Des Plaines River Valley The Des Plaines River Valley is a river corridor in northeastern Illinois that traverses suburban and industrial regions of Cook County, Illinois, Lake County, Illinois, Will County, Illinois, and DuPage County, Illinois. The valley links a chain of wetlands, bluffs, and floodplains between the upper Great Lakes Basin and the Chicago River watershed, forming a linear landscape that has shaped transport, settlement, and conservation in the Chicago metropolitan area and Northeastern Illinois Planning Commission jurisdictions.
Geography
The valley runs roughly southwest from the vicinity of Lake Zurich, Illinois and Wauconda, Illinois through corridors adjacent to Mettawa, Illinois, Des Plaines, Illinois, O'Hare International Airport, and Joliet, Illinois before approaching the confluence near Lockport, Illinois and the Illinois and Michigan Canal National Heritage Area. Topographically the corridor contains glacial landforms associated with the Wisconsin glaciation, including moraines, outwash plains, and kettle lakes such as Busse Lake and Lake Catherine (Cook County). Adjacent municipal jurisdictions include Schaumburg, Illinois, Elk Grove Village, Lemont, Illinois, and Forest Preserve District of DuPage County holdings. Transportation corridors that parallel the valley include segments of Interstate 294, Interstate 55, Interstate 90, the Metra commuter rail network, and historic rights-of-way such as the Illinois and Michigan Canal and the Michigan Central Railroad alignment.
Hydrology and Water Quality
Hydrologically the river is part of the larger Great Lakes Basin and interacts with engineered features of the Chicago Area Waterway System and the Chicago Sanitary and Ship Canal. Surface flow varies seasonally with snowmelt influenced by Lake Michigan levels, controlled releases from upstream retention basins, and inputs from tributaries such as the Salt Creek (Des Plaines River tributary), Monee Creek, and the Little Calumet River system. Water-quality issues have been addressed through collaborative programs led by agencies including the United States Environmental Protection Agency, the Illinois Environmental Protection Agency, and local entities like the Forest Preserve District of Cook County. Historical pollution concerns have involved combined sewer overflows affecting parameters regulated under the Clean Water Act, while contemporary monitoring targets nutrients, turbidity, and contaminants associated with industrial legacy sites listed by the United States Environmental Protection Agency Superfund program.
History and Cultural Significance
Indigenous habitation by peoples associated with the Potawatomi, Miami (tribe), and Ojibwe trading networks shaped early human use of the valley. European exploration and settlement during the 17th and 18th centuries connected the corridor to the French colonial empire in North America and voyageurs tied to the Chicago Portage. The valley figured in 19th-century infrastructure projects such as the Illinois and Michigan Canal, the Illinois Central Railroad, and later the Pere Marquette Railway expansions, which influenced the growth of towns like Joliet, Illinois and Des Plaines, Illinois. Social movements and institutions including the Civilian Conservation Corps and the National Park Service have influenced preservation efforts, while cultural sites within the corridor reflect links to industrial histories recorded by the Historic American Engineering Record.
Ecology and Wildlife
The valley supports habitats ranging from floodplain forest and cattail marsh to oak savanna and prairie remnants, hosting species documented by conservation partners such as the Illinois Department of Natural Resources and non-governmental organizations like The Nature Conservancy. Avifauna include migrants noted on inventories aligned with the Audubon Society and breeding populations of waterfowl, herons, and raptors such as the Bald eagle since reintroduction and recovery efforts. Aquatic communities include native and non-native fishes influenced by connectivity with the Chicago Sanitary and Ship Canal and invasive species pathways identified by the United States Fish and Wildlife Service. Vegetation communities contain species of conservation interest monitored under regional plans administered by the Chicago Wilderness consortium.
Recreation and Parks
Public recreation is provided through preserves and facilities managed by entities like the Forest Preserve District of Cook County, the Forest Preserve District of DuPage County, and municipal park districts including Joliet Park District and Des Plaines Park District. Trail systems such as segments of the Grand Illinois Trail, the Prairie Path (Illinois), and local multiuse paths link sites including Springbrook Prairie Forest Preserve, Buffalo Creek Forest Preserve, and boat launches near Romeoville, Illinois. Recreational programming includes birdwatching coordinated with the Audubon Society of Illinois, paddling managed by regional outfitters, and historical interpretation connected to the Illinois and Michigan Canal National Heritage Corridor.
Flood Control and Management
Flood risk reduction combines engineered structures and landscape-scale approaches. Major projects have involved the Lockport Powerhouse and Dam, stormwater detention basins overseen by the Metropolitan Water Reclamation District of Greater Chicago, and regional planning through the Illinois Department of Natural Resources office of water resources. Post-disaster recovery has engaged federal programs administered by the Federal Emergency Management Agency and state hazard mitigation funded through the Illinois Emergency Management Agency. Watershed-scale initiatives emphasize riparian restoration and green infrastructure promoted by organizations including the Natural Resources Conservation Service and local conservation districts.
Infrastructure and Development
Infrastructure in the valley includes freight and passenger rail corridors operated by companies such as Union Pacific Railroad and BNSF Railway, airport-related development around O'Hare International Airport, and industrial complexes in municipalities like Steger, Illinois and Homer Glen, Illinois. Land-use decisions involve regional planning bodies including the Chicago Metropolitan Agency for Planning and local zoning authorities. Redevelopment projects have sought to balance economic activity, transport logistics tied to the Port of Chicago (Chicago), and conservation goals advanced by partnerships among the Openlands organization and municipal governments.
