Can you guess where I took this photo? Lake Superior has a very small watershed
Lake Superior receives the least amount of surface runoff, in relation to its volume, of all five Great Lakes. This is because most of its watershed is forested, and its watershed is small, when compared to its water surface area. No major tributaries enter the lake from the south. On the Canada side, a diversion of water from the Hudson Bay watershed provides an additional input of water to the basin.
