About Twitty Dam

The primary purpose of Twitty Dam is water supply. The dam stores water for municipal, industrial, or agricultural use, helping ensure a reliable supply for the surrounding area. The dam is owned by City Of Monroe (local government). It impounds the Stewarts Creek near Olive Branch.

The dam stands 60 feet tall and stretches 790 feet across, creates a reservoir covering 327 acres, has a maximum storage capacity of 17,000 acre-feet, and collects water from a drainage area of 35 square miles. Completed in 1973, 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 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 08/08/2024.

At 60 feet, this dam is taller than 95% of all dams in the United States.
