Why is Lake Erie 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.
Is Lake Erie water safe to drink?
Back in 2014, the City of Toledo, Ohio, issued a “do not drink” advisory when treated drinking water drawn from Lake Erie contained unsafe levels of a toxin called microcystin, produced by a bloom of harmful blue-green algae. To help public drinking water managers prepare for hypoxia events, a research team led by Drs.

Why did the Edmund Fitzgerald go down?
While the Coast Guard said the cause of the sinking could not be conclusively determined, it maintained that “the most probable cause of the sinking of the S.S. Edmund Fitzgerald was the loss of buoyancy and stability resulting from massive flooding of the cargo hold.
