Most of this 2,900 acre site is open water, a back water slough of the Illinois River, making it an ideal resting place for migrating waterfowl. Managed for duck hunting, many of the 3 miles of trails are closed during hunting season. There are picnic and camping facilities. The bottomland forest on the point of land that juts out to the north of the campground is a prime stop over for the spring migration of warblers. Great Blue Herons, Great White Egrets and Green Herons may be seen wading in the shallows. Songbirds and woodpeckers are common, as are Barred Owls, Red-tailed Hawks and Goshawks.
Waterfowl hunting is permitted on two backwater lakes of the Illinois River: Goose Lake; and the upper part of Upper Peoria Lake. Total area: 2,900 acres — 1,200 acres for waterfowl hunting; 1,200 acres set aside as waterfowl refuge.
