TheGállego is a river inAragon,Spain, one of the main tributaries of theEbro River. It has a watershed of over 4,000 square kilometres (1,500 sq mi), with a total length of 193.2 kilometres (120.0 mi).
The river has its source at 2,200 metres (7,200 ft) in Col d'Aneu,Pyrenees, not far from theCol du Pourtalet. It then flows in theTena Valley through the municipalities ofSallent de Gállego,Panticosa andBiescas. Starting fromSabiñánigo it forms a wide elbow until Triste, from which it continues in its primitive north–south direction until flowing into the Ebro nearZaragoza.
The main tributaries of the Gállego in its upper basin are theAguas Limpias,Caldarés,Escarra,Lana Mayor and Aurín. In the medium and lower basin, they includeGuarga,Seco,Asabón andSotón.
The river's waters are subject to extensive regulation and derivation during its course, thus when it flows into the Ebro its discharge is just some 10 percent of its natural discharge.
This river gives its name to theAlto Gállego comarca of Aragon.
