Saint Regis is a hamlet at the confluence of the St. Regis River and a seaway which legally includes what canal?
Saint Lawrence Seaway The Saint Lawrence Seaway (French: "la Voie Maritime du Saint-Laurent" ) is a system of locks, canals and channels in Canada and the United States that permit ocean-going vessels to travel from the Atlantic Ocean to the Great Lakes of North America, as far inland as the western end of Lake Superior. The Seaway is named for the Saint Lawrence River, which flows from Lake Ontario to the Atlantic Ocean. Legally, the Seaway extends from Montreal, Quebec, to Lake Erie and includes the Welland Canal.
Breachway A breachway is defined as the shore along a channel. Today the term is used to describe the whole area around where a channel meets the ocean. The Rhode Island coastline has many breachways on its map. Today's permanent breachways have rock jetties that line the sides of the channel to protect against erosion or closing of the waterway. The water channels usually lead to salt water ponds.
