STATEMENT OF FINDINGS CARLYLE LAKE ILLINOIS I have reviewed, in light of the overall public interest, the operation and maintenance program at Carlyle Lake, Illinois, relative to the various practicable methods of carrying out its authorized^ purposes of flood control, navigation, domestic and industrial water supply, fish and wildlife conservation and recreation. I have considered the comments of all interested parties in response to the draft environ mental impact statement issued in August 1973. : In my review of this lake's operation and maintenance program, I have found that Carlyle Lake has helped to reduce downstream flooding on the Kaskaskia River. This was especially true during the severe spring floods of 1973 when flood crests were reduced as much as 5. 8 feet at Posey, Illinois. During 1974, the Kaskaskia Navigation Project will open and Carlyle Lake will help to assure that its nine-foot minimum channel can be maintained during drought periods. My investigations have found that Carlyle Lake provides a large permanent warm water fishery while wildlife management programs carried on by the State of . Illinois' Conservation Department and Corps of Engineers' personnel have made this lake one of the most successful migratory bird areas in the State of Illinois. Recreation facilities have been provided for a multitude of outdoor activities ranging from areas where one may hunt to camping areas with hot showers. These facilities, combined with the basic land and water resources of Carlyle Lake, attracted over 2, 500, 000 visitors in 1973. I have noted and carefully considered the adverse environmental impacts which have resulted or will result from the operation and maintenance program at Carlyle Lake. Lake regulation for the purpose of flood con trol has and will cause many periods of high water and fluctuating water levels. These high waters and fluctuating water levels have and will continue to cause severe shoreline erosion, the destruction of shoreline vegetation, the interference with normal fish spawning and the disrup tion of recreation activities on both land and water. I also recognize that the use of riprap for the purpose of shoreline protection has the effect of reducing the natural aesthetics of the lake shoreline. Other impacts of a less significant nature are recognized in the environmental impact statement. I believe that all appropriate steps were taken in the preparation and presentation of the environmental impact statement to disclose fully all known environmental issues. All pertinent facts have been presented, studied, and discussed by appropriate professional personnel on my staff. : I believe the environmental impact statement complies, with / . the spirit of the National Environmental Policy Act of 1969. Alternatives to the present operation and maintenance program have been studied according to environmental, social and economic effects including regional development and engineering feasibility. Alter natives considered included revised regulation plans and methods of shoreline protection. Therefore, being appraised of the environmental, social and economic losses and gains that have and will accrue from the operation and maintenance program at Carlyle Lake and having considered the practicable alternatives in the light of economic and environmental factors, social well-being and engineering feasibility, I have con cluded that, on balance, the effects of the operation and maintenance program at Carlyle Lake are beneficial and that it is in the best public interest that they be continued.

Description of Action: Operation and Maintenance of a Multi-Pupose Reservoir in Clinton,.Fayette and Bond Counties, Illinois. 3. Environmental Impacts and Effects: a. Environmental impacts - The Carlyle Lake Project provides flood control, water quality control by low-flow augmentation, navigation, industrial and domestic water supply and recreation benefits as well as certain other economic benefits within the area arising from employment and investment opportunities. The Lake provides a large permanent warm-water fishery while adjacent public lands are intensively managed for wildlife. The total magnitude of public use as expressed in visitors per day have increased greatly. Variable water levels due to flood control activities have damaged or destroyed vegetition at lower elevations while severe shoreline erosion has occurred due to wave action. b. Adverse environmental effects - Conflict of use due to fluctuating water levels; shoreline erosion from wave action. 4. Alte rnatives: Revised regulation plans, shoreL'ne protection. 5.
