Sam Rayburn Dam: FAQ
- Where is Sam Rayburn Dam?
- In Jasper County, Texas (TX). 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 Sam Rayburn Dam?

- Who owns Sam Rayburn Dam?
- EIA-860M names USACE-Fort Worth District 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 Sam Rayburn Dam LLC?
- Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — USACE-Fort Worth District 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 "Sam Rayburn Dam LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
