Sangamon River Watershed (Ill.)
Geographic Coverage:Illinois
Abstract:The Sangamon River basin drains 5,419 square miles and forms the largest watershed of any of the tributaries of the Illinois River. The main stem of the Sangamon River flows more than 240 miles. This assessment report covers the upper Sangamon River watershed from the vicinity of Gibson City southwestward to near Illiopolis. More specifically, the Upper Sangamon River Area Assessment encompasses approximately 1,220.5 square miles (781,139.7 acres) in east-central Illinois, including significant portions of Piatt and Macon counties, the northwestern portion of Champaign County, and smaller parts of Christian, Dewitt, Ford, Logan, McLean, Sangamon, and Shelby counties. One of the thirteen sub-basins in this assessment area, the Sangamon River (upper central), encompassing 53,734 acres, was designated as a "Resource Rich Area" because it contains significant natural community diversity. The Upper Sangamon River Ecosystem Partnership was subsequently formed around this core area of high quality ecological resources. 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, focusing on Piatt and Macon counties; Part II, Environmental Quality, discusses air and water quality, and hazardous and toxic waste generation and management in the area; and Part III, Archaeological Resources, identifies and assesses the archaeological sites known in the area.
