About Lake Mineral Wells Dam

The primary purpose of Lake Mineral Wells Dam is water supply. The dam stores water for municipal, industrial, or agricultural use, helping ensure a reliable supply for the surrounding area. The dam is owned by City Of Mineral Wells (local government). It impounds the Rock Creek near Bennett (lakota).

The dam stands 54 feet tall and stretches 1,610 feet across, creates a reservoir covering 668 acres, has a maximum storage capacity of 16,356 acre-feet, and collects water from a drainage area of 63 square miles. Completed in 1920, the structure is over a century old.

This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life.
