The name is derived from the Malecite name Wool-ahs-took, translated by Ganong as "good river for everything". It appears as Arassatuk (DeRozier, 1699).
History
In the late 1830s, the territory comprising the river's drainage area was the scene of the Aroostook War, a boundary dispute between the United States and the United Kingdom.
The United States government maintains two river flow gages on the Aroostook. The first is located near Masardis, Maine (46°31′21″N 68°22′23″W / 46.52250°N 68.37306°W / 46.52250; -68.37306 (Masardis, Maine)) where the rivershed is 892 square miles (2,310 km). The second is at Washburn, Maine (46°46′36″N 68°09′29″W / 46.77667°N 68.15806°W / 46.77667; -68.15806 (Washburn, Maine)) where the rivershed is 1,654 square miles (4,280 km). By Fort Fairfield, Maine the rivershed is 2,301 square miles (5,960 km). At Masardis, the maximum recorded flow is 29,500 cubic feet per second (840 m/s) and the minimum 41 cubic feet (1.2 m) per second. At Washburn, the maximum recorded flow is 49,500 cubic feet (1,400 m) per second and the minimum 75 cubic feet (2.1 m) per second. Annual maximum flows occur during the spring snow melt and minimums in the fall. The highest flood levels at both gages occurred during ice-dam induced floods, which occur relatively often on this river. Such flooding occurred in March and April 1999, April and May 2003, and April 2004.
