O'Sullivan Dam (National ID # WA00268), one of the largest 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 the U.S. state of Washington, 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.
