The river's flow providers include precipitation, groundwater, and surface runoff from nearby agricultural fields. The river has several tributaries, including the North Fork Vermilion River and the Middle Fork Vermilion River. There are no major dams on the river. The river's flow is typically highest in the spring due to snowmelt and rainfall. Interesting facts about the hydrology of the Vermilion River include the presence of unique aquatic species such as the Eastern Hellbender and the Indiana Bat, and the river's historical importance as a transportation route for Native Americans and early settlers.
