Anderson Lake State Fish and Wildlife Area

Illinois

The 2,247-acre Anderson Lake State Fish and Wildlife Area is in west-central Illinois, about 11 miles north of Browning in Fulton County along Route 100.

The wildlife area contains two lakes that attract myriad waterfowl. Anderson Lake is a floodplain lake that frequently receives overflow waters from the Illinois River. Carlson Lake, the smaller of the two, is drained in early summer, planted to feed ducks and then flooded in the fall to attract waterfowl. Bottomland woods including silver maple, cottonwood and willow trees, surrounds the lakes.

Combined, the lakes and woodlands offer roosting, feeding and resting areas for many species of waterfowl, especially Mallards and Wood Ducks, as well as Bald Eagles that spend the winters there. American White Pelicans rest and feed during spring migration.
