The river receives water from several tributaries, including the Chicopee River and the Westfield River. The Enfield Dam, located upstream of Thompsonville, can regulate the flow of the river, causing it to fluctuate. During the spring, the river tends to have higher flows due to snowmelt. In the summer, flows decrease and are typically more stable. In the fall, flows can increase due to heavy rainstorms. Interestingly, the Connecticut River is known for being the longest river in New England, stretching over 400 miles from its source in New Hampshire to the Long Island Sound.
