Dry Falls Dam is a rockfaced earthfill-type[3] dam in the U.S. state of Washington. Located in Grant County near Coulee City, it was built as part of the Bureau of Reclamation's Columbia Basin Project. Water from the Columbia River, impounded by Grand Coulee Dam, is pumped into Grand Coulee, a formerly dry canyon, via the short Feeder Canal. Grand Coulee's north end is sealed by North Dam and Dry Falls Dam stretches across the mid-section of the Coulee. This allows the water pumped from the Columbia River to fill the upper Grand Coulee, creating a large equalizing reservoir known as Banks Lake. Water from the reservoir is fed into the irrigation project's Main Canal, which runs south from Dry Falls Dam to another reservoir called Billy Clapp Lake, formed by Pinto Dam.
