O'Sullivan Dam, one of the larger earthfill dams in the United States (200 ft/61 m high; 19,000 ft/5,791 m long; completed 1949), is on Crab Creek in Washington state about 45 km south of Ephrata and 25 km south of Moses Lake. The 27,800-acre (113 km2) Potholes Reservoir formed by this dam collects return flows from all irrigation in the upper portion of the project for reuse in the southern portion. A system of wasteways has been built on both the West and East Low Canals to provide operational safety for the canals and a means of delivering water into Potholes Reservoir to supplement the natural and return flows.

The dam was built as part of the Columbia Basin Project.
