White Oak Mtn. Dam #4, located in Polk, North Carolina, is a privately owned earth dam built on Horse Creek for recreational purposes. Standing at a structural height of 20 feet with a hydraulic height of 15.2 feet, this dam has a storage capacity of 22 acre-feet and covers a surface area of 1.7 acres. With a drainage area of 102 square miles, the dam has the potential to discharge up to 159 cubic feet per second.

Despite its high hazard potential, White Oak Mtn. Dam #4 has been assessed as satisfactory in its condition, with the last inspection conducted in March 2020. The dam is regulated and permitted by the North Carolina Department of Environmental Quality's Dam Safety Program, ensuring that state inspections, enforcement, and permitting are in place to maintain its safety and structural integrity. The dam's Emergency Action Plan (EAP) status and risk management measures are yet to be fully established, highlighting the need for preparedness in case of emergencies related to the dam's operations.

Water resource and climate enthusiasts interested in the management and safety of dams, particularly in the context of recreational activities, can find White Oak Mtn. Dam #4 an intriguing case study. The dam's location in Columbus, North Carolina, its association with Horse Creek, and its high hazard potential add layers of complexity to understanding the balance between recreational benefits and the need for stringent regulatory oversight to mitigate risks associated with dam failure. As the dam continues to be monitored and inspected regularly, it serves as a reminder of the importance of proactive maintenance and emergency preparedness in safeguarding water resources and surrounding communities.
