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). 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.
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.
