Mill River Flood Control System



The Mill River Flood Control System consists of two levee sections. The Smith College Levee is located along the east bank of the Mill River between Paradise Pond Dam and West Street. The Diversion Levee extends from the Manhan Rail Trail to Hebert Avenue. Combined, these two sections of levee are approximately 1,900 feet in length with a maximum height of 25 feet.

Between the two levee sections is a concrete floodwall that extends for approximately 450 feet. This system diverts the Mill River from its original channel, through Veterans Field and behind City Hall, into a 10,500 foot long diversion channel which empties into the Oxbow at the Connecticut River. Other features of the Mill River System include a stop log closure structure, a small pumping station, a drop structure, and a concrete bridge located upstream from the Connecticut River Oxbow at Old Springfield Road.
