The Submerged Quay is a boat accessible fresh water dive site, located in Georgeville, QC, Canada.
The anchorage is in 4 feet of water, directly on the old quay that was used for docking carriers shuttling between New-Port and Magog. The upper part is no longer visible but the rest has remained intact.
