<br />4. Cultural Resources. <br /> <br />a. National Historic Preservation Act of 1966. <br /> <br />b. Archeological and Historic Preservation Act of 1974. <br /> <br />c. Executive Order No. 11593, Protection and Enhancement of the Cultural Environment, <br />May 13, 1971. <br /> <br />The proposed project is expected to impact the cultural resources of the area. To ensure that <br />significant cultural resources would not be adversely affected, a cultural resource reconnais- <br />sance study was completed in 1975. This survey was undertaken 'on approximately 80 percent of <br />the Narrows study area. The unsurveyed area wi 11 be done prior to any project construct ion. <br />The remaining archeological and historical compliance steps as outlined in 36 CFR 800 would be <br />undertaken, including consultation with the Advisory Council on Historic Preservation. <br /> <br />5. Executive Order No. 11990, Protection of Wetlands. This executive order requires each <br />agency to minimize adverse effects on wetlands. All practical efforts would be undertaken to <br />meet thIs objective, However, wetlands adjacent to the river channel would be inundated and <br />essentially lost, but In other areas, wetlands would be established due to seepage and low- <br />lyin9 pockets of trapped water during drawdown. The intensive wildlife management plan would <br />impound 540 acres (219 ha) of open-water marsh. Also, a 13,189-acre (5,340-ha) reservoir <br />would be created. <br /> <br />'.1 <br /> <br />6. Executive Order No. 11988, Flood Plain Management. This executive order requires Federal <br />agencies to avoid the adverse impacts of occuPYIng and modifying flood plains to reduce flood <br />losses and to preserve theriatural and beneficial values of flood plains. The flood plain <br />within the conservation pool would be lost for all practical purposes. However, due to land <br />aquisition adjacent to the proposed reservoir, construction is not expected to directly <br />support flood plain development. <br /> <br />7. Fish and Wildlife Coordination Act of 1958. The Coordination Act provides that fish and <br />wildlife conservation shall receive equal consideration with other project purposes and be <br />coordinated with the Fish and Wildlife Service and the appropriate state fish and wildlife <br />conservation agencies. <br /> <br />The Narrows Unit Reservoir study has been actively coordinated with the Fish and Wildl ife <br />Service dated June 1983 (see appendix B), the Colorado Division of Wildlife, and the Nebraska <br />Game and Parks Commission. These agencies have actively participated in the determination of <br />fish and wildlife conservation plan, in particular for waterfowl, upland game, the mitigation <br />process, ,and the establishment of wildlife management areas. <br /> <br />Until such time that an implementable plan is developed from the existing plan of study (appen- <br />dix 0) to relieve the jeopardy opinion on the whooping crane in central Nebraska, the extent, <br />if any, for desired mitigiltion measures of the other Nebraska wildl ife resources, will remain <br />undetermined, Once the extent of the measures needed to relieve the jeopardy opinion on the <br />whooping crane are ascertained, mitigation for other species will be considered if they are <br />negatively impacted. Additionally, if the plan of study for endangered species resolutIon and <br />downstream miti9ation results in materi al changes in project impacts and/or feasibil ity, the <br />appropriate documentation will be prep~ed. <br /> <br />$-5 <br /> <br />I <br />I <br />
