Ardoch National Wildlife Refuge was established in 1939, and originally consisted of 2,696 acres of flowage and refuge easements and 288 acres of fee title land around Lake Ardoch, a reservoir. Since then, 80 acres of easement land have been deleted and an additional 20 acres of fee title land has been added.
