Released On: May 07, 2004
The May 2004 forecast indicates a full water supply for senior water right users and a 70 percent supply for junior water right users. The tight water supply will result in low carryover at the end of the 2004 season. Current system storage is 74 percent of capacity and 94 percent of average.
Specific water delivery levels will not be determined until later this month. In all conditions listed below, senior water rights holders would receive their full water supply. Estimated water supplies for junior (proratable) users, given a range of future precipitation, are as follows:
50% of normal future precipitation â€“ 65% supply for junior users
70% of normal future precipitation â€“ 70% supply for junior users
100% of normal future precipitation â€“ 76% supply for junior users
The Bureau of Reclamation will announce the adopted rationing level when it is actually implemented. 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.
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. If warm, dry weather persists conditions could worsen.
