Upper Rock River Watershed (Ill.)
Geographic Coverage:Illinois
Abstract:The Upper Rock River Assessment Area is defined by that portion of the Rock River watershed downstream from the Illinois-Wisconsin state line to the Rock River's confluence with Pine Creek near Grand Detour. The area falls predominantly within Winnebago and Ogle counties, with small areas in four additional counties -Boone, Carroll, Lee, and Stephenson. Encompassing approximately 830 square miles, the Upper Rock River area is located almost entirely within the physiographic division defined as the Rock River Hill Country. This division has been glaciated, but the glacial deposition is relatively thin, particularly for the western portion of the area. The topography is characterized by rolling hills and well-developed stream valleys. 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 III, Archaeological Resources, identifies and assesses the archaeological sites known in the area.
