Lake Erie (/ˈɪri/; French: Lac Érié) is the fourth largest lake (by surface area) of the five Great Lakes in North America, and the tenth largest globally or twelfth largest globally if measured in terms of surface area. It is the southernmost, shallowest, and smallest by volume of the Great Lakes and therefore also has the shortest average water residence time. It is bounded by Ontario to the north, Ohio, Pennsylvania, and New York to the south, and Michigan to the west. The lake is named after the Erie tribe of Native Americans who lived along its southern shore. The outflow from the lake provides hydroelectric power to Canada and the U.S. as it spins huge turbines at Niagara Falls. The lake's environmental health has been an ongoing concern for decades, with issues such as overfishing, pollution and more recently algal blooms and eutrophication generating headlines.

The Great Lakes (sometimes, Laurentian Great Lakes) are a collection of freshwater lakes located in northeastern North America, on the Canada–United States border, which connect to the Atlantic Ocean through the Saint Lawrence Seaway and the Great Lakes Waterway. Consisting of Lakes Superior, Michigan, Huron, Erie, and Ontario, they form the largest group of freshwater lakes on Earth, containing 21% of the world's surface fresh water. The total surface is 94,250 square miles (244,106 km2), and the total volume (measured at the low water datum) is 5,439 cubic miles (22,671 3km). The lakes are sometimes referred to as the North Coast or "Third Coast" by some citizens of the United States. They have also been referred to as North America's fourth coast, as traversing the shoreline of each of the lakes covers about 17,000 km (11,000 mi) roughly the distance of almost half the Earth's equator.

The Great Lakes began to form at the end of the last glacial period around 10,000 years ago, as retreating ice sheets carved basins into the land and they became filled with meltwater. The lakes have been a major source of trade through their region, and are home to a large number of aquatic species. Many invasive species have been introduced due to trade in the area, and some threaten the region's biodiversity.

The Canada–United States border, officially known as the International Boundary, is the longest international border in the world shared between the same pair of countries. The terrestrial boundary (including small portions of maritime boundaries on the Atlantic, Pacific, and Arctic coasts, as well as the Great Lakes) is 8,891 kilometres (5,525 mi) long, including 2,475 kilometres (1,538 mi) shared with Alaska. It is Canada's only land border.

The current border originated with the Treaty of Paris in 1783, which ended the war between Great Britain and the separating colonies which would form the United States. The 45th parallel was established as the border between Lower Canada (Quebec) and New York State (including what is now Vermont). The St. Lawrence River and the Great Lakes became the boundary between Upper Canada and the United States.

The Erie Canal is a canal in New York that originally ran about 363 miles (584 km) from Albany, New York, on the Hudson River to Buffalo, New York, at Lake Erie, at the time completing a navigable water route from New York City and the Atlantic Ocean to the Great Lakes. The canal contains 36 locks and encompasses a total elevation differential of approximately 565 ft. (169 m), and is widely regarded a chief cause that New York eclipsed Philadelphia as the largest city and port on the Eastern Seaboard of the United States.

First proposed in 1807, it was under construction from 1817 to 1825 when it officially opened on October 26, 1825. In a time when bulk goods were limited to pack animals (an eighth-ton [250 pounds (113 kg)] maximum), and there were no steamships or railways, water was the most cost-effective way to ship bulk goods or significant tonnages of any kind going back to the earliest days of recorded history.

The Great Lakes Waterway is a system of channels and canals that makes all of the Great Lakes accessible to smaller oceangoing vessels on all of the lakes and to large ore and coal carriers upstream of the Niagara River (Lakes Erie, Huron, Michigan, and Superior). Its principal civil engineering works have been the Welland Canal, which bypassed Niagara Falls between Lake Ontario and Lake Erie, and the huge Soo Locks, which bypass the rapids of the St. Marys River between Lake Superior and Lake Huron, at Sault Sainte Marie, Michigan. Dredged channels cross the St. Clair River, Lake St. Clair, and Detroit River between Lake Huron and Lake Erie. See the article on Lake St. Clair. Usually, one or more U.S. Coast Guard icebreakers help keep the water passage open for part of the fall and winter, although shipping usually ceases for two to three months each winter.

The Great Lakes Waterway is supplemented by the Saint Lawrence Seaway, which makes the Saint Lawrence River navigable from Montreal to Kingston, Ontario.

The Saint Lawrence Seaway (French: la Voie Maritime du Saint-Laurent), is the common name for a system of locks, canals and channels that permits ocean-going vessels to travel from the Atlantic Ocean to the Great Lakes, 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. This section downstream of the Seaway is not a continuous canal, but rather it consists of several stretches of navigable channels within the river, a number of locks, as well as canals along the banks of the St. Lawrence River to bypass several rapids and dams along the way. A number of the locks are managed by the Canadian Saint Lawrence Seaway Management Corporation and others are managed by the American Saint Lawrence Seaway Development Corporation.

Erie /ˈɪəri/ is a city located in northwestern Pennsylvania in the United States. Named for the lake and the Native American tribe that resided along its southern shore, Erie is the state's fourth-largest city (after Philadelphia, Pittsburgh and Allentown), with a population of 102,000. Erie's Metropolitan Area consists of approximately 280,000 residents and an Urbanized Area population of approximately 195,000. The city is the seat of government for Erie County. Erie is the principal city of the Erie, PA Metropolitan Statistical Area.

Erie is near Buffalo, New York, Cleveland, Ohio, and Pittsburgh, Pennsylvania. Once teeming with heavy industry, Erie's manufacturing sector remains prominent in the local economy, though service industries, healthcare, higher education, and tourism are emerging as greater economic drivers. Millions visit Erie for recreation at Presque Isle State Park, as well as attractions like casino and horse racetrack named for the state park.

Lake Erie

The Western Basin of Lake Erie is the shallow flat basin that comprises the western third of the lake. Even with average depths of less than 25 feet, this part of the lake contains world famous walleye fishing grounds with numerous charter fishing boats operating out of the U.S. states of Michigan and Ohio and the Canadian province of Ontario.
