Completed in 1973, this gravity dam serves the purpose of hydroelectric power generation and stands at a height of 64 feet with a length of 300 feet. The spillway, with a controlled design and a width of 60 feet, is equipped with two Tainter (radial) outlet gates, allowing for a maximum discharge of 43,222.1 cubic feet per second.
With a storage capacity of 1,160,298 acre-feet and a surface area of 7,565 acres, Jocassee Spillway plays a crucial role in managing the Keowee River's flow. The dam's hazard potential is classified as high, and the risk assessment rates it as very high (1), underscoring the importance of its management and maintenance. Despite its structural significance and operational capacity, the condition assessment of Jocassee Spillway is currently not available, highlighting the need for ongoing monitoring and evaluation to ensure its continued safety and reliability for water resource and climate enthusiasts.
As a prominent feature in the Nashville District, Jocassee Spillway is a testament to engineering excellence and environmental stewardship. Its association with two other structures underscores its interconnectedness within the region's water infrastructure. With Congressman Jeff Duncan (R) as the local representative, the spillway's role in supporting energy production, water management, and flood control in Oconee County, South Carolina, showcases its multifaceted contributions to the community and the surrounding ecosystem.
