Ezka
River in the Basque Country.
The Ezka river (in Spanish: Esca) is a tributary of the Aragon river that flows along 51 kilometers, mainly through the region of Navarra and to a lesser extent (14 kilometers) through Aragon (province of Zaragoza). It rises at the junction of the Belagua and Uztárroz rivers in the Navarre town of Isaba (Roncal Valley) and flows south through the valley to its mouth at the Yesa Reservoir, downstream from the Aragonese town of Sigüés (La Jacetania).[1][2]
