WATER SUPPLY <br />The DWCD holds storage water rights for the Beaver Creek Reservoir <br />for over 16,000 acre-feet. <br />The average annual runoff was estimated using Bureau of Reclamation <br />runoff correlations for the years 1952 through 1971 which estimated <br />the average runoff to be 350 acre-feet per square mile for the <br />average basin elevation of 9000 feet. The total average annual <br />runoff for the basin would be 8750 acre-feet per year. Assuming a <br />dry year yield of 25~ of the average year, would result in 2200 <br />acre-feet. <br />The annual water supply should be adequate to fill a 1500 acre-foot <br />reservoir each year. <br />The alternative Bear Creek Reservoir has a significantly larger <br />drainage area and a higher average elevation which would yield <br />considerably more water to fill the proposed 1500 acre-foot <br />reservoir. The DWCD also has water rights for this site. <br />RESERVOIR <br />Table 1 shows the elevation-area-capacity values for the Beaver <br />Creek Reservoir. Table 2 shows the same data for the Bear Creek <br />Reservoir. The areas and associated capacities were developed from <br />1 inch equals 2000 feet USGS Quad maps. <br />In order to store 1500 acre-feet the Beaver Creek reservoir water <br />level would be at elevation 8284 feet, 39 feet above the stream <br />channel. The Bear Creek reservoir water level would be at <br />elevation 8046 feet, 92 feet above the stream channel. About 40 <br />acre-feet of inactive storage is included in each reservoir. The <br />water level for the Beaver Creek Dam is 53 feet less than Bear <br />Creek Dam. <br />Beaver Creek Dam 5 <br />
