Mann Creek Dam
Mann Creek Dam (National ID # ID00285) is a dam in Washington County, Idaho, in the western part of the state, a few miles north-northeast of the town of Weiser.
The earthen dam was an irrigation project of the United States Bureau of Reclamation. Completed in 1967, the dam impounds Mann Creek with a height of 148 feet above bedrock, and a length of 1176 feet along its crest.[1] The dam is operated by the local Mann Creek Irrigation District.
Mann Creek Reservoir has a surface area of 283 acres (115 ha). At closure it had a maximum capacity of 13,000 acre-feet but siltation reduced that number to 10,900 acre-feet by 1992.[2] The western side of the lake is the location of the former Mann Creek State Park. Boating and fishing are the main recreational activities.[3]
