Noguera Ribagorçana

The Noguera Ribagorçana or Noguera Ribagorzana is a river in northern Spain.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 at an elevation of about 2400 m, and its upper valley forms the main access route to the Aran Valley. It passes through the traditional county of Ribagorça and the town of Pont de Suert. Dams form two large reservoirs, the Escales below Pont de Suert and the Canelles above Ivars de Noguera. The Noguera Ribagorçana joins the Segre from the right at Vilanova de la Barca. It drains a basin of 2036 km2.
