The St.Lawrence and Great Lakes system was the most efficient route to the interior of the continent of North America. Large waterways allowed for substantial sailing vessels to trade and maintain contact with Native allies from Montreal to the Mississippi with minimal portages and transhipment in smaller boats. The one great obstacle along the chain of waterways was Niagara Falls whose dramatic height required some control of the land to allow for a portage around the escarpment and the falls to the lakes beyond. The strategic importance of this area led to the construction of several forts at the mouth of the river in an attempt to control this critical water route.
