Cornwell Dam, located in Lancaster, South Carolina, is a privately owned structure built in 1972 primarily for recreational purposes along the TR-SIXMILE CREEK. With a height of 20 feet and a length of 320 feet, the dam has a storage capacity of 51 acre-feet and a surface area of 6 acres. Despite being classified as having a low hazard potential, the dam's condition assessment in 2017 was marked as poor, highlighting the need for maintenance and upgrades to ensure its safety and longevity.

The dam's regulatory oversight falls under the jurisdiction of the South Carolina Department of Health and Environmental Control (DHEC), with state permitting, inspection, and enforcement all in place. The structure's risk assessment is moderate, with a rating of 3 on the scale, indicating a need for risk management measures to address any potential safety concerns. The last inspection in 2017 revealed issues with the dam's condition, emphasizing the importance of regular assessments and maintenance to mitigate risks and ensure the safety of the surrounding community and environment.

As a key feature in the area's water resource and climate landscape, Cornwell Dam provides not only recreational opportunities but also serves as a reminder of the importance of proper dam management and maintenance. With its location in a scenic natural setting and the potential risks associated with its condition, the dam stands as a symbol of the delicate balance between human development and environmental stewardship in the face of changing climate conditions.
