Crystal Lake Dam, located in Berkeley, South Carolina, was completed in 1973 and serves primarily for recreational purposes. This privately owned earth dam stands at a height of 22 feet and spans a length of 1140 feet, with a storage capacity of 1344 acre-feet. The dam overlooks the picturesque Mill Branch river, offering visitors a serene lake environment for various water activities.

Despite its scenic beauty, Crystal Lake Dam poses a significant hazard potential with a poor condition assessment as of December 2017. It is subject to state regulation and inspection by the South Carolina Department of Health and Environmental Control (DHEC). With a history of poor maintenance, there is a pressing need for risk management measures to be implemented to ensure the safety of the surrounding community in the event of an emergency.

As water resource and climate enthusiasts explore the ecological significance of Crystal Lake Dam, its maintenance and risk assessment remain vital considerations for the local authorities. Efforts to improve the dam's condition and emergency response plans are crucial in safeguarding the environment and ensuring the sustainable use of this recreational water resource.
