Blue Lake Dam, located in Dillon Sc, North Carolina, was completed in 1931 for the primary purpose of recreation. The dam, which sits on Gum Swamp Creek, is a private structure with a low hazard potential and fair condition assessment. Standing at a structural height of 15 feet and a hydraulic height of 8 feet, the earth-filled dam spans 250 feet in length and has a maximum storage capacity of 50 acre-feet.

Despite not being state-regulated, Blue Lake Dam undergoes regular inspections, with the last assessment conducted in February 2013. The dam's normal storage capacity is 42 acre-feet, covering a surface area of 25 acres. With a maximum discharge rate of 66 cubic feet per second, the dam serves as a vital recreational spot for the local community, offering opportunities for boating, fishing, and other water activities. While it may not be a massive structure, Blue Lake Dam plays a crucial role in providing water resources and leisure opportunities for residents in Scotland County, North Carolina.
