Big Muddy River Watershed (Ill.)
The Big Muddy River Assessment Area is defined by the watershed of the Big Muddy River, excluding the watersheds of two tributaries, Beaucoup Creek and Kinkaid Creek, which are covered in the Kinkaid Area Assessment. The Big Muddy area covers approximately 1,731 square miles, falling within portions of 10 counties: Franklin, Hamilton, Jackson, Jefferson, Johnson, Marion, Perry, Union, Washington, and Williamson. The area is located within two physiographic divisions, the Mt. Vernon Hill County, which is characterized by mature topography of low relief, with a complete drainage system, and the Shawnee Hills Section, which is characterized by dissected uplands, narrow valleys, steep slopes, and greater relief.
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, Socia-Economic Profile, discusses the demographics, infrastructure, and economy of the area; Part IT, 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.
