Mille Roches Power House (1901) at Cornwall was demolished prior to inundation in 1955 with the new powerdam and seaway nearing completion. In some locations, a few remnants of sidewalks and building foundations can still be seen under the water, or even on the shoreline when water levels are sufficiently low. In 2013, the photographer Louis Helbig documented the presence of some of these features using aerial photography. Some high points of land in the flooded area remained above water as islands, and are connected by the Long Sault Parkway.
