Oxbow Dam is a hydroelectric run-of-the-river rockfill dam on the Snake River on the Idaho-Oregon border, in Hells Canyon (river mile 273). Completed 59 years ago in 1961,[1] it is part of the Hells Canyon Project that also includes Hells Canyon Dam and Brownlee Dam, 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.
