Riddle Lake Dam, located in Greenville, South Carolina, serves multiple purposes including fire protection, stock, and as a small fish pond. Built in 1964 by the USDA NRCS, this earth dam stands at a height of 27 feet and spans 300 feet in length. With a storage capacity of 67 acre-feet, the dam plays a crucial role in managing water resources in the area.

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. While classified as having a low hazard potential, the dam is considered to have a moderate risk level according to a risk assessment conducted in the past. Despite its uncontrolled spillway and outlet gates, the dam has not been rated for its condition assessment as of the last inspection in 2017.

For water resource and climate enthusiasts, Riddle Lake Dam presents an interesting case study in dam management and maintenance. Its location in the Charleston District and its association with the Natural Resources Conservation Service highlight the importance of collaboration between federal and state agencies in overseeing critical infrastructure. As climate change continues to impact water resources, the role of dams like Riddle Lake Dam in providing essential services and protecting communities becomes increasingly vital.
