Гав-де-По
The commune lies in the Drainage basin of the Adour and the Gave de Pau flows through the south-western edge of the commune with the "Ruisseau de Clamonde" flowing into it from the commune. Paul Raymond mentioned in 1863 that the Juren, a stream with its source in Arthez-de-Béarn, crossed Aragnon and flowed into the Gave de Pau
