Water in the valley of Estang?

Around the Estang valley, there are many names of places that are linked to water. "L'estang" (étang means pond in French) lets you guess the presence of a pond that probably used to be landscaped, but that has long since dried up. The "font du Roure" reminds us that, in Provençal, "font" means "source" and not fountain. And "roure" means “oak”. The "Grand Raille" is the river at the bottom of the valley, while the "Esserennes" designates a remote place (from the village) where there would be water.
