Big Stone National Wildlife Refuge was originally purchased by the U.S. Army Corps of Engineers and was transferred to the U.S. Fish and Wildlife Service on May 21, 1975. The refuge currently includes 11,586 acres in Big Stone and Lac qui Parle Counties, in Minnesota.
Big Stone Wetland Management District covers two counties in southwest Minnesota, Lincoln and Lyon counties. Our staff manages all federal lands, easements and private land projects in both of these two counties.
