Mccolumn W Fallow Dam, located in Lexington, South Carolina, is a privately owned structure primarily utilized for recreation purposes. This earth dam, completed in 1900, stands at a height of 14 feet and spans a length of 420 feet, providing a storage capacity of 77 acre-feet. Despite its low hazard potential, the dam's condition assessment was deemed poor during its last inspection in April 2017.

The dam overlooks the TR-LIGHTWOOD KNOT CREEK and is regulated by the South Carolina Department of Health and Environmental Control (DHEC). While the dam's maintenance and enforcement fall under state jurisdiction, it lacks certain critical features such as an emergency action plan and updated inundation maps. Despite its age and condition, Mccolumn W Fallow Dam remains a valuable recreational asset, attracting water resource and climate enthusiasts to its pleasant surroundings.

With its historical significance dating back over a century, Mccolumn W Fallow Dam serves as a testament to the intersection of water management, leisure activities, and environmental stewardship. As stakeholders continue to monitor and assess the dam's condition, there is a shared commitment to preserving its integrity and ensuring its safety for future generations of visitors and enthusiasts.
