Final Environmental Assessment for the US Highway 10 and US Highway 45 Interchange on a portion of the Rat River Wildlife Area, Winnebago County, Wisconsin


The final Environmental Assessment (EA) and Finding of No Significant Impact (FONSI) is available for public information on the  US Highway 10 and US Highway 45 Interchange in Winnebago County, Wisconsin.  The FONSI was signed on October 26, 2001.  The interchange will result in approximately 32 acres of the Wisconsin DNR held Rat River WA impacted by the action. The Rat River Wildlife Area was purchased in part with Wildlife and Sport Fish Restoration funds "to provide wildlife based recreation including hunting, trapping and compatible non-hunting recreation as well as for the production of waterfowl." Of the 32 acres, approximately 19 acres of wetland and 13 acres of upland habitat will be impacted. Wisconsin DOT has purchased approximately 55 acres adjacent to the RRWA to compensate for the 32 acre loss. This property consists of 35 acres of wetland and 20 acres of upland habitat.
