The 2023 Irrigation Season Begins…
The South Columbia Basin Irrigation District will begin filling the Potholes Canal on March 1, 2023. Deliveries from the Potholes Canal will begin on March 15, 2023, to the Mattawa area, the Potholes Canal service area of Franklin County, and Blocks 2 and 3. Deliveries to Block 18 and other lands served from the East Low Canal system will begin as water becomes available from East Columbia Basin Irrigation District.
Irrigation deliveries will be dependent on demand in the individual lateral systems. In locations where pumping plants are required for irrigation deliveries, startup dates will depend on adequate orders to start the pumping plants.
Landowners will need to contact their Watermaster office for specific delivery dates and water availability.
