Specific land requirements fo~h and wiIdllfe and recreation purposes have not yet been deter- mined. Some portion of these land requirements would be in addition to the lands acquired around the top of the conservation pool. Total land required for the project is now expected to be less than the 1976 estimate of 42,000 acres. A review of hydrologic data was conducted earlier this year. Analyses of updated information based on longer term record8 resulted in a minor reduction in the estimated average annual yield of water from the project. Other contributing factors to the reduction include revised evaporation rate estimates and the elimination of the joint-use pool. The average annual yield is now estimated at 96,400 acre.feet as compared with an earlier estimate of 102,000 acre.feet. Other items .Pleted as part of preconstruction activity include geologic drilling and mapping along- the damsite to provide additional founda. tion information for the designers and test pits dug to determine suitability of material available for construction of the dam. Reclamation is consulting with several State and Federal agencies concerning various aspects of the Narrows Unit. These include Colorado Division of Parks and Outdoor Recreation and National Park Service concerning recreation plans; the Colorado Division of Wildlife and U.S. Fish and Wildlife Service concerning fish and wildlife issues; Colorado Division of Highways concerning reloca- tion of roads within the project area; and the Army Corps of Engineers concerning flood control issues. State officials from Nebraska and Colorado Map shows the revised maximum water surface eleva. tioD of Narrows Reservoir-a result of a reduction in flood control storage capacity. Proposed Union Pacific Railroad relocation is also shown. .. ,..~'u .is,';.vol. ,.;:' , , $ , i ~ V'--;J r I . I ( . H_ &". . ~ "%
