Owned and operated by the US Army Corps of Engineers, this earth dam stands at 80 feet high and has a hydraulic height of 97 feet, with a structural height of 103 feet. Completed in 1954, the dam serves multiple purposes including flood risk reduction and recreation, offering a storage capacity of 2,722,100 acre-feet and a normal storage of 85,700 acre-feet.
To manage the risks associated with the dam, the USACE implements various measures such as regular inspections, repairs to the spillway channel, and monitoring the dam's soil pressure using relief wells and pumps. The agency collaborates closely with other organizations like the National Weather Service, U.S. Geologic Survey, and Mississippi Emergency Management Agency to ensure effective emergency response plans are in place. During high water events, dam safety professionals increase surveillance to 24 hours a day to optimize the dam's operations and respond promptly to any potential issues. Overall, Grenada Dam is a critical structure that plays a key role in minimizing flood risks in the region while balancing its various project functions.
