Connecticut River
The Connecticut River is the longest river in New England, stretching for 410 miles from its source in New Hampshire to its mouth at Long Island Sound. The river played a significant role in the industrial development of the region, serving as a major transportation route for goods and people. Today, the river is an important source of hydroelectric power, with several large dams and reservoirs along its length, including the Moore, Wilder, and Vernon dams. The river also supports a range of recreational activities, such as fishing, boating, and hiking, and provides water for agriculture in the Connecticut River Valley. Despite decades of pollution, the river has seen significant improvements in water quality and biodiversity in recent years due to restoration efforts.
