St. Lawrence River

The St. Lawrence is a very big river.

It flows through Canada and the United States. The water moves from the Great Lakes to the ocean.

Many animals live in the water. You can find whales and many kinds of fish.

There are also many birds near the river.

In the winter, the water can turn to ice. This ice helps big ships travel safely. The ships carry things to many cities.

People have used this river for a long time. It helps people move goods and travel. The river is a very busy place.

The St. Lawrence River is a very large river.

It sits in North America. The water flows from the Great Lakes to the Atlantic Ocean. It moves through parts of Canada and the United States.

This river is a major path for big ships. It helps move goods to many cities.

Many different animals live in these waters. You might see whales in the marine park.

There are also many kinds of fish and birds. The river has many islands, too. One group is called the Thousand Islands. Another group is the Mingan Archipelago.

In the winter, the river can freeze. Ice starts to form in December. This ice can help ships move by stopping big waves. The river has many names. Local Indigenous people have used it for a long time. French explorers also visited the river many years ago. It is a very important part of the land.

The St. Lawrence River is a huge waterway in North America.

It connects the Great Lakes to the North Atlantic Ocean. The water flows northeast from Lake Ontario toward the Gulf of St. Lawrence. This river passes through Ontario and Quebec in Canada. It also flows through New York in the United States. Some parts of the river mark the border between these two countries. It is a vital part of the earth's water systems.

This river moves a massive amount of water every second. It has the second-highest discharge in North America. Only the Mississippi River carries more water. In the whole world, it has the 16th-highest discharge. The river drains the Great Lakes Basin. This is the world's largest system of freshwater lakes. The water flows through many different lakes along the way. It passes through Lake Saint-Louis and Lake Saint-Pierre.

Many people have lived near and traveled on this river. Indigenous peoples used it as a transportation route for a long time. They gave the river many different names. For example, the Algonquin called it "the Walking Path." The Mohawk had several names for it too. Later, French explorers arrived in the 16th century. Jacques Cartier gave the region a name based on a feast day. Samuel de Champlain mapped the river in 1604. He used the name Fleuve sainct Laurens.

Nature is very busy in these waters. There are 1,864 islands in the Thousand Islands area. You can also find the limestone rocks of the Mingan Archipelago. Many living things call the river home. There are 19 species of marine mammals. You might see large whales in the Saguenay–St. Lawrence Marine Park.

There are also 230 species of birds. More than 200 kinds of fish live here. This includes 19 different types of sharks and rays.

The river is very important for modern life. It is a major path for big ships today. The St. Lawrence Seaway uses locks and canals to help them. This system lets ships reach ports inside the Great Lakes. In the winter, the river changes. Ice begins to form in December near Montreal and Quebec City. This ice can actually help ships by stopping big waves. It also keeps spray from icing up the boats.

The St. Lawrence River is a massive international waterway in North America.

It serves as the primary drainage outflow for the Great Lakes Basin. This connection allows water to flow from the Great Lakes into the North Atlantic Ocean. The river flows in a northeasterly direction. It starts at the outflow of Lake Ontario. From there, it travels through Ontario and Quebec in Canada. It also passes through New York in the United States. Parts of the river act as the official border between Canada and the U.S.

The river's massive scale is defined by its discharge, which is the volume of water flowing past a point. The St. Lawrence has the second-highest discharge in North America. Only the Mississippi River carries more water. Globally, it ranks as the 16th-highest river by discharge. Its drainage area is vast, covering 1,880,000 square kilometers. This basin includes parts of several U.S. states like Minnesota, Wisconsin, and Michigan. It also covers large portions of Ontario and Quebec. The river's journey includes several large lakes. It flows through Lake Saint-Louis and Lake Saint-Pierre.

Geologically, the river has a fascinating origin story. It formed following the draining of the Champlain Sea. This sea existed from about 13,000 to 10,000 years ago. The sea shrank as the continent rebounded after the Last Glacial Maximum. The river also sits in a seismically active zone. This means there is a risk of earthquakes. This activity is related to the Saint Lawrence rift system. These are faults linked to the opening of the ancient Iapetus Ocean. The river valley is part of the Appalachian division in the U.S. However, in Canada, it is part of the St. Lawrence Lowlands.

Indigenous peoples have used the river for transportation for a very long time. Because the river crosses many lakes, it has many different names. The Algonquin called it Magtogoek, or "the Walking Path." The Mohawk used names like Roiatatokenti or Ken’tarókwen. The Wendat Nation called it Lada8anna. European explorers arrived later in the 16th century. Jacques Cartier arrived in 1535. He named the region after the feast day of Saint Lawrence. In 1604, Samuel de Champlain mapped the river. He recorded names like Fleuve sainct Laurens.

The river is home to an incredible amount of biodiversity. The estuary and gulf support 2,200 different invertebrates. These include species like jellyfish, corals, and crustaceans. There are 19 species of marine mammals living in these waters. You can find endangered whales in the Saguenay–St. Lawrence Marine Park.

More than 230 species of birds use the river. There are also nearly 2,000 types of vascular plants. The water holds 200 species of fish. This list includes 19 different types of sharks and rays. The river also contains beautiful natural landmarks. These include the 1,864 islands of the Thousand Islands. You can also find the limestone monoliths of the Mingan Archipelago.

Modern technology allows large ships to use the river as a major shipping route. This is made possible by the St. Lawrence Seaway. The Seaway is a system of locks and canals. Locks allow ships to move between different water levels. This system connects the Great Lakes Waterway to world marine traffic. The river also undergoes seasonal changes. In December, ice begins to form near Montreal and Quebec City. The winds and currents push this ice toward the estuary. By January, ice covers the entire Gulf of St. Lawrence. Interestingly, this ice can help navigation. It prevents waves and spray from icing up the ships.
