Water features on the Canal du Midi
(Redirected from
Déversoir de Marseillette
)The balancing of incoming and outgoing water allows the
Pierre Paul Riquet
, its creator.
In the canal's original configuration of 1687, water was provided by the
River Sor and from the Bassin de Saint-Ferréol. The Bassin de Lampy was added later. Since the drought of 1989–1990, water can also be made available from the Lac de Montbel.[1]
Water leaving the canal between locks, will exit through either a weir (French: déversoir) or a siphon (French: Épanchoir). Leaving through the weir, the water simply flows over the side of the canal via a stone or concrete ledge. If the water reaches a specific level, it may be siphoned off via a stone siphon.

| WS | 116.5 | l'Orbiel | Not sure exactly what this is. The reference[1] shows the stream l'Orbiel splitting north of the canal. One side of the stream joins the canal and the other goes under the canal via the Orbiel Aqueduct. So, it could either be a source of water or a release path. The reference[2] calls it the French: canal d'alimentation d'Orbiel and the canal vieux. | |
