Located along the historic Kankakee River, the park is dynamically affected by seasonal flooding. This, along with different natural communities, provides ideal feeding in the fields for a variety of wildlife. Densely wooded areas and the remnants of old river channels provide excellent habitat for a large deer herd, many species of ducks, and other wildlife. Preservation of these natural habitats is one of the primary goals of the Lake County Parks and Recreation Department.
