Nix Lake Dam

About Nix Lake Dam

The primary purpose of Nix Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Glen Hughes (private). It impounds the Wasson Branch.

The dam stands 23 feet tall and stretches 525 feet across, creates a reservoir covering 135 acres, has a maximum storage capacity of 1,398 acre-feet, and collects water from a drainage area of 3 square miles. Completed in 1940, the structure is well-established, with more than 75 years of service.

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 10/02/2023.
