On July 1, 1958 the St Lawrence Seaway flooded out 6,500 people & inundated 10 communities, some over 200 years old. For 50 years the murky water hid their roads, foundations, bridges & much more.
With water clarified by the zebra mussel the communities have reappeared.
The first formal Sunken Villages exhibition was at Canvas Gallery, in Toronto, ON in 2010. The next is scheduled for Sept 2013 at the Marianne Van Silfhout Gallery in Brockville, ON, Canada at St Lawrence College.
