The Bouès is a right tributary of the Arros, at the eastern end of the basin of the Adour, in the Southwest of France. It is 63km (39miles) long.
The Bouès rises near Capvern, west of Lannemezan where it is fed by the Neste Canal. It flows north through a narrow valley and joins the Arros, downstream from Marciac, in a historical region known as Rivière-Basse.
