The Washo Reserve is a 1040 acre natural area in South Carolina owned by the Nature Conservancy, a national conservation organization. The Reserve features a 200 year old freshwater cypress lake and cypress-gum swamp, which harbors the oldest wading bird rookery in continuous use in North America. Over 50 pairs of osprey nest here making the Washo one of the largest concentrations of this bird of prey along the entire East Coast.
