Saint-Maurice-de-Ventalon is a land of springs, located on the watershed and consisting of three catchments. The river Luech has its spring in the uplands and joins the torrents of the Rieutort and Gourdouze before flowing into the Cèze and finally the Mediterranean. The Gardon d'Alès also has its spring here, which flows through Saint- Frézal-de-Ventalon and then to the Mediterranean. On the Atlantic side, the rivers Goudesche and Alignon calmly wind their way through meadows and into the Tarn.
