Pelee Passage lies in the western end of Lake Erie, and is the name given to the channel running through the gap created by Point Pelee and Pelee Island. Lake depths run in the 30 to 40 foot range, with the Pelee Passage Light marking the western edge of various shoals, including Grubb Reef, and Middle Ground Shoal; and the Southeast Shoal Light marking the eastern edge, about 6 miles away.
