Information: Crab Orchard Lake was created when Crab Orchard Creek, a tributary of the Big Muddy River in southern Illinois, was dammed in the 1930s for purposes of recreation and flood control. The Crab Orchard National Wildlife Refuge was established August 5, 1947 following the transfer of all land previously held by the Crab Orchard Creek Project and the Illinois Ordnance Plant to the United States Fish and Wildlife Service.
