About Johnson Farm Lake Dam
The primary purpose of Johnson Farm Lake Dam is fire protection, stock, or small fish pond. The dam maintains a small impoundment used for fire suppression, livestock watering, or as a fish pond. The dam is owned by Billy Johnson (private). It impounds the Tr-hallmark Creek Trib 4 near Locust Fork.
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.
