Caption: Between Prince Albert and Nipawin, you have two of the most important waterways in the province of Saskatchewan, the North and South Saskatchewan rivers converge. When adding the distance, the Saskatchewan River is roughly 1,939 kilometres long. Both rivers begin in the Rocky Mountains of Alberta, through the province of Saskatchewan, and merge together to flow into Cedar Lake, Manitoba, eventually draining into Hudsons Bay. When you include its longest tributary, the Southern portion, its the fourth longest river in Canada. For good reason, this helped shape the way in which our First Nations traded, and influential for our early European exploration and trapping, forever shaping the future of the province.
