The river has several tributaries including the Milwaukee River, Honey Creek, and Pewaukee River. The river is regulated by the Menomonee Dam, which was originally built for grist and saw mills in the 1840s. Seasonal trends include higher flow during spring snowmelt and precipitation events. The river has been restored in recent years, with the removal of the Valley Power Plant Dam in 2017 and ongoing efforts to improve water quality and aquatic habitat. Interesting facts include the river’s historical significance in the fur trade and as a transportation route for timber and wheat.
