<br />Water Year 1990 <br /> <br />Navajo Reservoir is projected to be drawn down to about <br />elevation 6051 feet by February 1990, Under a most probable <br />runoff water year, releases are projected to remain near 600 <br />cfs over the entire water year, resulting in Navajo Reservoir <br />filling to about elevation 6068 feet, or 85 percent full, by July <br />1990. <br /> <br />With a reasonable maximum runoff water year, Navajo <br />Reservoir is expected to fill to the normal water surface <br />elevation of 6085 feet, with maximum releases of about 3,000 <br />cfs during the months of May through June, A reasonable <br />minimum level of runoff would not change the release pattern <br />from the 600 cfs level provided for irrigation, consumptive use, <br />and maintenance of fish and wildlife, <br /> <br />NAVAJO STORAGE <br /> <br />1000 ACRE-FEET <br />'.00 <br /> <br /> <br />1<00 <br /> <br />1200 <br /> <br />1000 <br /> <br />.00 <br /> <br />000 <br /> <br />000 <br /> <br />.00 <br /> <br />00 N 0 J F M A M J J A 8 0 N D J F W A M J J A S 0 <br />ACTUAL 1989 AND PROJECTED 1990 <br /> <br />PROJECTED OPERATION 1990 <br />REASONABLE MAXIMUM RELEASES <br /> <br />_Of. <br />o <br /> <br />o <br /> <br /> <br />. <br /> <br />D <br /> <br />MOST PROBABLE RELEASES <br /> <br />o <br /> <br />. <br /> <br />. <br /> <br />D <br /> <br /> <br />REASONABLE MINIMUM RELEASES <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br /> <br />NDJFMAMJJASO <br /> <br />12 <br />
