Gantts Pond Dam, also known as Roy Williams Dam, is a privately owned structure located in Lexington, South Carolina. Built in 1955, this Earth dam stands at 17 feet tall and spans a length of 380 feet, creating a reservoir with a storage capacity of 92 acre-feet. Its primary purpose is for recreation, offering a surface area of 10 acres for visitors to enjoy water activities.

Managed by the South Carolina Department of Health and Environmental Control, Gantts Pond Dam is state-regulated and has undergone inspections to ensure its safety. Despite its low hazard potential, the dam's condition assessment in 2017 rated it as poor, highlighting the need for maintenance and potential improvements. With a moderate risk assessment level, there are ongoing discussions on implementing risk management measures to address any potential issues and ensure the safety of the surrounding community.

The dam's location on the TR-MCCARTHA BRANCH river stream and its association with Congressman Joe Wilson reflect its importance within the local ecosystem and community. As water resource and climate enthusiasts, understanding the significance of structures like Gantts Pond Dam is crucial in preserving our natural resources and ensuring sustainable management practices for the future.
