Oxbow Dam is a hydroelectric run-of-the-river rockfill dam in the western United States, on the Snake River in Hells Canyon (river mile 273) along the Idaho-Oregon border.
Description
Completed in 1961,[1] the dam is part of the Hells Canyon Project that also includes Hells Canyon Dam and Brownlee Dam, all built and operated by Idaho Power Company.
The dam's powerhouse contains four generating units with a total nameplate capacity of 190 megawatts (250,000 hp).
Lacking passage for migrating salmon, the three Hells Canyon Project dams blocked access by anadromous salmonids to a stretch of the Snake River drainage basin from Hells Canyon Dam up to Shoshone Falls, which naturally prevents any upstream fish passage to the upper Snake River basin.
Heliport
Oxbow Heliport is a private 100 by 100-foot (30 by 30-metre), turf heliport owned by Idaho Power.[2]
