Swan Lake Wildlife Area

The Swan Lake Wildlife Area is a 2,466 acre tract of protected land located in Columbia County, Wisconsin, managed by the Wisconsin Department of Natural Resources (WDNR). Land to be used for the wildlife area was first acquired in 1963 to provide for hunting and other outdoor recreational activities in the county. In addition to outdoor recreation activities, the wildlife area was established to protect the Fox River watershed.
