Senior water rights holders will receive their full water supply. The adopted prorationing level for junior users is listed below:
Adopted prorationing level: 38 percent of full supply.
Precipitation is only one factor affecting the water supply. Other future weather conditions that determine the timing of the natural run-off and that effect demand for water are critical in determining the effect on reservoir storage, the amount of water available for irrigation, and the rationing level. Because of these unknown future conditions and uncertainty in the basin conditions, the Yakima Field Office provides a likely range for the total water supply available estimate and the associated rationing level. In June, a reasonable range for the rationing level is between 32 percent and 48 percent of full supply with the adopted rationing level at 38 percent of full supply for junior, pro-rated, entitlements. The total water supply available will be adjusted bi-weekly or as needed to reflect changing conditions. Post-1905 water rights have been curtailed since April 6th.
The water supply can be improved through prudent use of water, said Murillo.
The Yakima Basin Storage System began drafting and went on storage control on May 25, approximately one month earlier than average. Total storage reached 869,986 acre-ft, which is 82 percent of full capacity.
