Arga (river)
The Arga is a river of Navarre, in Spain, and is a tributary of the Aragón River, itself a tributary of the river Ebro. The Arga was known as the river Runa in antiquity. Situated in the north-east of Spain, the river stretches some 145 kilometres (90 mi) and has a basin of 2,759 square kilometres (1,065 sq mi), of which 2,652 square kilometres (1,024 sq mi) is in Navarre and the remaining 107 square kilometres (41 sq mi) is in the province of Alava. The source of the river is to the north of the village Esteríbar, near the border with France, and it empties into the Aragón River near Funes.
