Do both The Portage Canal and Erie Canal allow connection to the Atlantic Ocean ?
Erie Canal The Erie Canal is a canal in New York that is part of the east–west, cross-state route of the New York State Canal System (formerly known as the New York State Barge Canal). Originally, it ran 363 mi from Albany, on the Hudson River, to Buffalo, at Lake Erie. It was built to create a navigable water route from New York City and the Atlantic Ocean to the Great Lakes. When completed in 1825, it was the second longest canal in the world (after the Grand Canal in China) and greatly affected the development and economy of New York, New York City, and the United States.
Elbląg Canal Elbląg Canal ( , Polish: "Kanał Elbląski" , German: "Oberländischer Kanal" ) is a canal in Poland, in Warmian-Masurian Voivodeship, 80.5 km in length, which runs southward from Lake Drużno (connected by the river Elbląg to the Vistula Lagoon), to the river Drwęca and lake Jeziorak. It can accommodate small vessels up to 50 tons displacement. The difference in water levels approaches 100 m, and is overcome using locks and a remarkable system of inclined planes between lakes.
