The Noguera Ribagorzana (Spanish: [noˈɣeɾa riβaɣoɾˈθana]) or Noguera Ribagorçana (Catalan: [nuˈɣeɾə riβəɣuɾˈsanə]) is a river in northern Spain. [1]
For much of its course of 130 km it forms the administrative boundary between Catalonia and Aragon. Its source is in the municipality of Vielha e Mijaran ( Aran Valley) at an elevation of about 2400 m, and its upper valley forms the main access route to the Aran Valley (N-230 road and the Vielha tunnel (5230 m long) under the watershed). It passes through the traditional county of Ribagorza and the town of Pont de Suert ( Alta Ribagorça). Dams form two large reservoirs, the Escales below Pont de Suert and the Canelles above Ivars de Noguera ( Noguera). The Noguera Ribagorzana joins the Segre from the right at Vilanova de la Barca ( Segrià). It drains a basin of 2036 km2.
