The St. Lawrence Seaway is protected from seawater intrusion primarily by a series of locks and dams that regulate water levels and flow. These structures create a freshwater navigation channel, allowing vessels to transit between the Great Lakes and the Atlantic Ocean without mixing seawater with freshwater. Additionally, the natural geography and freshwater flow of the Great Lakes contribute to maintaining the separation between the two bodies of water.
