Cardinal Lake Dam, located in Greenville, South Carolina, is a privately owned structure built in 1960 primarily for recreational purposes. The dam stands at a height of 22 feet and spans a length of 172 feet, with a storage capacity of 96 acre-feet. Situated on Buckhorn Creek, the dam is regulated by the South Carolina Department of Health and Environmental Control (DHEC) and undergoes regular inspections to ensure its safety and compliance with state regulations.

Despite being classified as a high hazard potential structure, Cardinal Lake Dam is assessed to be in fair condition as of the last inspection in October 2019. The dam's Emergency Action Plan (EAP) status and risk assessment details are currently pending updates. With its stone core and earth foundation, the dam serves as a recreational feature for the surrounding area, offering a surface area of 7 acres for various water activities. The dam's location in a picturesque setting makes it a popular destination for water resource and climate enthusiasts looking to enjoy the beauty of the outdoors.

As the Charleston District of the US Army Corps of Engineers does not have jurisdiction over Cardinal Lake Dam, its oversight and maintenance fall solely under the authority of private ownership. With its vital role in providing recreational opportunities and water storage capacity, the dam serves as a notable landmark in the region. Despite being a privately owned structure, Cardinal Lake Dam plays a significant role in water resource management and climate resilience efforts in the area.
