About Montgomery Lake
The primary purpose of Montgomery 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 Mays Montgomery (private). It impounds the Tr-swan Creek near Athens Se Suburb.
The dam stands 15 feet tall and stretches 480 feet across, has a maximum storage capacity of 87 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 1964, 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.
Living Downstream
If you live or work downstream of this dam, consider taking these steps: learn your local evacuation routes, check whether your county emergency management office has a dam failure inundation map, and sign up for local emergency alerts. Alabama is the only state with no dam safety program, so there is no state office to contact about this structure; the federal record above is what exists. ASDSO's page on Alabama explains the gap.
