Tributaries of the Rhône River

The Rhône (812 km) drains the Alps and Massif Central, fed by major left- and right-bank tributaries.

Left Bank (North/West) — Alpine & Prealpine

• Ain — Jura Mountains; 200 km.
• Saône — Largest tributary (473 km); drains Burgundy, Vosges; joins at Lyon.
• Ardèche — Famous gorge (Vallon-Pont-d'Arc); 125 km.
• Cèze — Cévennes; 128 km.

Right Bank (South/East) — Massif Central & Cévennes

• Durance — Longest (324 km); main Provence river; feeds Serre-Ponçon Dam.
• Verdon — Spectacular canyon (Verdon Gorge); 166 km.
• Eygues — Drôme/Provençal; 114 km.
• Ouvèze — Two rivers: one in Drôme (93 km), one in Vaucluse (80 km).
• Ardèche — (Also listed left; enters near Pont-Saint-Esprit.)

Notes

• Saône contributes ~50% of Rhône's discharge at confluence.
• Durance/Verdon are heavily regulated for hydro/irrigation.
• Ardèche appears on both banks due to meander near mouth — technically left bank at confluence.

The Rhône's regime is nivo-pluvial (snowmelt + rain) — peak spring, low late summer.
