<br />UPPER BASIN RESERVOIRS <br /> <br />FONTENELLE RESERVOIR <br />(GREEN RIVER) <br /> <br />Water Year 1993 <br /> <br />Fontenelle Reservoir began water year 1993 with an <br />elevation of 1975.9 meters (6483.0 feet) with 226 million <br />cubic meters (183,000 acre-feet) of live storage (53 percent <br />of capacity). This low level of storage was the result of the <br />extremely dry conditions experienced in the Upper Green <br />River Basin in water year 1992 Inflow into FonteneUe was <br />only 47 percent of normal in water year 1992. <br /> <br />Precipitation and snowpack in water year 1993 was <br />moderately above normal. Because of the dry antecedent <br />soil and groundwater conditions in the Upper Green River <br />Basin, however. runoff was moderately below normal. April <br />through July runoff into Fontenelle Reservoir during water <br />year 1993 was 934 million cubic meters (757,000 acre-feet). <br /> <br />ACT\IAL RELEASES 1l1t13 <br /> <br />IIWOII culle ....- <br />- <br /> <br />-............ <br />314 <br /> <br /> 2 <br /> I 1\ <br /> / ./ ~1 <br /> '" <br /> ........ . <br />I--' <br /> <br />:tOO <br /> <br />a <br /> <br />200 <br /> <br />12 <br /> <br />, <br /> <br />,.. <br /> <br />:,. ; ~ ., ~ .; .; ; ., .,..". ~o <br /> <br /> <br />This was 89 percent of the long-term average. The Upper <br />Green River Basin was the only drainage basin in the Upper <br />Colorado River Basin where runoff was below normal in <br />1993. <br /> <br />With near average inflows, Fontenelle easily filled in 1993. <br />Releases of up to 119 cubic meters per second (4,200 cubic <br />feet per second) were released in 1993. Peak inflow into <br />Fontenelle Reservoir was 222 cubic meters per second (7,840 <br />cubic feet per second) on June 4, 1993. Approximately 321 <br />million cubic meters (260,000 acre-feet) of water bypassed <br />the turbines in water year 1993. <br /> <br />FONn!NI!LLE RESERVOIR <br /> <br />Reservoir <br /> <br />Slorage Capacity <br />Normal Pool Elevation <br />Minimum Power Pool <br />Surface A1<a, full <br />Reservoir Length, full <br /> <br />426 minion cubic meters (345,000 acre-reet) <br />1982.9 mele..
