The Chicago River/Lake Shore area assessment, part of a series of statewide regional assessments, examines approximately 348 square miles in northeastern Illinois that falls within portions of two counties-- Cook and Lake. The area is defined by the watershed of the Chicago River and the areas of Cook and Lake counties that drain to Lake Michigan, excluding the area in southern Cook County that drains to the Calumet River. The report provides information on the natural and human resources of the area as a basis for managing and improving its ecosystems. The development of ecosystem-based information and management programs in Illinois are the result of three processes-- the Critical Trends Assessment Program, Conservation Congress, and Water Resources and Land Use Priorities Task Force.

Critical Trends Assessment Program : 2001 report.

Introduction: The Critical Trends Assessment Program was established in 1992 to inform state policy makers about the state of Illinois' ecosystems. During the decade since then, CTAP has developed tools and programs to systematically monitor changes in ecological conditions in Illinois. These programs not only support policymakers to help them make wise decisions about protecting our natural resources, but provide information to state and local land managers and the public as stewards of Illinois lands and waterways.
