<br />r-CJ 1 b ., [) <br />],I .:> <br /> <br />. <br /> <br />. <br /> <br />works tunnel site is completed. Bids were opened on January 19 for con- <br /> <br />struction of the 8-mile-long Silt Pump Canal which will convey irrigation <br /> <br />water to lands on the lower portion of ffarvey Mesa. Award of contract is <br /> <br />pending. <br /> <br />CRSP Reservoirs <br /> <br />Glen Canyon powerplant is now operating with three generating units <br /> <br />and all are operating at near capacity. Fourth unit should be placed in <br /> <br />operation within the next week. Runoff has been high since late December <br /> <br />because of high te~eratures and precipitation and releases from Navajo <br /> <br />and Flaming Gorge. Some water was bypassed at Glen Canyon in late <br /> <br />December. <br /> <br />Our January 1 mean forecast of April-July r\.ID.off at Lees Ferry is <br />9,000,000 acre--reet or slightly higher than the 1923-1964 mean for the <br /> <br />same period. This figure e,sStnnes average precipitation throughout the <br /> <br />remainder of the year, however. January precipitation was nearly normal. <br /> <br />Based on the January 1 forecast of 9,000,000 acre-feet, the mean forecast <br /> <br />of April-July runoff at Navajo Dam is 900,000 acre-feet, and at FlamiIlg <br /> <br />Gorge it is 1,100,000 acre-feet. <br /> <br />In view of the forecast, we have increased releases from Navajo Reser- <br /> <br />voir to minimize the possibility of interference of the rising reservoir <br /> <br />with construction of the Navajo Indian Irrigation Project canal headworks. <br /> <br />We now estimate that the reservoir will be drawn down to a minimtnn storage <br />1> <br />of about 230,000 acre-feet in March end/then rise to about 455,000 acre- <br /> <br />feet by July. On February 1, storage was about 330,000 acre-feet. <br /> <br />3 <br />
