Buford Dam, also known as Lake Sidney Lanier, is a crucial federal structure located on the Chattahoochee River in Georgia's Gwinnett County. Completed in 1958 by the US Army Corps of Engineers, this earth dam serves primarily for flood risk reduction but also supports hydroelectric power generation and recreational activities. With a height of 231 feet and a storage capacity of 2.55 million acre-feet, Buford Dam plays a vital role in water resource management and protection in the Atlanta metropolitan area.

Despite being classified as having a high hazard potential, Buford Dam is well-designed, well-constructed, and well-maintained. The risk assessment conducted by the US Army Corps of Engineers in 2020 identified moderate risks associated with the dam, highlighting potential scenarios of catastrophic flooding downstream in case of a dam failure. To manage these risks, the Corps continuously collaborates with local emergency managers, updates emergency action plans, conducts regular inspections, and engages in maintenance and repair activities when needed.

As a water resource and climate enthusiast, staying informed about the risk management measures for Buford Dam is crucial. Engaging with local representatives, purchasing flood insurance, creating a family emergency plan, and being aware of evacuation routes are essential steps to ensure preparedness and safety in the event of a major flood. By following updates from the Mobile District and Lake Lanier on social media and taking proactive measures, individuals can contribute to the resilience of the community and the protection of water resources in the region.
