==Description== thumb|left|Oxbow Dam power station Completed {{Time ago|1961}} in 1961,<ref name=oxbcom/> 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 {{convert|190|MW}}.
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.
