About University of Montevallo Lake Dam
The primary purpose of University of Montevallo Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by U.of Montevallo (private). It impounds the Tr.shoal Creek near Montevallo.
The dam stands 22 feet tall and stretches 350 feet across, and has a maximum storage capacity of 86 acre-feet. Completed in 1958, 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. Notably, no emergency action plan is currently on file for this high-hazard dam.
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.
