Flood control storage capacity at Narrows Reser- voir will be reduced, and the Union Pacific Railroad will be relocated around the south side of the project as previously planned. These deciBions were reached as part of preconstruction activities started earlier this year. Activity was resumed in response to the House Appropriations Committee which directed that "With available funds, the Bureau of Reclamation should conduct appraisal work and final design work on the Narrows Unit, Colorado, to ready the project for construction." A second addendum to the DPR (Definite Plan Report) is now being prepared and is scheduled to be completed during fall 1983. It will contain the updated project plan and economic and financial data. Flood Control Storage The flood control pool will be reduced from 475,000 acre-feet to 233,000 acre-feet. The 75,000 acre-foot joint-use pool will also be eliminated. The reduc- tion in space will regulate a flood estimated to have a reoccurrence interval of once every 25 years instead of every 100 years as propoBed in the 1976 plan. By regulating the 25-year flood, the project will achieve most of the benefits associated with regulating the 100-year flood. Effect of these changes on project cost is unknown. Updated cost estimates will be contained in the, addendum to the DPR Although the flood control pool has been reduced, the dam and spillways will be designed to accommodate the maximum probable flood. . Narrows Unit Colorado No. 2 December 1982 Railroad Relocation The Union Pacific Railroad will be relocated around the south side of the Narrows Reservoir as described in the 1976 plan. The railroad currently closely follows the north bank of the South Platte River through the reservoir area. The relocation will involve construction of about 26 miles of new track. Major structures will include two bridges over the South Platte-one below the dam and another where the track recrosses the river at the west end. A bridge also will be built. over Kiowa Creek and two underpasseB con. structed for existing State Highway 144. Other Actions Reclamation will purchase land around the top of the conservation pool in 10-acre inste9d of 40-acre blocks. Easements granting the right to inundate land will also be sought in lieu of purchasing land outright. ....."..,"" Determination of municipal and industrial water needs will be made this winter.
