Comanche Trail Lake Dam

About Comanche Trail Lake Dam

The primary purpose of Comanche Trail Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by City Of Big Spring (local government). It impounds the Big Spring Draw near Big Spring.

The dam stands 24 feet tall and stretches 1,105 feet across, creates a reservoir covering 22 acres, has a maximum storage capacity of 520 acre-feet, and collects water from a drainage area of 7 square miles. Completed in 1914, 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. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. An emergency action plan is in place for this dam. The most recent inspection on record was 10/24/2018. That was 7 years ago, which is on the longer end for a high-hazard structure.

If you live or work downstream of this dam, consider taking these steps: learn your local evacuation routes, check whether your county emergency management office has a dam failure inundation map, and sign up for local emergency alerts. The Texas dam safety program can provide more specific information about emergency planning for this structure.
