Potholes Reservoir Supplemental Feed Route
Environmental Assessment

The Bureau of Reclamation has issued a final Environmental Assessment and Finding of No Significant Impact for the Potholes Reservoir Supplemental Feed Route which will increase the reliability of transporting water from Banks Lake to Potholes Reservoir located about 22 miles south of Ephrata, Washington.

Potholes Reservoir is a key feature of the Columbia Basin Project and serves as a vital source of irrigation water. Potholes Reservoir has traditionally been fed water through the East Low Canal, but due to operational changes over the years, it was necessary to find reliable alternatives to supply a portion of the feed to Potholes Reservoir.

Request a printed copy of the document by calling (509) 754-0200 or pick one up at 32 C Street NW, Ephrata, WA.
