The March 2005 forecast predicts a very short water supply for junior users even if precipitation for the remainder of the season is average. "Even if future conditions are favorable, the water supply is not adequate this year," Murillo said. This is due to an unusually small snow pack and less precipitation than average for the water year to date.
Specific water delivery levels will not be determined until later in the year. In all conditions listed below, senior water rights holders would receive their full water supply. Estimated water supplies for junior (proratable) users are as follows:
Low Estimate 14 percent supply for junior users Most Likely Estimate 34 percent supply for junior users High Estimate 58 percent supply for junior users
Irrigation districts and water users are urged to apply their own judgment in deciding which level of supply may be realized. Water demands requiring storage releases, even prior to storage control, may be charged to the users' total entitlement. The water supply can be improved through prudent use of water. Please conserve water.
Future precipitation is only one factor affecting the water supply. The weather conditions that determine the timing of the run-off and demand for water are critical in determining whether the reservoirs fill, the amount of water available for irrigation, and rationing levels.
