Thorn Creek Watershed (Ill.)
Geographic Coverage:Illinois
Abstract:The Thorn Creek Assessment Area is an approximately 104.26-mile2 (66,725 acre) area that includes portions of southern Cook County and northeastern Will County. This assessment area consists of the entire Thorn Creek basin in Illinois and includes the Butterfield Creek, Thorn Creek, Deer Creek, and North Creek sub-basins. These subbasins are in the Great Lakes drainage but are bordered to the south, west, and partially the north by the Mississippi River drainage; thus, the assessment area occurs adjacent to the divide between the two major drainage areas. The Thorn Creek sub-basin, encompassing 20,614 acres, was designated as a "Resource Rich Area" because it contains significant natural community diversity. The Thorn Creek Ecosystem Partnership was subsequently formed around this core area of high quality ecological resources. This assessment is comprised of four volumes. In Volume I, 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 and economy of the area; Part II, Environmental Quality, discusses air and water quality, and hazardous and toxic waste generation and management; and Part III, Archaeological Resources, identifies and assesses the archaeological sites known in the area.
