In gaining environmental <br />approvals for the construction of Stagecoach, the UYWCD committed to maintaining <br />downstream flow of 40 cfs or the reservoir inflow, whichever is less, from December 1 <br />through July 31; and a minimum release of 20 cfs from August 1 through November 30. <br />According to the UYWCD, the hydro equipment is not sized to feasibly operate at flow <br />rates less than 40 cfs. Therefore, it has been the practice of the UYWCD to operate at a <br />minimum flow rate of 40 cfs. The maximum flow rate that can be accommodated by the <br />turbines is approximately 115 cfs. Bypassed inflows and/or releases in excess of 115 cfs <br />are routed through the larger outlet of the dam, bypassing the hydro plant. <br />2.11. Allen Basin Reservoir <br />Allen Basin Reservoir (WDID 583500) is a small irrigation reservoir located near the <br />headwaters of Middle Hunt Creek. It plays a significant role in the irrigation water supply <br />in this water limited area of the Yampa River basin. The reservoir has a decreed capacity <br />of 2,250 acre-feet which is also reported to be its active capacity, there being no dead <br />storage. The storage right was adjudicated in 03-30-1964 and carries an appropriation <br />date of 10-20-1953. The Division 6 engineer provided a regression equation relating the <br />reservoir water surface area to the capacity. This equation is recommended for purposes <br />of estimating evaporation losses from the reservoir: <br />Yampa River Basin Information 2-15 <br />
