For Release: March 07, 2008
The Bureau of Reclamation has released the March 2008 forecast for irrigation supply in the Yakima Basin. The forecast is based on flow data, snowpack and precipitation data.
"We are expecting a normal to slightly above normal water supply at this time," said Chuck Garner, Yakima Project River Operations supervisor. "The March 2008 forecast indicates a full water supply for all water users."
As of March 1, system storage was 44 percent full and 79 percent of average.
"We are very encouraged by the snowpack but reservoir storage is low for this time of year. We will depend on that snow to help fill reservoirs and meet the stream flow and irrigation demands in the basin," Garner said.
At this time both junior and senior water right holders are expected to receive their full water supply. Specific water delivery levels will not be determined until later in the year.
The weather conditions that determine precipitation, run-off timing and demand for water are critical in determining whether reservoirs fill, the amount of water available for irrigation and possible rationing levels. If warm weather prompts an early snowmelt run-off, and dry conditions prevail, the situation could worsen.
Water demands requiring storage releases, even prior to storage control, may be charged to the users' total entitlement.
