Building Strong® at Detroit Dam and Reservoir

Detroit DamDetroit Dam is located at river mile 49 on the North Santiam River, about 45 miles southeast of Salem, Ore.

 

Detroit Dam is a concrete dam with gated spillways. It was completed in 1953 with Big Cliff Dam, located just downstream, at a cost of $62.7 million. Detroit Dam has two hydropower generating units which were put into service in 1953, capable of producing 50 megawatts each.

 

Detroit Dam works together with Big Cliff Dam to provide flood risk management. Detroit’s other authorized primary purposes also include hydropower, water quality improvement, irrigation, fish and wildlife habitat and recreation.

The reservoir is a designated stop along the Mt. Jefferson section of the Oregon Cascades Birding Trail.  This Trail is a self-guided auto tour of nearly 200 prime birding destinations in the Oregon Cascades. This area provides songbird habitat in its hardwood stands, while osprey use lakeshore snags and trees as roosts and nesting sites and waterfowl including common mergansers nest at the lake.

The Detroit project encompasses more than 6,500 acres. The reservoir is primarily managed through an agreement with the Willamette National Forest.

To mitigate impacts from Corps dams to Chinook salmon and winter steelhead within the North Santiam River Basin, the Corps constructed the Marion Forks Fish Hatchery and the Minto Collection Facility. These are operated by the Oregon Department of Fish and Wildlife with funds provided by the Corps. Additionally, the Corps supports ongoing efforts for the recovery of the Oregon chub within the North Santiam River basin.
