The ****Aigues, Aigue, Aygues or Eygues (Occitan: Éguer) is a French river, a tributary of the Rhône. It runs through the departments of Drôme, Hautes-Alpes and Vaucluse. Its source is in the Baronnies mountains. It flows through Verclause, Sahune, Nyons, and it flows into the Rhône at Caderousse. It is 113.7 km long. Its drainage basin is 1012 km2. Several spellings of the name are in use: the French national map service Géoportail shows both "l'Aigues" and "l'Aygues" on maps of the same area near Orange, and the village name of Saint-Maurice-sur-Eygues preserves another variant. Among its tributaries is the Lauzon.
