The Bassin de Saint-Ferréol (
The dam has a crest length of 780 m (2,560 ft), a maximum height of 32 m (105 ft), and a base thickness of more than 140 m (450 ft). Water may be drawn from the reservoir via a stone vaulted tunnel that penetrates the base of the dam. Silt can be removed from the floor of the reservoir through the tunnel. When filled to capacity, the reservoir contains some 680,000 cubic metres (180×106 US gal) of water.[1]
Originally, the basin was to be fed by only the River Laudot. When this was deemed to be insufficient, other streams fed into what Riquet called the "
The entrance of the Laudot into the basin is split so that one portion goes into the basin and the other portion diverts around the basin and returns to the Laudot downstream of the dam. The waters released from the dam follow the downstream route of the Laudot until they join with the rigole de la plaine at Les Thoumazes. The waters continue to the Bassin de Naurouze before entering the canal itself.[1]

The lake lies in the three communes of Vaudreuille (Haute-Garonne), Les Brunels (Aude) and Sorèze (Tarn).
