About Lake Manr Dam

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

The dam stands 38 feet tall and stretches 720 feet across, creates a reservoir covering 39 acres, has a maximum storage capacity of 1,053 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1949, 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. Its condition is rated fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 06/16/2022.

At 38 feet, this dam is taller than 85% of dams nationwide.
