The Nelson River is a river of north-central North America, in the Canadian province of Manitoba. Its full length is 2,575 kilometres (1,600 mi), it has mean discharge of 2,370 cubic metres per second (84,000 cu ft/s), and has a drainage basin of 892,300 square kilometres (344,500 sq mi), of which 180,000 square kilometres (69,000 sq mi) is in the United States. The river drains Lake Winnipeg and runs 644 kilometres (400 mi) before it ends in Hudson Bay.
Since it drains Lake Winnipeg, it is the last part of the large Saskatchewan River system, as well as that of the Red River and Winnipeg River. Devils Lake is unusual for a glacial lake in being presently closed, also has been known to overflow into the Red River for at least five separate periods since deglaciation.
The river flows into Hudson Bay at Port Nelson (now a ghost town), just north of the Hayes River and York Factory. Other communities upriver from there include Bird, Sundance, Long Spruce, Gillam, Split Lake, Arnot, Cross Lake, and Norway House.
The river was named by Sir Thomas Button, a Welsh explorer from St. Lythans, Glamorganshire, who wintered at its mouth in 1612, after Robert Nelson, a ship's master who died there. The area was fought over for the fur trade, though the Hayes River, whose mouth is near the Nelson's, became the main route inland.
Today, the Nelson River's huge volume and long drop make it useful for generating hydroelectricity. Flooding caused by damming of the river has provoked bitter disputes with First Nations in the past although the Northern Flood Agreement was created in the 1970s to help offset the damages caused by flooding.
Fort Nelson, a historic Hudson's Bay Company trading post, was located at the mouth of the Nelson River at Hudson Bay and was a key trading post in the early 18th century. After his pivotal role in establishing the Hudson's Bay Company, Pierre Esprit Radisson, noted French explorer, was chief director of trade at Port Nelson during one of his sustained periods of service to England. Today, Port Nelson no longer exists. Port Nelson, the abandoned shipping port remains on the opposite side of the river mouth on Hudson Bay.
