project would protect about 15,620 acres of agricultural land against a flood which could be expected to have an average occurrence of 7 times in a 100-year period. Monroe Reservoir The Monroe Reservoir project was authorized by Congress and approved by President Eisenhower in July 1958. A report was published in January 1957, as the result of joint studies by the Indiana Flood Control and Water Resources Commission and the Corps of Engineers, U.S. Army, establishing the feasibility of the project for both flood control and low-flow augmentation. The project was approved by the 1957 Indiana General Assembly. Congress voted $25,000 to the Corps of Engineers for the fiscal year 1958-59 for start of final designs and construction planning. An additional amount of $73,125 is available in fiscal 1960. The Indiana General Assembly has voted $1 million as first amount in the State's share of total cost. The reservoir would be formed by a dam located on Salt Creek east of Harrodsburg, Ind. The outlet works would include an uncontrolled saddle spillway and control sluices through the dam. It would control a drainage area of 441 square miles, and have capacity corresponding to 19 inches of runoff from that area. The reservoir will have the following capacities and surface areas: Area subject to temporary flooding (18,500 minus 10,700). acres__ 7,800 Area subject to temporary exposure from 5-foot drawdowns for water supply-‒‒‒‒ Storage allocated to flood control___ __acres____ 1,800 ---acre-feet-- 260,000 do---- 159, 000 do--- 27, 000 Storage allocated for increasing low flows is sufficient to maintain a minimum flow on East Fork White River at Shoals at 500 cubic feet per second; en White River at Petersburg at 1,400 cubic feet per second during summer months and 1,000 cubic feet per second during winter months. Flood control, future water supplies, low-flow benefits in improved water quality to downstream stretches of Salt Creek and White River and recreational benefits would be derived. This is a joint project of the Federal Government (through the U.S. Army Corps of Engineers), and the State of Indiana (through the Indiana Flood Control and Water Resources Commission). Under present Federal law, only flood control benefits may be counted for the Federal share of costs. Engineers of the U.S. Army Corps of Engineers and engineers of the Indiana Flood Control and Water Resources Commission found that best use would be attained by providing for a pool of about 11,000 acres, with storage space for flood flows above that elevation in heavy rainfall seasons and with provisions for releases through a conduit in the base of the dam to be made for reinforcing the downstream volumes in dry periods. To btain maximum results in his plan, the engineers computed flood control beneits as 45.9 percent of total cost and other non-Federal benefits as 54.1 percent of total cost. The State of Indiana, through the 1957 general assembly, authorized the projects as valuable for the future economic growth of the State. The State at provide funds to assure the meeting of non-Federal costs, 54.1 percent of total. Non-Federal funds for any one phase of the project must be in the tands of the Corps of Engineers before the corps can let contracts for that phase. Salamonie Reservoir (upper Wabash system) would be formed by an earth dam located on Salamonie River 3.5 miles above its mouth at the Wabash River. It would control a drainage area of 522 square miles. Outlet works would include a broad-crested, ungated, saddle spillway through the divide between the Salamonie and Wabash valleys, and controlled sluices through the dam. The dam would rise about 128 feet above streambed to top elevation 812 feet above mean sea level. The spillway crest would be at elevation 791 and, under maximum storage conditions, the flood control pool would reach elevation 806. At the latter elevation, the reservoir pool would have an area of 19,230 acres, and would extend upstream to about river mile 30. A permanent pool would be provided with surface area of 950 acres at elevation 730. A sum of $146,250 is in fiscal 1960 budget. West Terre Haute local protection project (Louisville district): Located on the right bank of the Wabash River in Vigo County, the project would afford protection of the city of West Terre Haute, Ind., against a flood equal in magnitude to that of March 1913, the maximum of record. It would consist of an earth levee with traffic ramps and sewage and internal drainage disposal facilities. Sugar Creek levee (Vigo County): This project is located on the right (west) bank of the Wabash River opposite Terre Haute, Ind. It would consist of about 3.9 miles of earth levee and other necessary appurtenances, extending from U.S. Route 40 southwesterly along Wabash River to the mouth of Sugar Creek and thence northwesterly along Sugar Creek to high ground at U.S. Route 40. The levee would provide protection against a flood which will be equaled or exceeded seven times in each 100 years on the average. Mississinewa Reservoir (upper Wabash system), to be situated in Miami, Wabash and Grant Counties, Ind., would be formed by an earth dam located on Mississinewa River, 7.1 miles above its mouth at the Wabash River. It would control a drainage area of 801 square miles. Outlet works would include a broad-crested, ungated, saddle spillway through the divide between the Mississinewa and Wabash Valleys, and controlled sluices through the dam. The dam would rise about 137 feet above streambed to top elevation 797 feet above mean sea level. The spillway crest would be at elevation 779 and, under maximum storage conditions, the flood-control pool would reach elevation 790. At the latter elevation, the reservoir pool would have an area of 17,170 acres. and would extend upstream to about river mile 35. A permanent pool would be provided with surface area of 1,300 acres at elevation 712. A sum of $146,250 is in fiscal 1960 budget. Huntington Reservoir (upper Wabash system), to be situated in Huntington and Wells Counties, Ind., would be formed by a dam located on Wabash River near Huntington, Ind. The structure would consist of an earth embankment with gated concrete spillway section, and would control a drainage area of 708 square miles. Controlled sluices would be provided through the concrete section of the dam, which would rise about 90 feet above streambed to top elevation 805 feet above mean sea level. Under maximum storage conditions, the floodcontrol pool would reach elevation 797, at which level it would have an area of 7,840 acres and woul extend upstream about 23 miles to Bluffton, Ind. A permanent pool is not contemplated, under the original plans. A sum of $24,375 is in fiscal 1960 budget. Functioning as a system, the proposed three reservoirs of the upper Wabash system would effect reductions of the following order in the crest stages of such great floods as those experienced in 1913, 1943, and 1950. Levee unit 5, Wabash River (Louisville district) The project area is bounded, generally, on the north by the Patoka River, a tributary of the Wabash River; on the west and south by the Wabash River; and on the east by the Black River, another tributary of the Wabash River. Located opposite and below Mount Carmel, Ill., in Gibson and Posey Counties, Ind., the project would include a system of earth levees with traffic ramps and internal drainage facilities. It would also include alterations of three railroad bridges which would be affected by the project. The project would afford protection to a 43,200-acre agricultural area and the communities of Griffith, Skelton, and Lyles, against a flood which could be expected to occur on an average of 7 times in a 100-year period. Ohio River Basin INVESTIGATIONS AND SURVEYS The constant reevaluation of flood-control progress is in the best interest of the people of the United States. The Ohio River Basin, one of the great industrial and agricultural areas of the world, has been the site of many Corps of Engineers projects in the last two decades. Up-to-date computations on their effectiveness are essential for continued advancement of these works on a sound basis. Wabash River above White River— These reservoir surveys are included in this program. Big Pine Creek Reservoir The Big Pine Creek Reservoir is one of several sites being studied to control foods in the Wabash River Basin. The reservoir would control runoff from Big Pine Creek and help reduce flood stages on the main Wabash River. Field surveys have been made by State commission personnel since 1956. Topographic maps were completed by the commission in April 1958. An areacapacity study of a damsite near State Road 55 was completed in April 1958, using these maps. Geologic and geophysical investigations were made of the reservoir area by the commission's geologist and the engineering geology division, school of civil engineering, at Purdue. A preliminary report of these investigations was completed in April 1958. All of this work is part of a cooperative effort between the commission and the Louisville District Corps of Engineers. The results of the work accomplished by the commission will enable the Corps of Engineers to proceed at a faster pace in the making of the Pine Creek site. The Corps of Engineers studies include such things as hydrologic and hydraulic investigations; investigation of flood damages and flooding frequencies; costs of construction of a project; and the benefits to be derived from construction of a reservoir at this site. Wildcat Creek Reservoir Wildcat Reservoir site is on Wildcat Creek near Lafayette. It is one of a group of reservoir sites being studied by the commission and the Corps of Engineers in the development of a flood-control plan for the Wabash River Basin. Field surveys for mapping of this reservoir have been made by commission personnel. Topographic maps, based upon these surveys, were completed by the commission in 1955. In 1957, at the request of the Corps of Engineers, additional field surveys were made to extend the topographic coverage. The revised topographic maps were completed in April 1958. Geologic and geophysical investigations were made by the commission geologist and the engineering geology division, school of civil engineering, at Purdue University, and preliminary report covering these investigations has been prepared. The Corps of Engineers studies include hydrologic and hydraulic investigations of flood damages and flooding frequencies; costs of construction of a project; and benefits to be derived from construction of a reservoir at this site. Bugar Creek at Turkey Run A reservoir on Sugar Creek, with a dam located upstream from Turkey Run State Park and with a pool to extend to Shades State Park has been proposed. The proposed reservoir would include a dam near the bridge at the east edge of Turkey Run State Park. Reservoir storage would extend upstream nearly to Crawfordsville at times of extreme floods. Water elevation most of the year would be about as it is now in the gorge throughout Shades Park. The reservoir would control 692 of the 840 square miles of drainage area in the Sugar Creek watershed. Further studies are necessary to determine feasibility. White River Basin (East Fork) The commission was directed by the legislature to make engineering, economic and geologic investigations and surveys for flood control and water resource development in the East Fork of White River Basin with emphasis on the prot lems in the Muscatatuck River Basin. For the East Fork of White River Basin as a whole the commission is in th process of completing a network of vertical controls on all the major tributar streams so that elevations can be determined for the high-water marks that hav been established for various past floods. This information is one of the mos necessary elements needed in determining the extent of flooding in relationshi to quantities of water that are involved in various size floods. The commissio has marked flood heights for high waters in recent years throughout most of th watershed. In the Muscatatuck River Basin investigations have been made for fou possible reservoir sites on Big Graham Creek, Big Creek, and the Muscatatue River. The area and capacity of each of the considered sites has been deter mined and the Indiana Geological Survey has made a preliminary report o ngineering geology of the reservoir areas. White River Basin (West Fork) A program has been set up to run precise levels and establish sea level elevs tions for high-water marks on the West Fork of White River from its junctio with the East Fork to its headwaters. This work is preliminary to the studie of the effects of present and proposed levee projects along the stream. The Corps of Engineers and the State commission are cooperating in thes surveys. Whitewater River Basin As the result of the severe flooding along the Whitewater River from Brook ville to West Harrison in January 1959, considerable public interest has bee shown in the Brookville Reservoir site. This project was authorized by th U.S. Congress in the Flood Control Act of June 28, 1938, but, due to a lack local interest, it had been dormant until 1959. This reservoir would be operated as a unit of a reservoir system to contr flooding in the Whitewater and Ohio River Valleys. The dam site is locate on the East Fork of the Whitewater River about 2.4 miles upstream from it corfluence with the West Fork of the Whitewater River at Brookville, Ind. A resurvey will be needed, due to the long period of time that has elapse since the project was authorized in 1938. In future studies, consideration should be given to low flow augmentation and water supply, in addition to floo control needs. Preliminary studies by the Corps of Engineers prior to 1938 indicate tha an earthfill dam, 115 feet high, could be constructed to form a reservoir with a storage capacity of 150,000 acre-feet for temporary storage of floodwaters. Since design studies have not been made, accurate information is not available as t elevations for permanent pool and maximum flood pool. Kankakee and Yellow Rivers Basin Since the summer of 1955, the State commission and the Corps of Engineers have cooperated in investigations and studies of the flood problems and majo drainage needs of the Knkakee and Yellow Rivers Basin. Since neither avail able funds nor personnel were sufficient to conduct a concurrent study of the entire basin, the studies were divided into three units as follows: (1) the Yellow River, (2) the Kankakee River above English Lake, and (3) the Kankakee River between English Lake and the Illinois-Indiana State line. Work on the first unit, Yellow River, has been completed, hydrologic and hydraulic studies were made by the commission and Corps of Engineers to determine the size of channels required to handle flood discharges and the reduction of flood stages that could be obtained by providing better flow conditions for Yellow River. Studies were made of flood damages, streamflows, and flood frequencies to arrive at estimates of the benefits that would accrue if a proiect were constructed. The U.S. Soil Conservation Service made studies of the present and future drainage needs in the Kankakee and Yellow Rivers Basin. The Water Resources Division of the U.S. Geological Survey has cooperated in the collection of basin data for this work through the operation of a number of stream gages in the basin. Work on the upper Kankakee River above English Lake is underway. Flood damage surveys have been made along the Kankakee River in Stark and La Porte Counties and will be extended into St. Joseph County. Mapping of the areas subject to flooding is in progress. This work is being continued and extended as funds are available. Little Calumet River Basin The current authorization provides for a review of previous reports to determine the advisability of providing improvements for flood control on Little Calumet River and tributaries, Illinois and Indiana. An extremely serious flood hazard exists in the basin, particularly in the Indiana portion thereof, because of the unprecedented development of the flood plain for residential and other purposes within the past few years. No funds have as yet been made available to the corps to initiate the investigation of these serious problems. Such funds are urgently needed because of the definite flood hazard and because of the continuing exercise in property values of the lands on which the necessary works of improvement must be constructed. Yaumee River Basin The Corps of Engineers, U.S. Army, Detroit district, has been making a study of the flooding potential of the St. Marys, St. Joseph, and Maumee Rivers through Fort Wayne and downstream. There is a serious flooding danger in Fort Wayne and the rapid expansion of suburban housing and industries threatens to encroach upon the flood plain and aggravate the situation. Funds are needed to complete the survey by the corps and to begin the preparation of detailed plans for the protection of these vital areas. Further delay will greatly ncrease the cost of protection, because of the rapid increase in value of the properties on which the protective works will need to be constructed. Chicago metropolitan area, including parts of Lake County, Ind. The purpose of the survey is to investigate the complex of flood and major drainage problems in the Chicago metropolitan area, which includes parts of Lake County, Ind. By reason of the tremendous economic development of this area, the low, flat nature of the terrain and the poorly developed drainage systems, the problems are complex, interrelated and of broader scope than the jurisdictioned limits of local governmental units. Funds are needed to permit 60mprehensive and integrated study so as to determine the most feasible overall lution to these problems. Comprehensive survey report on water levels of Great Lakes The purpose of the survey is to determine the feasibility of a plan of regulation of the levels of the Great Lakes in the interest of navigation, power, and the alleviation of shore erosion, and to determine the advisibility of local protection projects along the shores of the Great Lakes and tributary stream for those areas subject to inundation from fluctuations in lake levels. The extraordinary property damages sustained from high lake levels in 1951-52 and the vast and teadily increasing importance of navigation and power on the Great Lakes ystem are evidence of the need for a system of control. Funds are needed to permit the investigation to continue on an orderly and systematic basis. NAVIGATION PROJECTS AND PLANNING Markland locks and dam The Markland locks and dam is one unit in the authorized overall replacement and modernization program for the Ohio River navigation system, and is loated 531.5 miles below Pittsburgh, near Markland, Ind. It will replace five of the existing locks and dams. The project consists of a gated dam and two locks, one 110 by 600 feet and the other 110 by 1,200 feet, with a maximum lift of 35 feet. Construction is far advanced. Lock and dum 41 (Louisville) The project is a unit in the authorized overall replacement and modernization gram for Ohio River navigation. It consists of the improvement and partial reconstruction of navigation facilities at locks and dam 41, located on the Ohio River at Louisville, Ky. Details of the work include the modification of the existing dam, the construction of a new lock, 110 by 1,200 feet, and widening of the upper approach level to the locks. Construction of the project began in May 1958 and is well advanced. |
