Canal Priming Schedule 2024

Sunnyside Valley Irrigation District will open the head gate on the Sunnyside Division Dam on Monday March 18, 2024, 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, 2024.

We will also be treating with Cascade and/or Teton (Endothall). If you do not wish to use treated water for any reason, you are advised to discontinue using the irrigation water, beginning on the day of treatment and for at least two days thereafter.
