Weiss - Main Dam, also known as Powerhouse Dam and West Freeboard Dike, is a significant earth and gravity dam located in Cherokee, Alabama.
Completed in 1961, this dam serves primarily for hydroelectric purposes and recreation, with a maximum storage capacity of 306,400 acre-feet. The dam boasts a structural height of 85.5 feet and a hydraulic height of 49 feet, making it a crucial infrastructure for the region.
Operated by a public utility, the Weiss - Main Dam is regulated by the Federal Energy Regulatory Commission (FERC) and has a high hazard potential due to its size and location on the Coosa River. The dam features a controlled spillway with a width of 16 feet and one Tainter (radial) outlet gate. Despite its age, the dam's condition assessment is not available, and it is considered to have a very high risk level, highlighting the importance of ongoing monitoring and maintenance to ensure safety and functionality.
With its significant role in providing hydroelectric power and recreational opportunities, the Weiss - Main Dam stands as a vital structure in the water resource management of the area. Its location, design, and historical significance make it a subject of interest for water resource and climate enthusiasts, showcasing the intersection of human engineering with natural landscapes in the region.
