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.
Dortmund–Ems Canal The Dortmund–Ems Canal is a 269 km long canal in Germany between the inland port of the city of Dortmund ( ) and the sea port of Emden. The artificial southern part of the canal ends after 215 km at Herbrum lock near Meppen. The route then takes the river Ems for 45 km to Oldersum lock. From there, the canal continues along a second artificial segment of 98 km . This latter section was built because inland ships at the time of the construction of the canal were not built for the open sea, which they would have faced at the Dollart and the entry to the sea port of Emden. It is connected to the Ems-Jade Canal from Emden to Wilhelmshaven.
