Mousam River
The Mousam River is a 29-mile-long river in southern Maine that flows from its headwaters in Shapleigh to its mouth at Kennebunkport. The river has a rich history, having served as a source of power for early mills and factories. Today, it is used for recreational activities like fishing, boating, and swimming. The river's hydrology is heavily influenced by precipitation and snowmelt, and it can experience significant flooding during periods of heavy rain. The river is also home to several reservoirs and dams, including the Upper and Lower Mousam Dams, which were built to regulate water flow and generate hydroelectricity. These reservoirs provide drinking water for several communities in the region. Additionally, the river is used for irrigation to support local agriculture.
