Catchment area of the Aroostook River |
The Aroostook River [ əˈrʏstək ] is a 180 km long right tributary of the Saint John River in the US state of Maine and in the Canadian province of New Brunswick .
The Aroostook River is formed at the confluence of the Munsungan Stream and Millinocket Stream in Penobscot County in northeast Maine. The Aroostook River flows east and northeast through Aroostook County . The municipalities of Masardis , Ashland and Washburn as well as the small towns of Presque Isle and Caribou lie on the river . Major tributaries are Mooseleuk Stream , Machias River, and Little Madawaska Rivers from the left, and the Saint Croix Stream , Scopan Stream, and Presque Isle Stream from the right. The Aroostook River still passes the community of Fort Fairfield . Then it crosses the border into Canada and reaches the province of New Brunswick, where it flows into the Saint John River after 7.5 kilometers.
The region around the Aroostook River was the scene of the Aroostook War in the years 1838–1839 . This resulted in bloodless clashes between the United States and the United Kingdom of Great Britain and Ireland due to border disputes.
Hydrology
The catchment area of the Aroostook River covers 6060 km². Of this, 5957 km² are in Maine. At the gauge 3.5 km above the mouth, the mean discharge is 116 m³ / s. The months with the highest discharge are April and May with an average of 403 and 244 m³ / s.
The United States Geological Survey maintains two gauges along the river . The first measuring point is at Masardis ( ⊙ ). The catchment area of the river covers 2309 km² at this point. The highest flow rate recorded there was 600 m³ / s, the lowest 1.1 m³ / s. The second level measures data at Washburn ( ⊙ ). The catchment area at this point covers 4282 km². The highest flow rate recorded at Washburn is 1230 m³ / s, the lowest value is 2.1 m³ / s. The maximum values occur during the snowmelt in spring, the lowest water level is observed in autumn. The highest water levels caused floods caused by ice barriers at both measuring points. This happens relatively often on this river, for example in March and April 1999, in April and May 2003 or in April 2004.
