River system | St. Lawrence River |
The St. Lawrence River (French : Fleuve Saint-Laurent) is a large international river in the middle latitudes of North America connecting the Great Lakes to the North Atlantic Ocean. Its waters flow in a northeasterly direction from Lake Ontario to the Gulf of St. Lawrence, traversing Ontario and Quebec in Canada and New York in the United States. A section of the river demarcates the Canada–U.S. border.
As the primary drainage outflow of the Great Lakes Basin, the St. Lawrence has the second-highest discharge of any river in North America (after the Mississippi River) and the 16th-highest in the world. The estuary of St. Lawrence is often cited by scientists as the largest in the world. Significant natural landmarks of the river and estuary include the 1,864 river islands of the Thousand Islands, the endangered whales of Saguenay–St. Lawrence Marine Park, and the limestone monoliths of the Mingan Archipelago.
Long a transportation route to Indigenous peoples, the St. Lawrence River has played a key role in the history of Canada and in the development of cities such as Montreal and Quebec City. The river remains an important shipping route as the backbone of the St. Lawrence Seaway, a lock and canal system that enables world marine traffic to access the inland ports of the Great Lakes Waterway.
The river has been called a variety of names by local First Nations. Beginning in the 16th century, French explorers visited what is now Canada and gave the river names such as the Grand fleuve de Hochelaga and the Grande rivière du Canada, [8] where fleuve and rivière are two French words (fleuve being a river that flows into the sea).
The river's present name has been used since 1604 when it was recorded on a map by Samuel de Champlain [8] Champlain opted for the names Grande riviere de sainct Laurens and Fleuve sainct Laurens in his writings, supplanting the earlier names. [8] In contemporary French, the name is rendered as the fleuve Saint-Laurent. The name Saint-Laurent (Saint Lawrence) was originally applied to the eponymous bay by Jacques Cartier upon his arrival into the region on the 10th of August feast day for Saint Lawrence in 1535. [8]
Today, the river is still known by Indigenous nations by a number of distinct names. Innu-aimun, the language of Nitassinan, refers to it as Wepistukujaw Sipo/Wepìstùkwiyaht sīpu; [8] [9] the Abenaki call it Moliantegok/Moliantekw ("Montréal River"), [8] Kchitegw/Ktsitekw/Gicitegw ("Great River"), [9] or Oss8genaizibo/Ws8genaisibo/Wsogenaisibo ("River of the Algonquins"); [9] the Mohawk refer to it in Kanienʼkéha as Roiatatokenti, Raoteniateara, [8] Ken’tarókwen, [10] or Kaniatarowanénhne; [11] the Tuscarora call it Kahnawáˀkye or Kaniatarowanenneh ("Big Water Current"); [12] the Algonquins (or Omàmiwininiwak) call it "the Walking Path" or Magtogoek [8] [13] or Kitcikanii sipi, the "Large Water River"; [9] [14] the Huron-Wendats refer to it as Lada8anna or Laooendaooena; [9] and, the Atikamekw of Nitaskinan refer to it as Micta sipi ("Huge River").
In winter, the St. Lawrence River begins producing ice in December, with the formation of ice cubes between Montreal and Quebec City. The prevailing winds and currents push this ice towards the estuary, [15] and it reaches the east of Les Méchins at the end of December. Ice covers the entire Gulf of St. Lawrence in January and February.
Ice helps navigation by preventing the formation of waves, and therefore spray, and prevents the icing of ships. [16]
With the draining of the Champlain Sea, due to a rebounding continent from the Last Glacial Maximum, the St. Lawrence River was formed. The Champlain Sea lasted from about 13,000 years ago to about 10,000 years ago and was continuously shrinking during that time, a process that continues today. [17] [18] The head of the St. Lawrence River, near Lake Ontario, is home to the Thousand Islands. [19]
Today, the St. Lawrence River begins at the outflow of Lake Ontario and flows adjacent to Gananoque, Brockville, Morristown, Ogdensburg, Massena, Cornwall, Montreal, Trois-Rivières, and Quebec City before draining into the Gulf of St. Lawrence, often given as the largest estuary in the world. [20] The estuary begins at the eastern tip of Île d'Orléans, just downstream from Quebec City. [7] The river becomes tidal around Quebec City. [21]
The St. Lawrence River runs 3,058 kilometres (1,900 mi ) from the farthest headwater to the mouth and 1,197 km (743.8 mi) from the outflow of Lake Ontario. These numbers include the estuary; without the estuary, the length from Lake Ontario is c. 500 km (c. 300 mi). The farthest headwater is the North River in the Mesabi Range at Hibbing, Minnesota. Its drainage area, which includes the Great Lakes, the world's largest system of freshwater lakes, is 1,344,200 square kilometres (518,998.5 sq mi), of which 839,200 km2 (324,016.9 sq mi) is in Canada and 505,000 km2 (194,981.6 sq mi) is in the United States. The basin covers parts of Ontario and Quebec in Canada, parts of Minnesota, Wisconsin, Illinois, Indiana, Ohio, Pennsylvania, New York, Vermont, and nearly the entirety of the state of Michigan in the United States. The average discharge below the Saguenay River is 16,800 cubic metres per second (590,000 cu ft/s). At Quebec City, it is 12,101 m3/s (427,300 cu ft/s). The average discharge at the river's source, the outflow of Lake Ontario, is 7,410 m3/s (262,000 cu ft/s). [7]
The St. Lawrence River includes Lake Saint Francis at Salaberry-de-Valleyfield, Lake Saint-Louis south of Montreal and Lake Saint Pierre east of Montreal. It encompasses four archipelagoes: the Thousand Islands chain near Alexandria Bay, New York and Kingston, Ontario; the Hochelaga Archipelago, including the Island of Montreal and Île Jésus (Laval); the Lake St. Pierre Archipelago (classified a biosphere world reserve by the UNESCO in 2000) [22] and the smaller Mingan Archipelago. Other islands include Île d'Orléans near Quebec City and Anticosti Island north of the Gaspé. It is the second longest river in Canada.
Lake Champlain and the Ottawa, Richelieu, Saint-Maurice, Saint-François, Chaudière and Saguenay rivers drain into the St. Lawrence.
The St. Lawrence River is in a seismically active zone where fault reactivation is believed to occur along late Proterozoic to early Paleozoic normal faults related to the opening of the Iapetus Ocean. The faults in the area are rift-related and comprise the Saint Lawrence rift system.
According to the United States Geological Survey, the St. Lawrence Valley is a physiographic province of the larger Appalachian division, containing the Champlain section. [23] However, in Canada, where most of the valley is, it is instead considered part of a distinct St. Lawrence Lowlands physiographic division, and not part of the Appalachian division at all. [24]
The source of the North River in the Mesabi Range in Minnesota (Seven Beaver Lake) is considered to be the source of the St. Lawrence River. Because it crosses so many lakes, the water system frequently changes its name. From source to mouth, the names are:
The St. Lawrence River also passes through Lake Saint-Louis and Lake Saint-Pierre in Quebec.
The St. Lawrence River and the largest tributaries of the Great Lakes.
The St. Lawrence River tributaries are listed upstream from the mouth. The major tributaries of the inter-lake sections are also shown, as well as the major rivers that flow into the Great Lakes. Great Lakes tributaries are listed in alphabetical order.
The list includes all tributaries with a drainage area of at least 1,000 square kilometres and an average flow of more than 10 cubic metres per second.

The diversity of the St. Lawrence River includes: [27]
Large marine mammals travel in all the seas of the earth, the research and observations of these giants concern fishermen and shipping industry, exercise a fascination and a keen interest for laymen and, subjects of endless studies for scientists from Quebec, Canada and around the world. [29] [30] [31]
Thirteen species of cetaceans frequent the waters of the estuary and the Gulf of St. Lawrence: [32]
Flowing through and adjacent to numerous Indigenous homelands, the river was a primary thoroughfare for many peoples. Beginning in Dawnland at the Gulf of St. Lawrence, the river borders Mi'kma'ki [37] in the South (what is today known as the Canadian Maritimes), and Nitassinan in the North, the national territory of the Innu people. [38] On the south shore beyond the Mi'kmaw district of Gespe'gewa'ki, [37] the river passes Wolastokuk (the Maliseet homeland), Pαnawαhpskewahki (the Penobscot homeland), and Ndakinna (the Abenaki homeland). [39] Continuing, the river passes through the former country of the St. Lawrence Iroquois and then three of the six homelands of the Haudenosaunee: the Mohawk or Kanienʼkehá꞉ka, the Oneida or Onyota'a:ka, and the Onondaga or Onöñda’gaga’. [39]
In the early 17th century, the Huron-Wendat Nation migrated from their original country of Huronia to what is now known as Nionwentsïo centred around Wendake. [40] [41] Nionwentsïo occupies both the north and south shores of the river, [40] overlapping with Nitassinan and the more western Wabanaki or Dawnland countries. [39] Adjacent on the north shore is the Atikamekw territorial homeland of Nitaskinan [42] [43] and, upstream, the further reaches of Anishinaabewaki, specifically the homelands of the Algonquin and Mississauga Nations. [39]
The Norse explored the Gulf of St. Lawrence in the 11th century and were followed by fifteenth- and early sixteenth-century European mariners, such as John Cabot, and the brothers Gaspar and Miguel Corte-Real. The first European explorer known to have sailed up the St. Lawrence River itself was Jacques Cartier. At that time, the land along the river described as "about two leagues, a mountain as tall as a heap of wheat" was inhabited by the St. Lawrence Iroquoians. During Cartier's second voyage in 1535, because Cartier arrived in the estuary on Saint Lawrence's feast day 10 August, he named it the Gulf of Saint Lawrence. [44] [45]
The St. Lawrence River is today partly within the U.S. and as such is that country's sixth oldest surviving European place-name. [46]
The earliest regular Europeans in the area were the Basques, who came to the St Lawrence Gulf and River in pursuit of whales from the early 16th century. The Basque whalers and fishermen traded with indigenous Americans and set up settlements, leaving vestiges all over the coast of eastern Canada and deep into the St. Lawrence River. Basque commercial and fishing activity reached its peak before the Armada Invencible's disaster (1588), when the Basque whaling fleet was confiscated by King Philip II of Spain. Initially, the whaling galleons from Labourd were not affected by the Spanish defeat.
Until the early 17th century, the French used the name Rivière du Canada to designate the St. Lawrence upstream to Montreal and the Ottawa River after Montreal. The St. Lawrence River served as the main route for European exploration of the North American interior, first pioneered by French explorer Samuel de Champlain.
Control of the river was crucial to British strategy to capture New France in the Seven Years' War. Having captured Louisbourg in 1758, the British sailed up to Quebec the following year thanks to charts drawn up by James Cook. British troops were ferried via the St. Lawrence to attack the city from the west, which they successfully did at the Battle of the Plains of Abraham. The river was used again by the British to defeat the French siege of Quebec under the Chevalier de Lévis in 1760.
In 1809, the first steamboat to ply its trade on the St. Lawrence was built and operated by John Molson and associates, a scant two years after Fulton's steam-powered navigation of the Hudson River. The Accommodation with ten passengers made her maiden voyage from Montreal to Quebec City in 66 hours, for 30 of which she was at anchor. She had a keel of 75 feet, and a length overall of 85 feet. The cost of a ticket was eight dollars upstream, and nine dollars down. She had berths that year for twenty passengers. [47] Within a decade, daily service was available in the hotly-contested Montreal-Quebec route. [48]
Because of the virtually impassable Lachine Rapids, the St. Lawrence was once continuously navigable only as far as Montreal. Opened in 1825, the Lachine Canal was the first to allow ships to pass the rapids. An extensive system of canals and locks, known as the St. Lawrence Seaway, was officially opened on 26 June 1959 by Elizabeth II (representing Canada) and President Dwight D. Eisenhower (representing the United States). The Seaway (including the Welland Canal) now permits ocean-going vessels to pass all the way to Lake Superior. [49]
During the Second World War, the Battle of the St. Lawrence involved submarine and anti-submarine actions throughout the lower St. Lawrence River and the entire Gulf of St. Lawrence, Strait of Belle Isle and Cabot Strait from May to October 1942, September 1943, and again in October and November 1944. During this time, German U-boats sank several merchant marine ships and three Canadian warships.
In the late 1970s, the river was the subject of a successful ecological campaign (called "Save the River"), originally responding to planned development by the United States Army Corps of Engineers. The campaign was organized, among others, by Abbie Hoffman. [50]
The St. Lawrence Seaway is a system of locks, canals, and channels in Canada and the United States that permits oceangoing vessels to travel from the Atlantic Ocean to the Great Lakes of North America, as far inland as Duluth, Minnesota, at the western end of Lake Superior. The seaway is named for the St. Lawrence River, which flows from Lake Ontario to the Atlantic Ocean. Legally, the seaway extends from Montreal, Quebec, to Lake Erie, and includes the Welland Canal. Ships from the Atlantic Ocean are able to reach ports in all five of the Great Lakes, via the Great Lakes Waterway.

Anticosti is an island located between the Jacques Cartier and Honguedo Straits, in the Gulf of St. Lawrence, in L'Île-d'Anticosti (Municipality), Minganie MRC, Côte-Nord, Quebec, Canada.
The Saguenay–St. Lawrence Marine Park is a National Marine Conservation Area, one of three in the Canadian national park system, located where the Saguenay River meets the Maritime estuary of the St. Lawrence River. This park is jointly managed by Parks Canada and Sépaq. It is the first park in all of Canada to protect a purely marine environment, and covers a surface area of 1,245 km2. The area that is now the Saguenay–St. Lawrence Marine Park is a part of the Innue Essipit First Nation's land claim, and a treaty resulting from this claim could impact activities that are practiced within the park. The region surrounding the park is an important part of the history of Canada, being one of the first points of contact between Indigenous Peoples and European explorers and the birthplace of the intercontinental fur trade.
Lake Saint Pierre is a lake in Quebec, Canada, a widening of the Saint Lawrence River between Sorel-Tracy and Trois-Rivières. It is located downstream, and northeast, of Montreal; and upstream, and southwest, of Quebec City. The end of the lake delimits the beginning of the estuary of Saint Lawrence.
Located in the eastern part of Canada, and part of Central Canada, Quebec occupies a territory nearly three times the size of France or Texas. It is much closer to the size of Alaska. As is the case with Alaska, most of the land in Quebec is very sparsely populated. Its topography is very different from one region to another due to the varying composition of the ground, the climate, and the proximity to water. The Great Lakes–St. Lawrence Lowlands and the Appalachians are the two main topographic regions in southern Quebec, while the Canadian Shield occupies most of central and northern Quebec.
Minganie is a regional county municipality on the north shore of the Gulf of St. Lawrence, in Côte-Nord region, Quebec, Canada, its territory includes Anticosti Island.
Canada was a French colony within the larger territory of New France. It was claimed by France in 1535 during the second voyage of Jacques Cartier, in the name of the French king, Francis I. The colony remained a French territory until 1763, when it became a British colony known as the Province of Quebec.

The St. Lawrence Iroquoians were an Iroquoian Indigenous people who existed until about the late 16th century. They concentrated along the shores of the St. Lawrence River in present-day Quebec and Ontario, Canada, and in the American states of New York and northernmost Vermont. They spoke Laurentian languages, a branch of the Iroquoian family.
The Great Lakes-St. Lawrence Lowlands, or simply St. Lawrence Lowlands, is a physiographic region of Eastern Canada that comprises a section of southern Ontario bounded on the north by the Canadian Shield and by three of the Great Lakes — Lake Huron, Lake Erie and Lake Ontario — and extends along the St. Lawrence River to the Strait of Belle Isle and the Atlantic Ocean. The lowlands comprise three sub-regions that were created by intrusions from adjacent physiographic regions — the West Lowland, Central Lowland and East Lowland. The West Lowland includes the Niagara Escarpment, extending from the Niagara River to the Bruce Peninsula and Manitoulin Island. The Central Lowland stretches between the Ottawa River and the St. Lawrence River. The East Lowland includes Anticosti Island, Îles de Mingan, and extends to the Strait of Belle Isle.

In the regions of Saguenay–Lac-Saint-Jean, Charlevoix, Côte-Nord, and Bas-Saint-Laurent, the park is situated along the eastern end of the Saguenay River and adjoins the Saguenay–St. Lawrence Marine Park for over 100 km (60 mi.).
The Champlain Sea was a prehistoric inlet of the Atlantic Ocean into the North American continent, created by the retreating ice sheets during the closure of the last glacial period. The inlet once included lands in what are now the Canadian provinces of Quebec and Ontario, as well as parts of the American states of New York and Vermont. Today, the remains of the sea include the St. Lawrence Seaway, Lake Champlain, Lake of Two Mountains on the lower Ottawa River, the lower Saguenay River, as well as other lakes, islands and shores.
SS Brulin was a lake freighter that worked the North American Great Lakes routes from 1924 to 1960. She was renamed Outarde in 1939, and James J. Buckler in 1960, shortly before she ran aground and sank during salvage operations. Brulin was built by Palmers Shipbuilding and Iron Company, Hebburn-on-Tyne and launched on 31 July 1924, for the Montreal Forwarding Company. She was built to the maximum dimensions of the canal locks that preceded the St Lawrence Seaway.
St. Lawrence River Estuary stretches from west to east for 655 km, from the outlet of Lake Saint Pierre to Pointe-des-Monts, where it becomes the Gulf of St. Lawrence, in Quebec, Canada.
The area represents one of the largest and most productive estuarine/marine ecosystems in Canada and in the world.
If you consider that both water and air masses literally hug the ground and follow all its contours and surfaces, it's easy to understand just how much variety there can be in wind and sea conditions.

We fear that the increase in maritime traffic, facilitated by climate change, is modifying the nature of the acoustic environment of the population. This population can correspond, or almost corresponds, to the criteria of the category "species threatened »
The population of St. Lawrence belugas is relatively sedentary given that the most distant seasonal areas are not separated only by a few hundred kilometers
Since 1998, several sightings of right whales have also been reported elsewhere in the St. Lawrence: Magdalen Islands, Baie des Chaleurs, Basse-Côte-Nord and the St. Lawrence estuary, in the Saguenay—St. Lawrence Marine Park.
Today, the biggest threats for this species come from ship strikes, disturbance from increasing whale watch activity, entanglement in fishing gear, and pollution.
The first steamship to operate on the St Lawrence River was John Molson's wooden paddle steamer Accommodation, built in Montreal in 1809.
According to a special report compiled by BMO Capital Markets, the eight states and two provinces that border the Great Lakes/St. Lawrence Seaway System generate an immense economic impact within North America.
