Green Peter Dam, Hydroelectric power station in Linn County, Oregon, US
The Green Peter Dam spans 1,500 feet across the Middle Santiam River, creating a reservoir with a surface area of 3,720 acres.
The United States Army Corps of Engineers completed this concrete gravity dam in 1967 to generate electricity and prevent flooding along the Middle Santiam River.
The facility incorporates two power-generating turbines that supply 80 megawatts of renewable electricity to communities throughout the Willamette Valley region.
Visitors access the reservoir through Whitcomb Creek Park, which provides 77 camping sites, boat ramps, and facilities for up to 100 people.
The dam maintains a dual-purpose system with Foster Dam located 7 miles downstream, regulating water release for optimal power generation and flood control.
