Yakima Basin Water Supply - July Forecast Released
YAKIMA, Wash. - The Bureau of Reclamation's July 2013, Total Water Supply Available (TWSA) forecast for the Yakima Basin indicates a full water supply for both senior and junior water rights.

"Even though the weather in June helped preserve water in the reservoirs, the natural runoff was below average and is forecasted to be below average for the rest of the summer," said Chuck Garner, Yakima Project River Operations supervisor.

The July TWSA forecast is based on flows, precipitation, snowpack, and reservoir storage, along with estimates of future precipitation and river flows. Other future weather conditions that determine the timing of the run-off and the demand for water will also influence streamflows, reservoir storage, and the actual water supply available.

"With the summer irrigation season in full swing, the reservoir system is being used to meet demands. We expect low reservoir storage at the end of the irrigation season, possibly the lowest we've seen since 2006. Water saved through good irrigation practices could help preserve a little more water in the reservoirs," Garner said.
