| Abstract: | THE VALUE OF THE ILLINOIS RIVER valley for waterfowl lies in its bottomland lakes that flank the relatively narrow river channel between Spring Valley and Meredosia and between Pearl and Grafton. These lakes originated in the most recent glaciation (Wisconsinan), which profoundly altered the ancient Mississippi and Illinois rivers and created the unique Illinois Valley that we find today. Up to the 1930's, the Illinois River valley was one of the nation's outstanding waterfowl hunting areas. Since then it has been in a state of decline for a variety of reasons, some of which will be discussed here. |
