Georgian Bay Water Temperature
Georgian Bay, Ontario is on the Severn River where it meets the waters of Georgian Bay, sometimes referred to as the ‘sixth Great Lake’ but actually part of the eastern portion of Lake Huron, where Manitoulin Island to the north and the Bruce Peninsular at the south cut it off. This picturesque bay area was once part of the historic Algonquin-Huron route for trade and is part of the greater Muskoka region.
