Glenn Forest Dam, located in Spartanburg, South Carolina, was completed in 1990 and stands at a height of 24 feet. The dam is primarily used for recreational purposes, offering a serene escape for water resource and climate enthusiasts. With a normal storage capacity of 48 acre-feet and a maximum storage of 98 acre-feet, the dam creates a surface area of 5 acres along TR-FOURMILE BRANCH.

Managed by a private owner, Glenn Forest Dam is regulated, permitted, inspected, and enforced by the South Carolina Department of Health and Environmental Control (DHEC). Despite its high hazard potential, the dam is currently assessed to be in fair condition as of the last inspection in January 2021. The dam's emergency action plan (EAP) status and risk assessment measures remain unspecified, highlighting the importance of continued monitoring and maintenance to ensure the safety and sustainability of this vital water resource infrastructure.
