The Nelson River is a big river. 

The Nelson River is in Canada. 

The Nelson River is in Manitoba, Canada. 

The river moves a lot of water. This helps make power for people. We call this hydroelectricity. This is power made from moving water. 
Long ago, the Cree people lived here. They called the river Powinigow. This might mean "the Rapid Strangers' river." Later, explorers came to the area. They wanted to trade furs. A man named Robert Nelson died near the river. A Welsh explorer named Sir Thomas Button named the river after him.
People once wanted to build a big port at Port Nelson. They wanted to use it for ships. But the river has too much silt. Silt is fine sand or dirt in the water. This made it hard to build. Now, Port Nelson is a ghost town. Most ships go to Churchill instead.
The Nelson River is a large river in north-central North America. It sits within the Canadian province of Manitoba. 

Moving water is a very powerful thing. The Nelson River has a huge volume of water flow. This makes it very useful for making hydroelectricity. Hydroelectricity is a way to make power from moving water. 
Long ago, the Cree people lived along the river banks. They called the river Powinigow or Powinini-gow. This name might mean "the Rapid Strangers' river." 
The river has a long history of names. A Welsh explorer named Sir Thomas Button arrived in 1612. He wintered at the mouth of the river. He named the river after a ship's master named Robert Nelson. Robert Nelson had died there. 
People once planned to build a large port at Port Nelson. They wanted ships to arrive there by rail. 

The Nelson River is a major waterway in north-central North America. It is located within the Canadian province of Manitoba. This river acts as the final drainage path for Lake Winnipeg. It carries water from the lake toward Hudson Bay. The river is a vital part of a massive water system. This system includes the Saskatchewan River, the Red River, and the Winnipeg River. 
The river follows a complex path through several different lakes. First, it flows from Lake Winnipeg into Playgreen Lake. From there, the water splits into two separate channels. The east channel and the Jack River flow through the southeast portion of the lake. They pass through Little Playgreen Lake and Pipestone Lake on the way to Cross Lake. The west channel flows from the north ends of Playgreen Lake, Kiskittogisu Lake, and Kiskitto Lake. This channel meets Cross Lake at the Jenpeg Generating Station and Dam. 
After passing Cross Lake, the water continues its journey toward the sea. It flows through Sipiwesk Lake, Split Lake, and Stephens Lake. The river also receives water from important tributaries. The Grass River drains a long area north of Lake Winnipeg. The Burntwood River also flows into the system and passes through Thompson, Manitoba. Eventually, the Nelson River empties into Hudson Bay near Port Nelson. 
History shows that the river has been important to many people. The Cree people lived along its banks long ago. They called the river Powinigow or Powinini-gow. This name may have meant "the Rapid Strangers' river." In 1612, a Welsh explorer named Sir Thomas Button arrived at the mouth of the river. He wintered there and named the river after Robert Nelson. Nelson was a ship's master who had died at that location. 
During the 1600s, the area became a site for the fur trade. In 1670, Pierre-Esprit Radisson led an expedition to the Nelson estuary. He was a French explorer and adventurer. During this trip, Charles Bayly claimed the territory for England. He nailed a brass plate with the English royal arms to a tree. A trading post called Fort Nelson was later built at the river's mouth. This post was a key site for the Hudson's Bay Company. 
The river's power is used for modern energy needs. The huge volume of water and its long drop make it useful for hydroelectricity. This is power generated from moving water. Manitoba Hydro uses dams and stations to capture this energy. However, damming the river caused flooding in the past. This led to bitter disputes with First Nations people. To help offset these damages, the Northern Flood Agreement was created in the 1970s. 
Engineers once tried to build a large port at Port Nelson. They wanted to connect the area to a North American railway grid. However, the river's geography made this very difficult. The Nelson River carries a high volume of silt. Silt is fine sand or dirt found in the water. This silt makes the water difficult to navigate. The estuary is also very broad and shallow. 
Building a port at Port Nelson would have required massive construction. Workers would have had to build artificial islands in the middle of the river. They would have needed a causeway about one kilometre long to reach deep water. Because of these practical problems, the port was relocated to Churchill. Churchill is located at the mouth of the Churchill River. Today, Port Nelson is a ghost town.
