About Lake Lockloma Dam
The primary purpose of Lake Lockloma Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Lockloma Rec Area (private). It impounds the Tr-black River near Poplar Bluff.
The dam stands 15 feet tall, creates a reservoir covering 26 acres, has a maximum storage capacity of 209 acre-feet, and collects water from a drainage area of 160 square miles. Completed in 1956, 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.
