Built in 1958, this Earth-type dam stands at 30 feet high and spans a length of 950 feet, creating a reservoir with a storage capacity of 5,200 acre-feet. With a surface area of 142 acres and a maximum discharge capacity of 1,275 cubic feet per second, the dam holds a significant amount of water from Mill Creek, providing both recreational opportunities and essential water resources for the area.
Managed by the Mississippi Department of Environmental Quality, Lake Copiah Dam has been deemed to have a high hazard potential but is currently in fair condition. Inspected every five years, the dam's emergency action plan was last revised in 2007. With a moderate risk assessment rating of 3, the dam's risk management measures and inundation maps are yet to be prepared. Despite these factors, the dam continues to play a vital role in water resource management and climate resilience efforts in Copiah County, Mississippi.
