Show Colorado runoff forecast cut Shrinking snow pack in high mountain during March along with precipitation recorded at only 30 of normal for the month of March has slashed Upper Colorado River Basin runoff forecast to 4,500,000 acre-feet for April through July. Unseasonably high March temperautres accelerated runoff run-off from mountain snow banks so that measured runoff on principal streams has been well above normal. For first six months of water year (October 1965 through March 1966) the total runoff has been 3,900,000 acre-feet or 1,300,000 acre-feet above average. Therefore, despite des-pite low April 1 forecast of 4,500,000 acre-feet , for April through July runoff, the total runoff for the water year would total about 9,300,000 acre-feet, or 75 of the longtime long-time average. With the prospect of 9,300, 000 acre-feet for total water year runoff, Lake Mead would be held at or above rated head elevation for the Hoover Dam power plant. Also, Lake Powell Pow-ell would rise some before receding to a level well above minimum power pool. Thus, continued power production at Glen Canyon is assured. Flaming Flam-ing Gorge would rise then fall a little below its present level by April of next year. |
