1) Firm annual yield is defined as the quantity of water that can be supplied every year without
shortage during the study period of 1951 through 1983. A projected high future-level of
water development was applied without and with pumpback to Dillon Reservoir from Green
Mountain Reservoir.

Wolford Mountain A' would receive inflow only from Muddy Creek, or alternatively,
supplement Muddy Creek storage with water diverted and pumped from the Colorado River.

Essentially all inflow to Wolcott would be pumped. For the 350,000 af High Wolcott, water
would be diverted and pumped from both the Eagle and the Coiorado Rivers. For the
160,000 af Low Wolcott, water would be diverted and pumped from the Eagle River only.
