The flow of the river is typically highest during the spring due to snowmelt and spring rain, and lowest during the summer and fall. The Still River is known for its scenic beauty and recreational opportunities, including fishing and kayaking. However, it has also experienced pollution from industrial and agricultural sources, leading to efforts to improve water quality in the river.
