to approximately 645 feet at the end of May and
maintained between that level and 635 feet
through September, The highest water level was
646 teet, with an act'lve storage of 1,792,000 acre-
feet on May 29, 1976, which is about the beginning
of the heavy irrigation season, The water level
was drawn down during the summer months to
