TABLE 4 <br />RIDGWAY RESERVOIR ACCOUNT ALLOCATION <br />ALLOCATION <br />ACCOUNT (acre-feet) <br />1. Municipal and Industrial: <br /> City of Montrose 10,000 <br /> City of Delta 3,700 <br /> Town of Olathe 300 <br /> Menoken Water Co. 640 <br /> Chipeta Water Co. 600 <br /> TCWCD 12,860 <br /> Recreation Areas 100 <br />Sub-tota l 28,200 <br />2. Irrigation: <br /> UVWUA 10,300 <br /> Un-allocated 900 <br />Sub-tota l 11,200 <br />3. Total 39,400 <br />Hydrologic studies indicate that Ridgway Reservoir will fill in every year except extreme drought years, <br />even when project deliveries ultimately reach the full allocation levels shown in the Table 4. It is noted <br />that between the joint-use pool and the active conservation pool, there is approximately 59,400 acre-feet <br />of storage. According to TCWCD staff, in any year that the reservoir might not completely fill, the <br />municipal and 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 the end of the <br />water year (October 31), all water in any of the subaccounts reverts to a common pool, where it is <br />reallocated to the various accounts in the following year. It is therefore in the UVWUA's interest to fully <br />utilize their Ridgway irrigation allocation 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 prevent a <br />fishery loss over the spillway. The USBR provides estimates of the projected runoff above the reservoir, <br />and then the TCWCD makes releases through the outlet works to draw the reservoir down to storage <br />levels sufficient to accommodate the predicted runoff without a spill. Winter release rates for this <br />program will typically be less than 100 cfs during the mid-winter months and in the range of 450 to 575 <br />cfs during the early spring runoff months. Target storage levels are discussed later in the Key <br />Assumptions section. <br />General Description of Project 7 Water Authority <br />Project 7 was formed to provide domestic and municipal water treatment for its members, each of which <br />is responsible for providing its own raw water supply. Project 7 owns no water rights. The treatment <br />facility is the old City of Montrose plant near Fairview Reservoir, rehabilitated and enlarged to a design <br />capacity of 27 million gallons per day (MGD) for Project 7 purposes. Presently, the average peak daily <br />rate and the average daily rate are approximately 14 MGD and 11 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 acre-feet) was <br />delivered to the City of Montrose. Treated water deliveries have doubled in the last 4 years. <br />3 <br />A275 01.09.95 1.15-20 Fosha, Hyre <br />
