The Great Lakes, also called the Great Lakes of North America, are a series of large interconnected freshwater lakes in the east-central interior of North America that connect to the Atlantic Ocean via the Saint Lawrence River. The five lakes are Superior, Michigan, Huron, Erie, and Ontario and are in general on or near the Canada–United States border. Hydrologically, Michigan and Huron are a single body of water joined at the Straits of Mackinac. The Great Lakes Waterway enables modern travel and shipping by water among the lakes.
The St. Lawrence Seaway is a system of locks, canals, and channels in Canada and the United States that permits oceangoing vessels to travel from the Atlantic Ocean to the Great Lakes of North America, as far inland as Duluth, Minnesota, at the western end of Lake Superior. The seaway is named for the St. 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. Ships from the Atlantic Ocean are able to reach ports in all five of the Great Lakes, via the Great Lakes Waterway.
The St. Lawrence River is a large international river in the middle latitudes of North America connecting the Great Lakes to the North Atlantic Ocean. Its waters flow in a northeasterly direction from Lake Ontario to the Gulf of St. Lawrence, traversing Ontario and Quebec in Canada and New York in the United States. A section of the river demarcates the Canada–U.S. border.
A waterway is any navigable body of water. Broad distinctions are useful to avoid ambiguity, and disambiguation will be of varying importance depending on the nuance of the equivalent word in other languages. A first distinction is necessary between maritime shipping routes and waterways used by inland water craft. Maritime shipping routes cross oceans and seas, and some lakes, where navigability is assumed, and no engineering is required, except to provide the draft for deep-sea shipping to approach seaports (channels), or to provide a short cut across an isthmus; this is the function of ship canals. Dredged channels in the sea are not usually described as waterways. There is an exception to this initial distinction, essentially for legal purposes, see under international waters.
The Trent–Severn Waterway is a 386-kilometre-long (240 mi) canal route connecting Lake Ontario at Trenton to Georgian Bay, Lake Huron, at Port Severn. Its major natural waterways include the Trent River, Otonabee River, Kawartha Lakes, Lake Simcoe, Lake Couchiching and Severn River. Its scenic, meandering route has been called "one of the finest interconnected systems of navigation in the world".
The St. Marys River, sometimes written St. Mary's River, drains Lake Superior, starting at the end of Whitefish Bay and flowing 74.5 miles (119.9 km) southeast into Lake Huron, with a fall of 23 feet (7.0 m). For its entire length it is an international border, separating Michigan in the United States from Ontario, Canada.
The Welland Canal is a ship canal in Ontario, Canada, and part of the St. Lawrence Seaway and Great Lakes Waterway. The canal traverses the Niagara Peninsula between Port Weller on Lake Ontario, and Port Colborne on Lake Erie, and was erected because the Niagara River—the only natural waterway connecting the lakes—was unnavigable due to Niagara Falls. The Welland Canal enables ships to ascend and descend the Niagara Escarpment, and has followed four different routes since it opened.
The Soo Locks are a set of parallel locks, operated and maintained by the United States Army Corps of Engineers, Detroit District, that enable ships to travel between Lake Superior and the lower Great Lakes. They are located on the St. Marys River between Lake Superior and Lake Huron, between the Upper Peninsula of the U.S. state of Michigan and the Canadian province of Ontario. They bypass the rapids of the river, where the water falls 21 ft (6.4 m). The locks pass an average of 10,000 ships per year, despite being closed during the winter from January through March, when ice shuts down shipping on the Great Lakes. The winter closure period is used to inspect and maintain the locks.
Canada Steamship Lines (CSL) is a shipping company with headquarters in Montreal, Quebec, Canada. The business has been operating for well over a century and a half.
Lake freighters, or lakers, are bulk carrier vessels that operate on the Great Lakes of North America. These vessels are traditionally called boats, although classified as ships.
The term Seawaymax refers to vessels which are the maximum size that can fit through the canal locks of the St. Lawrence Seaway, linking the inland Great Lakes of North America with the Atlantic Ocean.
Neebish Island is located in the U.S. state of Michigan, in the St. Marys River, which connects Lake Superior and Lake Huron at the easternmost point of Michigan's upper peninsula.
The Great Loop is a system of waterways that encompasses the eastern portion of the United States and part of Canada. It is made up of both natural and man-made waterways, including the Atlantic and Gulf Intracoastal Waterways, the Great Lakes, the Erie Canal, and the Mississippi and Tennessee-Tombigbee Waterway. The entire loop stretches about 6,000 miles (9,700 km).
The Round Island Channel is a navigable Lake Huron waterway located between Mackinac Island and Round Island in the Straits of Mackinac. It forms a key link in the lake freighter route between Lake Superior and Lake Michigan, on which millions of tons of taconite iron ore are shipped annually. The channel also provides access to the harbor of Mackinac Island, Michigan, and is used by commercial ferryboats delivering passengers to the small island city.
The Great Lakes megalopolis consists of a bi-national group of metropolitan areas in North America largely in the Great Lakes region. It extends from the Midwestern United States in the south and west to western Pennsylvania and Western New York in the east and northward through Southern Ontario into southwestern Quebec in Canada. It is the most populated and largest megalopolis in North America.
Montrealais was a lake freighter launched in 1961. Constructed in two parts, the vessel was completed in 1962 and registered in Canada. Utilized as a bulk carrier, the vessel served on the Great Lakes until 2015. Montrealais was sold three times between 1962 and 2012, when the freighter was acquired by Algoma Central Corp. and renamed Algoma Montrealais. The bulk carrier continued in service until 2015, when the vessel was renamed Mont and sold for scrap. Mont was taken to Aliağa, Turkey and broken up beginning on 10 July 2015.
Algoma Equinox is a lake freighter and lead ship of her class built for Algoma Central, a Canadian shipping company. The vessel was built to a new design by Nantong Mingde Heavy Industries at their shipyard in Tongzhou, China in 2013. The ship entered service in December 2013, operating in the Great Lakes and Saint Lawrence Seaway.
Manitou Passage is a navigable Lake Michigan waterway separating North and South Manitou Island from mainland Michigan. The passage—used by deep-draft lake freighters—is located in Leelanau County and is within the Manitou Passage Underwater Preserve.
Whitefish Bay is a self-unloading lake freighter that entered service with Canada Steamship Lines (CSL) in 2013. Built in China, the vessel is the third of CSL's Trillium-class ships. Her sister ships are Baie Comeau, Baie St. Paul and Thunder Bay. Whitefish Bay is used primarily to transport goods on the North American Great Lakes and the St. Lawrence Seaway.
