Abstract:The Lower Rock River Area Assessment continues the assessment ofthe Rock River basin that was begun with the Rock River Area Assessment in 1996. The area encompasses approximately 2,500 square miles in northwestern Illinois; including parts of Bureau, Carroll, Henry, Lee, Ogle, Rock Island, and Whiteside counties plus very small parts ofDe Kalb and Mercer counties. The area encompasses 29 subbasins along the Rock and Green Rivers, of which two have been designated a "Resource Rich Area" because they contain significant natural community diversity. The Lower Rock River Ecosystem Partnership was subsequently formed around this core area of high quality ecological resources. This assessment is comprised offive 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 ofthe region. Volume 4 contains three parts: Part I, Socio-Economic Profile, discusses the demographics, infrastructure, and economy ofthe area, focusing on the five counties with the greatest amount ofland in the area -Bureau, Henry, Lee, Rock Island and Whiteside; 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, ranging from the Paleoindian Prehistoric (B.C. 10,000) to the Historic (AD. 1650), known in the assessment watershed. Volume 5, EarlyAccounts ofthe Ecology ofthe Lower RockRiverArea, describes the ecology ofthe area as recorded by historical writings of explorers, pioneers, early visitors and early historians.
