Many wildlife species use the Refuge. As many as 20 bald eagles and over 200,000 waterfowl may concentrate on the Refuge during fall migration. Well over 200 bird species have been observed on the Refuge since 1975. A bird checklist is available on this Web site, or through the Refuge Manager.
Mammals common to the Refuge include: raccoon, striped skunk, black-tailed prairie dog, eastern cottontail, and mule and white-tail deer.
Some of the fish species found in Refuge lakes include walleye, crappie, yellow perch, wiper, northern pike, white bass, catfish, and carp.
The Refuge is used primarily as a resting and feeding area for waterfowl and shorebirds and, to a lesser extent, for waterfowl production. The Refuge also provides habitat for migrating and nesting bald eagles and offers a recreational program compatible with the management of Refuge wildlife.
