An Endangered Species in Illinois
River otters are an endangered species in Illinois and were reintroduced to Evergreen Lake and the Mackinaw River Valley with a release of 30 otters 1996. The transplanted otters come from Louisiana, where thriving populations of river otters exist.
Range of a River Otter
The river otter may range over a 60-mile radius, moving between several food source locations to keep all viable. A summer sighting at Evergreen Lake included baby otters in 1997. Anyone seeing an otter in Illinois is asked to report the location to the Illinois Department of Natural Resources.
