2026 October Water Supply Update

9.25.2026 October Water Supply Update

The Bureau of Reclamation provided an update today on October water supplies for senior and junior water users, forecasting a 100% supply for both.

Throughout September, Reclamation continued operating the Yakima Project in a manner that raised significant concern that available water could be exhausted before September 30, potentially placing senior water users at risk of a second consecutive curtailment. Despite those concerns, cooler temperatures and wetter weather during September provided much-needed relief and improved water conditions. As a result, SVID now expects to receive the water necessary to continue October deliveries.

Based on the improved water supply outlook, Sunnyside Valley Irrigation District (SVID) plans to continue water deliveries through October 19, 2026.

SVID plans to begin shutting down the Sunnyside Canal on October 19, with the shutdown expected to be completed by October 21, 2026. Some laterals and deliveries may continue to have water available for a few days afterward as the canal system drains and is dewatered.

Laterals 27.69 and 52.90 will be shut off on October 14, 2026, to allow construction to begin on this year’s ELIPS piping projects.

Growers should plan their remaining irrigation needs accordingly.

ABOUT SVID

Sunnyside Valley Irrigation District is a leading irrigation district serving over 94,000 acres in the Yakima Valley. The district is the second largest of six divisions of the U.S. Bureau of Reclamation’s Yakima Project. Sunnyside Valley Irrigation District comprises approximately 95 percent of the land in the Sunnyside Division and is responsible for operating and maintaining the conveyance and distribution facilities in the area. The district’s water supply comes from the Yakima River Watershed, which includes five storage reservoirs with a total storage capacity of 1-million-acre feet.

Since its establishment in 1905, Sunnyside Valley Irrigation District has been a critical part of the Yakima River Basin’s development. The district’s history dates back to the late 1800s when the Konewock Ditch Company and Piety Flat Ditch Company began diverting water to their respective lands. With its rich history and expertise in irrigation, Sunnyside Valley Irrigation District is committed to providing its customers with reliable and efficient irrigation services year after year.
