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.
Seine–Nord Europe Canal The Seine–Nord Europe Canal is a projected high-capacity ("grand gabarit") canal in France that would link the Oise River at Compiègne with the Canal Dunkerque-Escaut, east of Arleux. The objective is to expand trade flows in a fuel-efficient and ecologically friendly manner between the Seine basin and Belgium, Germany and the Netherlands, while reducing saturation on the A1 motorway in France and reducing the CO2 emissions in the transport sector within this corridor.
