Les rivières du Jabron et du Vermenon

La Bâtie Rolland, surrounded by its two rivers, the Jabron and the Vermenon, is set in lush greenery, inviting you to stroll and relax.

Like the Roubion, the Jabron is a moderately abundant river. The annual runoff in the river's watershed is 235 millimeters, which is well below the French average for all watersheds combined. The Jabron is a natural, non-navigable watercourse 38.92 km long. It rises in the commune of Comps and flows into Le Roubion in the commune of Montélimar.

The Vermenon is a non-navigable natural waterway 16.59 km long. It rises in the commune of Salettes and flows into Le Jabron in the commune of Montboucher-sur-jabron.

Montélimar-Agglomération is responsible for the development, management and maintenance of non-navigable watercourses of community interest.
