The river is primarily fed by precipitation and stormwater runoff, but also receives some flow from the Skokie River and other smaller tributaries. During the winter months, water levels typically decrease due to reduced precipitation and increased evaporation. In the spring, water levels can rise due to snowmelt and increased rainfall. The river has several small dams, but their impact on water flow is minimal. One interesting fact about the North Branch Chicago River is that it was once heavily polluted, but has since undergone significant restoration efforts to improve water quality and wildlife habitat.
