The river is fed by several small streams and tributaries, including the Wharton Brook and Wepawaug River. It is also home to several dams, including the Hanover Pond Dam and the North Farms Reservoir Dam. Seasonal trends in water flow show higher levels during the spring and fall due to increased precipitation and snowmelt. Interestingly, the river has a history of pollution from industrial activities and has since undergone restoration efforts to improve water quality. The streamgauge is a useful tool for understanding the impact of human activities on the environment and the importance of protecting our natural resources.
