Lake Diana Dam

About Lake Diana Dam

The primary purpose of Lake Diana Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Grady F Abercrombie Jr;j D Crenshaw Cemetery (private). It impounds the Tr-cedar Creek.

The dam stands 22 feet tall, creates a reservoir covering 8 acres, and has a maximum storage capacity of 82 acre-feet. Completed in 1944, 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 06/14/2023.
