Dam profile
NID height · 90 ft90 ft tall and 8,500 ft long, taller than 97% of U.S. dams with a recorded height. Height is drawn to scale against a ten-story building, about 100 ft; the profile is a generic embankment section and the water level is illustrative.
About Weiss - Highway 411 Dike
The primary purpose of Weiss - Highway 411 Dike is hydroelectric. The dam generates hydroelectric power by channeling water through turbines, converting the energy of flowing water into electricity. The dam is owned by Alabama Power Company (public utility). It impounds the Coosa near Centre.
The dam stands 90 feet tall and stretches 8,500 feet across, creates a reservoir covering 30,200 acres, has a maximum storage capacity of 306,400 acre-feet, and collects water from a drainage area of 5,273 square miles. Completed in 1961, 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 satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 10/26/2021.
At 90 feet, this dam is taller than 97% of all dams in the United States.
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.
