Flow Restrictions Change with updated Reclamation forecast

The U.S. Bureau of Reclamation (BOR) has released the April prorationing percentage. Thanks in part to above average precipitation in March, water supply has increased from 48 percent to 58 percent. SVID continues to closely monitor Yakima Basin drought conditions, and as restrictions change, updates will be posted online. March flow restrictions of 5.0 gallons per minute per acre have been lifted with new restrictions set at 6.7 gallons per minute per acre. The next BOR drought forecast will be released mid April.

2025 Canal Priming Schedule begins on March 17, 2025

Sunnyside Valley Irrigation District will open the head gate on the Sunnyside Division Dam on Monday March 17, 2025, to begin canal priming. Due to the time, it takes for the water delivery system to fill, many water users closer to the main canals may have access earlier depending upon their location along the canal system. Priming the entire system will take priority over water deliveries. This means the water surface elevation in the Sunnyside Canal may not be high enough to make deliveries until the system is primed. The canal priming will continue throughout the next two weeks. SVID anticipates that irrigation water will be available to all water users by request by April 1, 2025. Tentative Priming Schedule: Head Gate Monday March 17, 2025 Lower Division Wednesday March 19, 2025 Snipes Lateral, Mabton Monday March 24, 2025 30.20, 23.10, 39.79 and 48.04 Tuesday March 25, 2025 Prosser, 49.71 and others as needed Wednesday March 26, 2025 All dates are subject to change due to weather and unanticipated circumstances.
