Ridgway Reservoir Account Allocation <br />Allocation <br />Account (acre-feet) <br />1.

Total 39,400 <br />Hydrologic studies indicate that Ridgway Reservoir will fill in every year except extreme <br />drought years, even when project deliveries ultimately reach the full allocation levels <br />shown in the previous table. It is noted that between the j oint-use pool and the active <br />conservation pool, there is approximately 59,400 acre-feet of storage. According to <br />TCWCD staff, in any year that the reservoir might not completely fill, the municipal and <br />industrial and irrigation pools are essentially assured a complete fill, even if it comes at <br />the expense of a complete fill of the 20,000 acre-foot conservation pool in that year. At <br />the end of the water year (October 31), all water in any of the subaccounts reverts to a <br />common pool, where it is reallocated to the various accounts in the following year. It is <br />therefore in the UVWUA's interest to fully utilize their Ridgway irrigation allocation <br />every year, since it does not carry over. <br />TCWCD and the USBR have coordinated a "no spill" policy for the reservoir in order to <br />prevent a fishery loss over the spillway. The USBR provides estimates of the projected <br />runoff above the reservoir, and then the TCWCD makes releases through the outlet works <br />to draw the reservoir down to storage levels sufficient to accommodate the predicted <br />runoff without a spill. Winter release rates for this program will typically be less than <br />100 cfs during the mid-winter months and in the range of 450 to 575 cfs during the early <br />spring runoff months. Target storage levels are discussed later in the Key Assumptions <br />section. <br />2.3.2. General Description of Project 7 Water Authority <br />Project 7 was formed to provide domestic and municipal water treatment for its members, <br />each of which is responsible for providing its own raw water supply. Project 7 owns no <br />water rights. The treatment facility is the old City of Montrose plant near Fairview <br />Reservoir, rehabilitated and enlarged to a design capacity of 27 million gallons per day <br />(MGD) for Project 7 purposes. Presently, the average peak daily rate and the average <br />daily rate are approximately 14 MGD and ll MGD, respectively. During the recent <br />water year 1994, Project 7 treated a total of 7,940 acre-feet, 42 percent of which (3,350 <br />Gunnison River Basin Information 2-7 <br />
