Flow through the Canso Causeway / Gary L. Bugden, Brent A. Law, Edward P.W. Horne and Shawn E. Roach. : Fs97-6/3393E-PDF

"Although blocked in the 1950’s by the Canso Causeway, Canso Strait could potentially be a transport pathway for the spread of Malpeque Disease, an oyster pathogen, from the southern Gulf of Saint Lawrence to the Eastern Shore of Nova Scotia. This report describes a field program conducted from July through November of 2019 to quantify the environmental factors which could conceivably lead to trans-causeway transport.The report first characterizes the oceanographic conditions on each side of the causeway. Then an attempt is made to quantify possible transport due to each of the following mechanisms: 1) Percolation through the rock fill from which the causeway is constructed. 2) Over-topping of the causeway by wave action during storm events 3) Water passed as part of Canso Canal locking operations"--Abstract, page vi.
