With a low hazard potential and a moderate risk assessment rating, Greenville plays a crucial role in water resource management in the region.
The dam's primary purpose is hydroelectric power generation, and it has a spillway width of 400 feet for uncontrolled overflow. With a maximum discharge capacity of 66,935 cubic feet per second, Greenville serves as a key infrastructure for flood control and water supply management. The dam has not undergone any recent condition assessment, but it is inspected every three years to ensure its safety and functionality.
Despite its age, Greenville remains a vital component of the local water resource infrastructure, contributing to the region's energy production and water management efforts. As climate change impacts water resources and hydrology, the role of dams like Greenville in mitigating risks and ensuring reliable water supply becomes increasingly significant for the community and the environment.
