake reallocation plans at each of four lakes, and one or more nonstructural (con- servation) plans for each major area of water supply need. A series of structural and combination plans will be developed, with emphasis on plans which combine the more easily implementable conservation . measures with other measures. SUBACCOUNT 15, REPORT PREPARATION A Stage 2 Documentation Report for all study purposes will be prepared. If studies so indicate, one or more interim reports for urgently-needed plans will be prepared. SUBACCOUNT 20.1, WATER SUPPLY Studies will be conducted by contract to screen a large number of alternative water supply measures and to narrow down to a reasonable number of alternatives. The MAPS (Methodology for • • Area-Wide Planning Studies) developed by the Corps' Waterways Experiment Station will also be used for this work. Data collection on water use by sector will be accomplished. E-3 SUBACCOUNT 20.2, WATER QUALITY Studies will be conducted by contract and by other agencies to supplement existing and KCD-gen- erated water quality data and to model salt intrusion. Mathematical models will be used to simulate historic conditions and to assess alternative measures to reduce salt intrusion in the Salina area. • SUBACCOUNT 20.4, CAUSE AND EFFECT ANALYSIS Studies will continue by contract with the University of Kansas Geology Department to attempt to identify cause and effect relationships for bank erosion. Additional inhouse studies will be performed to examine possible effects of lake operation. SUBACCOUNT 20.9, RECREATION STUDIES • The HCRS will continue to evaluate the recreation potential along severe erosion sites, with emphasis on the Kansas River between Lawrence and Kansas City, Kansas.
