Name O'Sullivan Dam
Details An irrigation dam at the southeast end of Potholes Reservoir is nine miles south of the community of Moses Lake, WA in southeast Grant County. The dam forms a retaining wall for water impounded in the Potholes Reservoir, in the middle of Columbia Basin Project. It is also called Potholes Dam and South Coulee Dam. It was named for James O'Sullivan of Ephrata and Spokane, through Public Law 814 which was passed by congress on June 29, 1948. O'Sullivan worked for many years on projects dealing with eastern Washington irrigation. He had been administrative assistant of Columbia Basin Commission, and was largely responsible for the construction of the dam which now bears his name.
