The great lakes hold 20% of the world"s fresh water. Compared to the ocean, the lakes are more choppy and thus more dangerous: waves up to 40ft.

Seiche - rapid change in water levels due to wind and/or barometric pressure: bathtubish effect, around a 2. 5ft drop. They create their own weather: when the cold air hits the warmer water it will cause snow, temperature modulation models a tiny ocean. Invasive species: a lot of resource extraction from around the great lakes. Logging in 1800s - shipping through the st. lawrence.
