And when the lake is already high, that may mean ferries to the islands can’t run because they can’t safely load cars or passengers. All the Great Lakes have high water levels right now. That’s because about 92 percent of the water in Lake Erie comes from the upper lakes, through the Detroit River, into Lake Erie.

Why is Lake Erie water so high?
Water levels change very quickly on Lake Erie because it’s so small and shallow, Mackey said. High water intensifies a natural effect called a seiche, a change in water level across the lake because of wind or atmospheric pressure. Winds across Lake Erie can mean a 10-foot difference between Toledo and Buffalo.
Do the Great Lakes freeze?
Yet they do experience substantial ice coverage, with large sections of the lake freezing over in the coldest months.

In that time, the lakes have surpassed 80% ice coverage a mere five times.
