About Mallard Lake Dam
The primary purpose of Mallard Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Frsn.-mllrd. Home Owners (private). It impounds the Bee Branch near Cottondale.
The dam stands 26 feet tall and stretches 270 feet across, and has a maximum storage capacity of 159 acre-feet. Completed in 1948, the structure is well-established, with more than 75 years of service.
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.
