Originally published in 1912, this report from the Chicago Sanitary District Board of Trustees provides a detailed examination of the Illinois River and its use as a commercial waterway. The report includes analysis of the river's physical properties, such as geography and hydrology, as well as an evaluation of the navigation dams that were constructed to aid in transportation. A supplementary section provides information on the Sanitary and Ship Canal of Chicago and its impact on the regional water system. The report is a valuable resource for engineers, urban planners, and anyone interested in the history and management of freshwater resources.
