About the mill river

The Mill River is a 15-mile-long river in western Massachusetts, originating in the town of Williamsburg and flowing into the Connecticut River in Northampton. It has a rich history dating back to the early 18th century, when it was used to power mills and factories along its banks. The river's hydrology has been heavily impacted by human activities, including the construction of multiple dams and reservoirs for industrial and municipal use. Notable reservoirs include the Leeds Reservoir, the Williamsburg Reservoir, and the Hatfield Reservoir. The river also provides recreational opportunities, including fishing, kayaking, and hiking, and supports local agriculture through irrigation. Despite ongoing challenges related to water management and pollution, the Mill River remains an important natural resource for the region.
