Besides Lake Winnipeg, its primary tributaries include the Grass River , which drains a long area north of Lake Winnipeg, and the Burntwood River , which passes through Thompson, Manitoba.
The river flows into Hudson Bay near York Factory, Manitoba. Other communities upriver from there include Bird , Sundance , Long Spruce , Gillam , Split Lake , Arnot , Crosslake , and Norway House .
The lake was named by Sir Thomas Button, an English explorer 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. This has provoked bitter polemics with the First Nations of the area, whose lands past projects have flooded and future projects threaten.
