Major constituents include nitrates, phosphates, and suspended sediment, which can lead to water quality issues downstream. The river has several tributaries, including the Mullet River and Onion River, and is dammed at several locations. Seasonal trends show frequent flooding in spring due to snowmelt and heavy rainfall, while summer months typically have lower flow rates. An interesting fact about the hydrology of the Sheboygan River is that it has been the site of several successful brown trout and steelhead restoration projects.
