The major assumptions used to project long-term expenditures for each of several categories established by the Board are listed below: . Compact Entitlement through New Storage - Objective 1 of Goal 2 ofthe Board's Long Range Plan is to "enhance water supplies and develop Colorado's compact allocations," In 1993, the State Engineer identified 36 dams on the western slope which could be enlarged by a total addition of approximately 166,000 acre-feet (see Appendix D). Assuming an average cost of$I,OOO per acre-foot to enlarge these reservoirs, the total cost is estimated at $166,0 million. Assuming loans will be made at 75-percent of the total cost over the next 10 years, future expenditures for new storage could be as high as $124.5 million, or an average of about $12.0 million per year. Objective 2 of Goal 2 of the Long Range Plan is to promote "specific projects" including the Animas-La Plata Project, enlargement of Elkhead Reservoir, and a reformulated San Miguel Project. It has since been determined that enlargement of Elkhead Reservoir will not be funded through the Construction Fund, although the City of Craig may use their 10an authorization to rehabilitate the spillway, Other specific projects identified from our future prospects lists and a statewide needs survey of water users in 1993 were also included in the projection as an indication of potential future water resources projects. Loans for futurt' unspecified feasibility studies will be estimated at $200,000 per year. . Compact Entitlement through Dam Rehabilitation - Objective 5 of Goal 2 ofthe Long Range Plan is for the "rehabilitation of restricted storage capacity." The State Engineer has restricted storage in 188 reservoirs in Colorado for dam safety pmposes (see Appendix D). The total volume currently restricted is 132,795 acre-feet with 24% in the South Platte River basin, 62% in the Arkansas River basin, 7% in the Rio Grande basin, and 7% on the westem slope. Assuming an average cost of$1,500 per acre-foot to fix these dams, the total cost is estimated at $199.2 million. Assuming loans will be made at 75-percent of the total cost over the next 10 years, future expenditures for dam rehabilitation could be as high as $149,4 million, or an average of about $15.0 million per year, A . Water Resources Infrastructure - Objective 6 of Goal 2 of the Long Range Plan is to "rehabilitate existing infrastructure." Future rehabilitation of water resources infrastructure such as diversion structures, pipelines, headgates, canals, ditches, and other raw water collection and delivery facilities will be estimated at up to $5.0 million in loans per year.
