Broadmouth Creek WCD Dam-Minor 4, located in Anderson, South Carolina, is a vital piece of infrastructure designed by USDA NRCS in 1966 to primarily reduce flood risk in the area. This earth dam stands at a height of 37 feet and spans 420 feet, providing a storage capacity of 376 acre-feet to control water levels in the TR-Broad Mouth Creek. Despite its fair condition assessment in 2017, this dam has a low hazard potential and is regularly inspected every five years to ensure its safety and functionality.

Managed by the local government, Broadmouth Creek WCD Dam-Minor 4 is regulated by the South Carolina Department of Health and Environmental Control (SC DHEC) and is subject to state permitting, inspection, and enforcement. The dam's spillway, which is controlled, helps manage water flow during high levels, while the uncontrolled outlet gates provide additional control mechanisms. With a normal storage capacity of 56 acre-feet and a surface area of 13 acres, this dam plays a crucial role in protecting the surrounding area from potential flooding events, making it a key asset for water resource and climate enthusiasts to monitor and appreciate.
