Des Plaines Fish and Wildlife Area is an Illinois state park on 5000acre in Will County, Illinois, United States. It is located on floodplain adjacent to the confluence of the Des Plaines River (after which this park was named) and the Kankakee River to form the Illinois River.HistoryPrior to 1948 what is now called the Des Plaines Fish and Wildlife Area was owned by the federal government. The Illinois Department of Conservation acquired the site in 1948 and established its use as a recreation area. Additional land was accessed following the completion of Interstate 55 in the 1960s. From that time to 1975, the area was used primarily by hunters and unmanaged day use. The Division of Land Management took over the area in 1976 and since then, extensive upgrading of facilities has occurred. In recent years, more than 350,000 people annually visit Des Plaines—an area of over 5,000 acres, with approximately 200 acres of water.PicnickingA restful break from hunting, fishing or hiking can be a special event. Picnickers can choose to lunch along the Kankakee River or under the large shelter on the banks of Milliken Lake. Both sites provide tables, stoves and water along with cooling shade trees and picturesque views. A playground area is also provided at the Milliken Lake site.FishingOpen water and ice fishing are popular events as well, and productive! Milliken Lake, as well as several ponds and the river backwaters, provide panfish, catfish, and bass fishing. Milliken Lake is stocked with catchable trout in the spring. The Kankakee River borders the site on the south with 3 miles of shoreline providing access to boating enthusiasts and excellent walleye and northern pike fishing.
