After the La Vérendrye era and the Seven Years' War there was a steady increase in trade and commerce at the location.
Certain records refer to Fort Bas de la Rivière as the headquarters of the North West Company in the Winnipeg River basin at the time of the fur wars.
The second Fort Maurepas was built around c. 1739 on the north side of the river by some of La Vérendrye's men as part of his expansion west from Lake Superior.
Fort Bas de la Rivière was built in 1792 by Toussaint Le Sieur of the North West Company.
The forts were not proper trading posts where furs were collected but rather depots where goods were stored for shipment in either direction.
