Donnells Dam, Hydroelectric power station in Tuolumne County, California, US.
The concrete arch dam spans 293 meters across the Middle Fork of the Stanislaus River, creating Donnell Lake within Stanislaus National Forest.
The Tri-Dam Project, which includes Donnells Dam, began construction in 1955 after extensive negotiations between irrigation districts to meet water demands.
The dam represents California's commitment to renewable energy development during the 1950s, combining power generation with agricultural irrigation needs.
Visitors can access multiple recreational activities including fishing, boating, and hiking around the dam, which generates 72 megawatts of hydroelectric power.
The dam's design allows it to impound 70,176,000 cubic meters of water while supporting irrigation for 117,500 acres of farmland across two counties.
