<br />Water Year 1987 <br /> <br />It is projected that Navajo Reservoir will be drawn down to <br />near elevation 6,042 feet by April 1987 in preparation for dam <br />safety modification work. A hydrofraise concrete cutoff wall <br />is scheduled to be constructed to reduce the amount of <br />seepage through the embankment dam. Releases are <br />expected to be held near 2,000 cfs throughout most of the 1987 <br />winter months to accomplish this level of drawdown. An above <br />average runoff during water year 1987 is expected to fill <br />Navajo Reservoir and a reasonable minimum level of inflow <br />would cause the minimum releases to be near the 800 cfs level <br />for irrigation, consumptive use, and maintenance of fish and <br />wildlife. A reasonable maximum inflow would force releases <br />to about 3,800 cfs. <br /> <br />NAVAJO STORAGE <br /> <br />1000 ACRE-FEET <br />2000 <br /> <br />1000 <br /> <br /> <br />1200 <br /> <br />BOD <br /> <br /><DO <br /> <br />o <br />o N D J F MAW J J A 8 Q N D J F M A M J J A . <br />ACTUAl 1988 AND PROJECTED 1987 <br /> <br />PROJECTED OPERATION 1987 <br />REASONABLE MAXIMUM RELEASES <br /> <br />""'" en <br />. <br /> <br />. <br /> <br />1111......'11 <br />- 111I '11 <br />---......... ~.. <br /> <br />. <br /> <br />. <br /> <br />MOST PROBABLE RELEASES <br /> <br />. <br /> <br />B <br /> <br />. <br /> <br /> <br />o <br /> <br />REASONAIIl..E MINIMUM RB..EASES <br /> <br />< <br /> <br />. <br /> <br /> <br />. <br /> <br />NDJFMAMJJASO <br /> <br />12 <br />
