At the close of the irrigation season last year, <br /> <br />Region 4 reservoirs were storing more water for future use than ever <br /> <br />before. <br /> <br />This is the time of the year when the magnitude of the runoff from <br /> <br />the Colorado River becomes pretty well known. Hence a somewhat complete <br /> <br />report is given. <br /> <br />Runoff from snowmelt this year is below normal. The April-July run- <br /> <br />off forecast of the Colorado River at Lee Ferry has declined from a <br /> <br />March 1 estimate of 7.0 million acre-feet to our present estimate of <br /> <br />about 4 1/2 million acre-feet. This is about 53 percent of normal for <br />this four-month period. In spite of the low snowmelt runoff, we are <br />anticipating a total of 9.4 million acre-feet or 76 percent of normal <br />for the water year which ends September 30, 1966. Above average flows <br /> <br />last fall and winter were largely responsible for the better showing <br /> <br />for the entire year. <br /> <br />Releases from Lake Powell are expected to total 7,9 million acre- <br /> <br />feet during this water year which is slightly greater than the demands <br /> <br />on Hoover for the same period, As a result, Lake Mead may rise slightly <br /> <br />during the water year. Releases from Lake Powell during the last few <br /> <br />months have been carefully controlled to practically eliminate fluctua- <br /> <br />tion in the water level at Lake Mead. This permitted ideal spawning and <br /> <br />habitat for newly hatched bass during this period. This turned out to <br /> <br />4 <br />
