Abiquiu Dam: FAQ
- Where is Abiquiu Dam?

- Who owns Abiquiu Dam?
- EIA-860M names Los Alamos County - (NM) as the reporting entity. That is the operator of record on the survey, which is not always the ultimate owner.

- Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Los Alamos County - (NM) 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 "Abiquiu Dam LLC" usually means this site.
