It is essentially the same as Alternative 3 except for the size of the <br />Ulylands Reservoir enlargement. <br /> <br />Alternative 6 would provide additional irrigation water supplies for all three areas, both by <br />developing new sources of supply and by improvements and expansions of existing facilities, It <br />is essentially a combination of the features comprising Alternatives 1, 4 and 5 and is <br />comparable to the High Elevation System recommended in the 1985 "Reconnaissance Report <br />for the San Miguel Project Rescoping Study", The additional storage would be provided by a <br />new reservoir at the Marie Scott site on Saltado Creek (capacity of 15,000 af) and enlargement <br />of both the existing Lone Cone and Ulylands Reservoirs to capacities of 5,800 af and 6,500 af, <br />respectively, <br /> <br />In addition to the features incorporated in the six alternative project configurations, Radium <br />Reservoir and the San Miguel Canyon Project are proposed as optional features of the San <br />Miguel Project, Radium Reservoir could be constructed in the Dry Creek Basin and operated <br />as a wildlife habitat and recreational facility, The San Miguel Canyon Project is a potential <br />pumped-storage hydropower facility located in the San Miguel Canyon three miles northeast of <br />Norwood, This optional project feature would be a revenue-producing facility which could <br />potentially also provide additional irrigation water to the Norwood-Redvale area, <br /> <br />Evaluation of Alternatives <br /> <br />The six project alternatives were evaluated at a reconnaissance level of detail using the <br />estimated reliable water yields of each alternative and the estimated costs of constructing and <br />operating the alternative project systems, The cost estimates are based on April 1988 price <br />levels and do not include any allowance for inflation, The total capital costs estimated for the <br />six project alternatives range from $1,9 million for Alternative 3 to $20,6 million for Alternative 6, <br /> <br />The annual project costs and the unit cost per acre-foot of additional water developed were <br />estimated for each project alternative under three different financial scenarios which were <br />selected to show the effects of various financing arrangements, The three financing scenarios <br />under which the project costs were evaluated are: <br /> <br />vi <br />
