About Lake Greenbrook Dam

The primary purpose of Lake Greenbrook Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Lake Greenbrook Poa (private). It impounds the Rockey Creek near Southaven.

The dam stands 25 feet tall and stretches 880 feet across, creates a reservoir covering 73 acres, has a maximum storage capacity of 1,300 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1969, the structure is well into its service life at over 50 years 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. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam.
