 The catchment area of the Rivière Richelieu |

The Rivière de Richelieu (English Richelieu River ) is a right tributary of the Saint Lawrence River in the south of the Canadian province of Québec .
It rises in Lac Champlain (Lake Champlain) on the border with the US states of New York and Vermont . The 171 km long river drains an area of 23,400 km², of which 19,600 km² are accounted for by the tributaries of Lake Champlain in the USA . The confluence with the St. Lawrence River is near Sorel-Tracy , just before Lac Saint-Pierre .
The French explorer Samuel de Champlain was the first European to reach the river in 1603. Six years later he drove it along its entire length. In 1641 the French built Fort Richelieu at the estuary , named after Cardinal Richelieu . From this the name of the river was derived, which had previously been called Rivière des Iroquois (River of the Iroquois ).
In general, the river is divided into an upper and a lower part ( Le Haut-Richelieu and Le Bas-Richelieu ). The limitation is the rapids below Chambly , which the Chambly Canal bypasses. Built between 1831 and 1843, this canal is 12 miles long and part of the Lakes to Locks Passage , the continuous shipping link between the Saint Lawrence River and the Hudson River . While freight transport dominated until the first half of the 20th century, leisure transport is predominant today.
