Natural resources conservation areas --Illinois --Calumet
The Calumet area encompasses approximately 184.3 square miles (117,961 acres) in southern Cook County and in a very small fraction of Will County. Waterways in the area include the Calumet-Sag Channel, Little Calumet River, Calumet River, Midlothian Creek, Tinley Creek, Lake Calumet, and WolfLake. The watershed is part of the Greater Chicago Metropolitan Region and has been extensively developed for urban and industrial use. Nonetheless, significant natural community diversity remains in the area in the form of pockets of environmentally important high quality habitats. It is around this core area of high quality ecological resources that the Lake Calumet Ecosystem Partnership was formed.
This assessment is comprised of four volumes. In Volume 1, Geology discusses the geology, soils, and minerals in the assessment area. Volume 2, Water Resources, discusses the surface and groundwater resources and Volume 3, Living Resources, describes the natural vegetation communities and the fauna of the region. Volume 4 contains three parts: Part I, Socio-Economic Profile, discusses the demographics, infrastructure, and economy of the area; Part II, Environmental Quality, discusses air and water quality, and hazardous and toxic waste generation and management in the area; and Part Ill, Archaeological Resources, identifies and assesses the archaeological sites known in the area.
