Title:Some Recent Changes in Illinois River Biology
Author(s):Forbes, Stephen Alfred; Richardson, R.E.
Subject(s):Illinois River Biology
drainage canal
Sanitary District of Chicago
Abstract:The principal cause of change in the biological environment of the Illinois River which have come in since 1899 are the opening of the drainage canal of the Sanitary District of Chicago in January 1900, a great increase in the amount of Chicago sewage emptied into the stream, and an extensive reclamation of the river bottoms for agricultural uses; and it is our present purpose to trace the principal effects of these changes upon the life of the stream. Although this study has had primarily a purely scientific motive, it has bearings of a practical character which we have followed out in some cases beyond the boundaries of our proper inquiry, with a view to making our results available, or at least suggestive, to those who have to deal with problems of sewage disposal, fisheries, bottom-land agriculture, and the like.
