Great Dismal Swamp National Wildlife Refuge is located in southeastern Virginia and northeastern North Carolina. Creation of the refuge began in 1973 when the Union Camp Corporation donated 49,100 acres of land to The Nature Conservancy. The refuge consists of almost 107,000 acres of forested wetlands that have been greatly altered by drainage and repeated logging operations. Lake Drummond, a 3,100 acre natural lake, is located in the heart of the swamp.
