Box Canyon Dam: FAQ
- Where is Box Canyon Dam?
- In Siskiyou County, California (CA). The map on this page is placed at the coordinates EIA files for the plant, which locate the site rather than any individual unit.
- How big is Box Canyon Dam?
- 5 MW of nameplate capacity across 2 units, as of the EIA-860M release for 2026-07.
- Who owns Box Canyon Dam?
- EIA-860M names Siskiyou Power Authority as the reporting entity. That is the operator of record on the survey, which is not always the ultimate owner.
- Is this the same as Box Canyon Dam LLC?
- Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Siskiyou Power Authority here — not the project company that holds the asset. Project companies are commonly registered as an LLC carrying the plant's name, so a search for "Box Canyon Dam LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
