'~.~l.~, ,_ .. I I I ~R 3. WATER MANAGEMENT PLAN I 5. Financing plan to complete improvements I 6. Evaluation of operation, maintenance, and environm~ntal concerns I The NFWCD would require financial assistance to complete this J.,ork; however, it has been identified as a high priority issue. I i Conduct Feasibility Study to Evaluate Removal 'of Silt From Paonia Reservoir Loss of storage capacity in Paonia Reservoir is estimated at 100 acre-feet each year. Sedimentation has resulted in a loss of over 4,400 acre-feet since filling the reservoir in 1962. At this rate, the sediment pool will be fully depleted by the year 2007. The NFWCD would like to examine the feasibility of increasing storage in Paonia Reservoir by removing sediment. Can sediment be removed at a cost-effective rate, by dredging or other method, and still meet permitting requirements? Additional storage would provide additional drought season or late season water. The feasibility study would examine sediment removal methods, removal rates, estimate costs and benefits, permitting requirements, and environmental concerns. The study would recommended a preferred alternative in additional to reviewing a no action alternative. Begin Infrastructure Replacement Program for Leroux Creek System As with many of the irrigation systems in the NFWCD, the Leroux Creek area is seeing deterioration of their irrigation infrastructure. Rehabilitation is needed for diversion s~ructures, canal gates, water measuring devices, and delivery canals. The NFWCD would like to pursue alternative water pricing structures and grant opportunities to assist with 'infrastructure replacement. This would involve maintaining ongoing discussions with irrigation companies and other sources to identify funding opportunities. The NFWCD would pursue funding and project implementation as opportunities arise. Develop Cleaning Vault Design for Siphons Currently, the FMCC has no safe and effective way to clean debris from existing siphons. Existing cleaning vaults are old and inoperable. The FMCC would like to examine alternative designs that would improve the ability to maintain existing siphons. Designs that have been considered include placing 4-foot diameter cleaning hatches at the base of siphons with concrete vaults. In addition, trash rack alternatives would be considered that blocks debris from entering siphons, improve safety, but does not encourage debris jams. With assistance from USBOR engineering staff, FMCC would select a feasible design and examine funding alternatives to implement siphon improvements. Actively Participate in Streamflow Negotiations The U.S. National Park Service (USNPS) is currently attempting to quantify water rights within Black Canyon National Park. Water rights were decreed in 1933; ~owever, a specific amount was never appropriated. In addition, the U.S. Fish and Wildlife Service (USFY'JS) is examining alternatives to improve the recovery of endangered fishes in the lower Gunnison River qasin. These activities could affect water use in the NFWCD. The NFWCD would like to maintain an activ,e role in these water-related negotiations to ensure the District's interests are not jeopardized. Continue FMCC Infrastructure Replacement Program Currently, the FMCC allocates over 20 percent of their annual budget to capital improvements. This allows FMCC to replace and improve aging infrastructure at a modest pace. However, additional improvement projects have been identified that require attention. These projects include the following: 3-5 I- I ~) 'I I I I I I I 01 I I I I I I I :]1 I
