<br />G01l2d3 <br /> <br />The cost of construction is estimated to be $935,000,000.00 in 1980 <br />dollars (not including the annual cost of power to pump the water) and the <br />development period, including time for site specific environmental <br />analyses, permitting and construction is estimated to be 25 years. <br /> <br />In addition, the annual power cost required to pump the water into the <br />Denver System is estimated at $22,000,000.00 per year in 1980 dollars, <br />which has been capitalized to represent $348,000,000.00 of capital value. <br /> <br />Williams Fork Collection System <br /> <br />The Williams Fork Collection System includes the completion of the <br />gravity collection system extending south and west from the west portal of <br />the Gumlick Tunnel (middle and south sector) and the extension of the <br />system from the Tunnel north (north sector). The Collection system will <br />deliver water by gravity to the Gumlick Tunnel and thence through the <br />Vasquez Tunnel to the Moffat Tunnel for delivery into the Gross Reservoir. <br /> <br />The water rights for the Williams Fork Collection system are adjudi- <br />cated. <br /> <br />With these systems operated as though senior to Denver's Williams Fork <br />Reservoir, the increase in firm annual yiel~ to the Denver system from the <br />operation of the completed system is estimated to be 12,000 acre feet per <br />year (5,000 from the north sector and 7,000 from the middle and south <br />sector) . <br /> <br />The cost of construction is estimated to be $42,000,000.00 in 1980 <br />dollars, and the development period, including time for permitting and <br />construction is estimated to be 9 years. <br /> <br />Two Forks Reservoir <br /> <br />Two Forks Reservoir, located just below the confluence of the North <br />Fork of the South Platte River with the South Platte River will regulate <br />flows of both of those rivers as well as deliveries through the Harold D. <br />,Roberts Tunnel. <br /> <br />Water rights for the Reservoir have been adjudicated. <br /> <br />The staff evaluation has studied approximately fifty (50) alternate <br />sites for the proposed Two Forks site. Functionally viable alternatives, <br />however, exist only in a handful of those sites or combinations of sites, . <br /> <br />-7- <br />
