The river is fed by numerous tributaries, including the Mackinaw and Spoon rivers. The Dresden Island and La Grange Lock and Dam are two notable structures on the river that can affect the flow. Seasonal trends show higher flows in the spring due to snowmelt and precipitation, while lower flows are common in the summer and fall. Interestingly, the Illinois River was once a major transportation route for trade and commerce in the Midwest. Today, it remains an important source of drinking water for many communities in Illinois.
