Hudson Bay drainage basin, Drainage basin in northern North America.
The Hudson Bay drainage basin is a vast water system spanning multiple Canadian provinces and territories, collecting runoff from numerous rivers and lakes across the landscape. The Nelson River, its major waterway, connects Lake Winnipeg to Hudson Bay and forms the central route through which this enormous region's water flows to the ocean.
This region became the center of fur trade commerce in 1670 when a European trading company gained control of the territories surrounding Hudson Bay. This early commercial activity shaped European settlement and use of these lands for centuries to come.
For Indigenous peoples throughout the region, these waterways have always been central to daily survival and connection to the land. Today, communities continue to rely on fishing and water-based travel as they have done for generations.
The area is enormous and best explored in sections depending on where you are located or which waterways you want to visit. Visitors should prepare for harsh weather conditions and remote locations, as many parts are accessible only with proper planning and equipment.
Lake Winnipeg sits at the heart of this drainage system, acting as an enormous natural collector where waters from two separate major river systems converge. This freshwater system is so extensive that it serves as a major freshwater storage center for a vast region of North America.
