What to watch in Lake Erie

Lake Erie is the shallowest Great Lake, which makes it the fastest to turn dangerous: northwesterly winds can stack steep 4–6 ft seas in the western basin within hours, and wind-driven seiches shift water levels several feet end to end. Watch wind speed and direction closely and check the buoy in your basin.
