St. Lawrence River

The St. Lawrence River (French: Fleuve Saint-Laurent) is a big river in North America that connects the Great Lakes to the Atlantic Ocean. It flows from Lake Ontario to the Gulf of St. Lawrence, passing through parts of Canada and the United States. Some of this river forms the border between Canada and the United States.

The St. Lawrence River is very important because it carries a lot of water. It has the second most water flow of any river in North America, after the Mississippi River. The wide area where the river meets the ocean is considered the largest in the world. Along the river, you can find many natural wonders, like the many islands called the Thousand Islands, special areas where whales live, and tall rock formations known as the Mingan Archipelago.

For a long time, the St. Lawrence River has been used by people as a way to travel. It has been very important in the history of Canada and helped cities like Montreal and Quebec City grow. Today, the river is still busy with ships, thanks to a system of locks and canals called the St. Lawrence Seaway. This helps ships from all over the world reach the ports near the Great Lakes.

Etymology

The St. Lawrence River has had many names throughout history. Local First Nations gave it various names before European explorers arrived. In the 16th century, French explorers called it names like the Grand fleuve de Hochelaga and the Grande rivière du Canada.

The name we use today, St. Lawrence River, started in 1604 when explorer Samuel de Champlain wrote about it. The name comes from a bay that Jacques Cartier reached on August 10th, which was the feast day of Saint Lawrence in 1535.

Different Indigenous groups have their own names for the river. For example, the Innu-aimun call it Wepistukujaw Sipo, and the Abenaki call it Moliantegok among other names. The river is known by many special names in various Indigenous languages.

Geography

The St. Lawrence River is a big river in North America that connects the Great Lakes to the North Atlantic Ocean. It flows from Lake Ontario to the Gulf of St. Lawrence. In winter, ice forms on the river and helps ships by stopping waves and freezing.

The river runs for about 3,058 kilometres (1,900 miles) and drains a very large area. This area includes parts of Canada like Ontario and Quebec, and many states in the United States such as Minnesota, Wisconsin, Illinois, Indiana, Ohio, Pennsylvania, New York, Vermont, and Michigan. The river includes several lakes and many islands along its path.

Marine weather

In winter, the St. Lawrence River starts to freeze in December between Montreal and Quebec City. The ice moves towards the estuary and covers the entire Gulf of St. Lawrence by January and February. This ice helps ships by stopping waves and freezing.

Watershed

The St. Lawrence River was formed when the Champlain Sea drained away, after the last big ice age called the Last Glacial Maximum. Today, the river starts at the outflow of Lake Ontario and flows past many towns and cities before emptying into the Gulf of St. Lawrence. The river becomes affected by tides around Quebec City.

The St. Lawrence River runs for 3,058 kilometres (1,900 miles) from its farthest source to the ocean. Its drainage area is very large, including the Great Lakes, and covers parts of Canada and the United States. The river includes several lakes and many islands, making it an important waterway.
