<br />Water Year 1992 <br /> <br />Since the mean annual inflow of 1.2 million acre-feet far <br />exceeds the storage capacityof345.000acre-feet, there is little <br />chance that the reservoir will not fill during water year 1992. <br />In order to minimize the high releases that occur in the spring <br />and to ensure that the reservoir fills, it will be drawn down to <br />an appropriate level this winter, probably 10 minimum pool <br />e1e....tion (&<<;3 Ccet) ..t>ich corresponds to a volume oC93,OOO <br />acre-feel. <br /> <br />Releases should average about 1,200 cubic feet pet second <br />(cCs) through thc Call and winter months. Relcases at this level <br />wiU provide an appropriate level ofdrawdovm. for next season, <br />the water quality of the river for downstream municipal and <br />industrial uses. Under aU but the most adverse inflow <br />assumption, the reservoir is expected to fill in the summer of <br />1992. <br /> <br />ACTUAL STORAGE 1991 <br /> <br />THOUS.lrt.ND ACRE-FEET <br /><00 <br /> <br />200 <br /> <br /> I I <br />......, "- 1/ <br /> "" , , , 1 <br /> / <br /> "-, <br /> ..... <br /> <br />aoo <br /> <br />100 <br /> <br />o <br />o N 0 J <br /> <br />FMAMJ <br /> <br />J A S <br /> <br />PROJECTED RELEASES 1992 <br /> <br />THOUSAND ACRE-FEET <br />'00 <br /> <br />PAC' IN <br /> <br />...
