FINAL ENVIRONMENTAL STATEMENT HUOO LAKE KIAMICHI RIVER, OKLAHOMA Prepared by TULSA DISTRICT, CORPS OF ENC,INKERS TULSA, OKLAHOMA February 1974 Statement of Findings Hugo Lake, Kiamichi River Basin, Oklahoma As Acting District Engineer, Tulsa District, Corps of Engineers, it is my duty in the role of responsible Federal Official to evaluate project data presented in the environmental statement, draw conclusions, and make recommendations to my higher authority. The overall public interest has been given the utmost consideration and personal concern in my review and evaluation of the documents concerning the proposed action, as well as the stated views of other interested agencies and the public, relative to the various alternatives in accomplishing the purposes of flood con­ trol, water supply, recreation, and fish and wildlife. Therefore, I have both a professional and personal concern in drawing the soundest possible conclusions from the studies, observations, and consultations made in the investigation of Hugo Lake. Project formulation studies for Hugo Lake occurred prior to the passage of the National Environmental Policy Act. During those studies public meetings, informal meetings, and workshops were conducted within the project area to determine public preferences, opinions, needs, and objectives. All project-related information derived from these meetings was carefully evaluated during plan formulation and was incorporated into the planning ana development of Hugo Lake for the total public interest. The construction of the project was 83 percent complete on 31 October 1973. A draft environmental statement was completed and released for review by other agencies, groups, and individuals on 21 September 1973. The final statement was then prepared utilizing comments received on the draft statement, technical assistance from the University of Oklahoma, and additional environmental studies by the Corps of Engineers. All correspondence received on the draft has been considered in the final environmental statement. All reasonable alternatives were considered or reconsidered in the preparation of the statement. The ones which merited the most serious consideration were the authorized (under construction) project, a dry lake at the authorized damsite, and abandonment of the project. These alternatives were assessed by a multidisciplined professional group. Each alternative was studied with regard to impacts on the natural environment, social well being, and economics, including regional and national development and engineering feasibility. Detailed studies of the alternatives revealed that only the authorized project xjould fulfill all of the project purposes. The dry lake plan would provide about the same degree of flood protection, buc would not provide water supply, fish and wildlife, and recreation benefits. The cost involved to abandon the project and the benefits that would be foregone indicate that the alternative to abandon the project is not feasible. Other factors bearing on my review include the under construction status of the project vr>cn the ”"’tiw>.l Environmental Policy Act became effective and the alternatives studied prior to the Act. I have given careful consideration to the plan to mitigate wildlife losses. The plan to establish a National Wildlife Refuge and a State Game Management area is well conceived and in consonance with national objectives. Other recommendations of the Bureau of Sport Fisheries and Wildlife concerning fisheries management have been included in develop­ ment plans. I therefore conclude that although some alternatives would.have more favorable impacts in some areas, Hugo Lake will most adequately fulfill the social, economic, and other requirements of the present and future generations of Americans. After consideration of the data contained in the environmental statement, I find that in the proposed action, when adverse effects are found to be involved, those effects are either ameliorated or substantially outweighed by other considerations of national policy; that the recommended action is consonant with national policy, statutes, and administrative directives; and that on balance the total public interest is best served by construction and operation of Hugo Lake. 20 Mar 74______ W.

Name of Action; Construction and operation of Hugo Lake, Oklahoma. ( X ) Administrative. ( ) Legislative 2. Description of action. The project is located in Choctaw County just west of the town of Sawyer, Oklahoma, on the Klamichl River at river mile 17.6. The action consists of construction and operation of a lake for flood control, water supply, water quality control, recreation, and fish and wildlife management. Construction was 7A7. complete as of 1 January 1973. 3. Environmental Impacts. a. Completion of the proposed project will significantly reduce annual flood damages and will provide for water supply, water quality control', recreation, and fish and wildlife management. The high quality water supply will meet the 50-year water needs of the Hugo-Antlers area. Expanding industrial development and rising population trends in metropolitan areas outside the Klamichl River basin, but within reasonable water transmission distance emphasize the need for additional water supply. Prolonged drought periods in the project area show the need for providing conservation storage of surface runoff to meet the demands for water supply and water quality control. Low-flow augmentation will enhance the downstream environmental setting by providing a more stable and constant flow of higher quality water. The lake would provide a recreational resource situated in scenic surroundings and readily available to growing urban areas. The project will result, in an Increased fishery while approximately 13,250 acres of land and the vegetation it supports will be inundated. Additional changes will occur from project construction, operation, and human disturbance. b. Adverse environmental effects. The conservation pool will permanently inundate 13,250 acres of land, Including approximately 35 miles of Klamichl River. This land and stream provided habitat for fish and wildlife. An additional 21,2A0 acres wili be periodically Inundated during flood time. The project has displaced 68 families. Three state highways, several county roads, pipelines, powerlines, telephone lines, and approximately 100 graves are being relocated.
