"Precipitation in the basin’s mountains has been above average the last three months and has more than made up the deficit we were facing at the end of January," said Chuck Garner, Yakima Project River Operations supervisor. "The reservoirs are in a good position to fill and the unregulated runoff should meet most of the water demands well into June."
Reclamation will issue water supply forecasts monthly through July. Specific water delivery levels will not be determined until later in the year after reservoir storage begins to decline.
The May TWSA forecast is based on flows, precipitation, snowpack, and reservoir storage as of May 1, along with estimates of future precipitation and river flows. Other future weather conditions that help determine the timing of the run-off and the demand for water are also critical in determining streamflows, prorationing, and reservoir storage.
"We are looking forward to a full water supply for all users," said Chuck Garner. "The snowmelt timing, the summer weather, and the irrigation demands are still important unknown factors that can influence stream flow levels and the carry-over storage at the end of the season." Garner recommends that irrigators always consider practices that conserve water.
