For Release: June 08, 2004

The Bureau of Reclamation has just released the June 2004 forecast for irrigation water supply according to David Murillo, Yakima Project Manager. The June rationing estimate improved compared to the May estimate due to a combination of factors. May runoff came in a very orderly fashion allowing much of the water to be used or stored. In addition, the irrigation districts managed demands tightly in May and this improved the supply.

The June 2004 forecast indicates a full water supply for senior water right users and an 82 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 88 percent of capacity and 98 percent of average.

Specific water delivery levels will not be determined until about mid-month. 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 - 69 percent supply for junior users Most likely - 82 percent supply for junior users High estimate - 100 percent 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.
