Aragón (river)
The Aragón is a river in northern Spain, one of the left-hand tributaries of the river Ebro. It rises at Astún in the central Pyrenees Mountains, passes southwest through Jaca and Sangüesa, and joins the Ebro at Milagro, near Tudela. The name Aragón is related to the birth area of the former kingdom, which corresponds to the modern autonomous community of Aragón in Spain.Watershed
The river, used for irrigation and hydroelectric power, is about long; its chief tributary is the Arga River.
Ecology
Non-government sanctioned re-introduction of Eurasian beaver in Spain around 2003 has resulted in tell-tale beaver signs documented on a stretch on the lower course of the Aragon River and the area adjoining the Ebro River in Aragon, Spain.
