Trout Pond — formerly called Old Pond — located near Wardensville in Hardy County, West Virginia, USA, is the state's only natural lake. The small "lake" is situated in the Trout Pond Recreation Area (TPRA) of the George Washington National Forest. Formerly, the pond had fluctuated in surface area between 2 and 3 acres, but recently it has appeared to be disappearing due to underground structural changes.
