The Aroostook River, located in Maine, is approximately 110 miles long and flows into the St. John River. The river has a rich history, being an important transportation route for Native Americans and later for lumber and agriculture industries. The hydrology of the river is influenced by the surrounding forests and wetlands, which play a critical role in regulating water flow and maintaining water quality. There are several dams and reservoirs along the river, including the Masardis Dam, which provides hydroelectric power and flood control. The river is also used for recreational activities such as fishing, kayaking, and camping. Additionally, the fertile soils along the river support agricultural production including potato farming. The Aroostook River is an important resource for both industry and recreation in the state of Maine.
