Olhl(;~8 environmental analyses, permitting and construction in segments is esti- mated to be 20 to 25 years. Eaq1e Colorado Collection System 1. As an extension of the Eagle-Piney Gravity System. As an extension of the Eag1e-Piney Gravity System, the Eag1e C010rada C011ection System would divert water by gravity from the Eagle River near Avon or pump water from the Eagle River near Wolcott as we11 as from the Colorado River near State Bridge and store it In the Eagle Colorado reservoir on A1ka11 Creek, from which it would be pumped into the Eag1e- Piney Gravity System and be carried by gravity through the Vail Pass Tunnel to Di110n Reservoir. The water rights for this un1t are in the process of being adjudi- cated; the Referee has rejected the Board's c1aim and the matter is now pending before the Water Judge on Denver's protest to the Referee's ruling. The increase in firm annual yield to the Denver System from the operation of this unit is estimated to be 106,000 acre feet per year. The cost of construction is estimated to be $626,000,000.00 in 1980 dollars (not including the cap1ta1ized cost of annual power deliveries required to pump the water) and the development period, Including time for site specific environmental ana1yses, permitting and construction is esti- mated to be 25 years. In addition, the annualized power cost is estimated to be $14,000,000.00, which is capitalized at a value of $224,000,000.00 in 1980 dol1ars. 2. Without use of the Eag1e-Piney Gravity System. The Eag1e Colorado System developed without use of the Eagle-Piney Gravity System, wi1l divert water by gravity from the Eag1e River near Avon or pump water from that river near Wo1cott as we11 as from the Colorado River near State Bridge and store it in the Eagle C01orado Reservoir on Alkali Creek from which It will be pumped through a series of pipe1ines and tunnels to the Vail Pass Tunnel for delivery into Dillon Reservoir. The increase in firm annual yield to the Denver system from the operation of this unit is estimated to be 170,000 acre feet per year. -6-
