About Ratcliff Lake
The primary purpose of Ratcliff Lake is fish and wildlife pond. The dam creates habitat for fish and wildlife, supporting local ecosystems and potentially serving conservation goals. The dam is owned by Usda Fs (federal). It impounds the Trib To Cochino Bayou.
The dam stands 24 feet tall and stretches 1,150 feet across, has a maximum storage capacity of 500 acre-feet, and collects water from a drainage area of 19 square miles. Completed in 1936, 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. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 09/09/2009. That was 16 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
