The river is fed by several tributaries, including the Oak Creek and the Kinnickinnic River, and is home to several dams that can affect flow rates. Seasonal trends show that the river typically experiences higher flow rates in the spring due to snowmelt and rainfall, while summer months tend to have lower flow rates. Interesting facts about the hydrology of the river include its designation as a "Class I trout stream," which means it supports a self-sustaining population of trout, and its role as an important source of water for the surrounding communities.
