The current from the Richelieu River arrives from the southeast by crossing the Chambly rapids for a length of approximately 1.35 kilometres (0.84 mi), i.e. downstream from the Yule bridge which spans this river in order to connect Chambly (west bank) and Richelieu (east bank).

These rapids end at the height of an archipelago of small islands bordering the south-eastern shore of the basin.

The Rivière des Hurons flows toward the middle of the eastern shore of the basin.

[2] In Jesuit Relations of 1665, we read: "This basin is like a small lake, a league and a half of a turn, six to eight feet deep.

[4] The name French: Bassin de Chambly was formalized by the Quebec Commission of Geography in 1968.
