Lake Superior volume covers Americas 30 centimetres

Lake Superior could spread a shallow layer of water across both Americas

~30 cm deep

Lake Superior contains roughly 12,000 cubic kilometers of freshwater. If that water were spread evenly over the land area of North and South America, it would form a layer roughly 30 centimeters deep.
