The river is fed by several small tributaries and is also influenced by the nearby Lake Petersburg dam. Seasonal trends show high flows in the spring due to snowmelt and rainfall, and lower flows in the summer and fall. The river is also known for its diverse aquatic life, including several species of fish and mussels. Interestingly, the name "Sangamon" is derived from a Native American word meaning "where there is plenty to eat."
