St. Lawrence River

Etymology

The river has historically been given a variety of different 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, 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. Champlain opted for the names Grande riviere de sainct Laurens and Fleuve sainct Laurens in his writings, supplanting the earlier names. 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.

Indigenous people use the following names:

• Innu-aimun, the language of Nitassinan, refer to it as Wepistukujaw Sipo/Wepìstùkwiyaht sīpu.
• the Abenaki call it Moliantegok/Moliantekw ("Montréal River"), Kchitegw/Ktsitekw/Gicitegw ("Great River"), or Oss8genaizibo/Ws8genaisibo/Wsogenaisibo ("River of the Algonquins").
• in Mohawk language it is Roiatatokenti, Raoteniateara, Ken’tarókwen, or Kaniatarowanénhne.
• Tuscarora people call it Kahnawáˀkye or Kaniatarowanenneh ("Big Water Current").
• Algonquin people call it "the Walking Path" or Magtogoek, or Kitcikanii sipi, the "Large Water River".
• the Wendat Nation call it Lada8anna or ''Laooendaooena'''.
• the Atikamekw of Nitaskinan refer to it as Micta sipi ("Huge River").

Geography

Marine weather

In winter, the St. Lawrence River begins producing ice in December between Montreal and Quebec City. The prevailing winds and currents push this ice towards the estuary, 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.

Watershed

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. The head of the St. Lawrence River, near Lake Ontario, is home to the Thousand Islands.

Today, the St. Lawrence River begins at the outflow of Lake Ontario and flows adjacent to Cape Vincent, Gananoque, Clayton, Alexandria Bay, 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. The estuary begins at the eastern tip of Île d'Orléans, just downstream from Quebec City. The river becomes tidal around Quebec City.

The St. Lawrence River runs 3058 km from the farthest headwater to the mouth and 1197 km 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 1344200 km2, of which 839200 km2 is in Canada and 505000 km2 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 16800 m3/s. At Quebec City, it is 12101 m3/s. The average discharge at the river's source, the outflow of Lake Ontario, is 7410 m3/s.

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) 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. 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.

Sources

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:

• North River
• Saint Louis River
• Lake Superior
• St. Marys River
• Lake Huron
• St. Clair River
• Lake St. Clair
• Detroit River
• Lake Erie
• Niagara River
• Lake Ontario

The St. Lawrence River also passes through Lake Saint-Louis and Lake Saint-Pierre in Quebec.

Tributaries

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.

Biodiversity

The diversity of the St. Lawrence River includes:

• 19 species of marine mammals
• More than 230 species of birds
• Nearly 35 species of amphibians and reptiles
• 200 species of freshwater and saltwater fish (including 19 sharks and rays)
• 2200 invertebrates in the estuary and its gulf (sponges, jellyfish, corals, crustaceans, etc.)
• Nearly 2000 vascular plants

Marine mammals

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.

Thirteen species of cetaceans frequent the waters of the estuary and the Gulf of St. Lawrence:

1. Northern bottlenose whale
2. Delphinapterus leucas (Beluga Whale)
3. Sperm whale
4. Atlantic white-sided dolphin
5. White-beaked dolphin
6. Orca
7. Long-finned pilot whale
8. Phocoena phocoena (Harbour Porpoise)
9. North Atlantic right whale
10. Common minke whale
11. Blue whale
12. Humpback whale
13. Fin whale

History

First Nations

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 in the South (what is today known as the Canadian Maritimes), and Nitassinan in the North, the national territory of the Innu people. On the south shore beyond the Mi'kmaw district of Gespe'gewa'ki, the river passes Wolastokuk (the Maliseet homeland), Pαnawαhpskewahki (the Penobscot homeland), and Ndakinna (the Abenaki homeland). 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’.

In the early 17th century, the Wendat Nation migrated from their original country of Huronia to what is now known as Nionwentsïo centred around Wendake. Nionwentsïo occupies both the north and south shores of the river, overlapping with Nitassinan and the more western Wabanaki or Dawnland countries. and, upstream, the further reaches of Anishinaabewaki, specifically the homelands of the Algonquin and Mississauga Nations.

European exploration

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. | access-date=2011-02-27 }}

The St. Lawrence River is today partly within the U.S. and as such is that country's sixth oldest surviving European place-name.

Early colonists

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.

Colonial control

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. Within a decade, daily service was available in the hotly-contested Montreal-Quebec route.

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.

Modern Canada

Alcoa, Reynolds Metals Company, and General Motors (GM) Central Foundry operated along the St. Lawrence River and its tributaries for decades. The Alcoa plant opened in 1903, and Reynolds and GM began operations in the late 1950s. These facilities released toxic substances into the St. Lawrence River and the surrounding area, including PCBs, PAHs, cyanide, fluoride, and dioxins.

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.
