The Columbia Intake Control Structure is a vital infrastructure in South Carolina, serving as a public utility for hydroelectric power generation and water supply. Built in 1882, this stone dam stands at a height of 8 feet and spans a length of 209.5 feet, with a storage capacity of 800 acre-feet. Situated on the Broad River in Richland County, the structure is owned and regulated by the Federal Energy Regulatory Commission, ensuring its safe operation and maintenance.

Despite its age, the Columbia Intake Control Structure remains a key component in managing water resources in the region, with a significant hazard potential due to its high risk assessment rating. While the condition assessment is currently not available, regular inspections are conducted to ensure the structure's integrity. Emergency action plans are in place, meeting guidelines for emergency preparedness and response, with updated contacts and risk management measures to mitigate potential risks associated with the dam.

With no state jurisdiction or regulatory agency oversight, the Columbia Intake Control Structure falls under federal authority, emphasizing the importance of federal regulations and inspections in safeguarding the structure and surrounding communities. As a critical piece of infrastructure for both hydroelectric power generation and water supply, this historic dam plays a crucial role in managing water resources and supporting the region's sustainable development in Columbia and beyond.
