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 mi2), of which 2,652 square kilometres (1, 024 mi2) is in Navarre and the remaining 107 square kilometres (41 mi2) 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. The river is dammed in the Eugui reservoir near Esteríbar; the dam principally serves the needs of Pamplona's metropolitan area, the largest city on the Arga.
