The Saint John River is a river, approximately 418 mi (673 km) long, located in the U.S. state of Maine and the Canadian province of New Brunswick. It forms part of the Canada-US border in two places along its length. The river drains an area of approximately 55,000 km², of which slightly more than half is located in New Brunswick. The Saint John is also the second longest river on North America's Atlantic coastline (between the St. Lawrence River and the Mississippi River). Only the Susquehanna is longer. The lower section of the River from Fredericton to Saint John is nicknamed the Rhine of North America, in reference to its popularity for recreational boating.

[edit] Description
The Saint John rises in Somerset County in northwestern Maine and flows northeast through western Aroostook County for a distance. Near Allagash, it is joined by the Allagash River. The portion of the Saint John River that lies entirely in Maine is essentially a wilderness waterway. Below St. Francis, the Saint John begins to form part of the International Boundary between Maine and New Brunswick.
Continuing its northeast course, the river passes Fort Kent, Maine, and then flows between Edmundston, New Brunswick and Madawaska, Maine, where it turns southeast, then passes between Van Buren, Maine and St. Leonard, New Brunswick. Near Grand Falls, New Brunswick the river enters entirely into New Brunswick, and changes direction to flow due south through the fertile Upper St. John River Valley, framed by the rising hills of the Appalachian range in Victoria and Carleton counties. At Perth-Andover, the river is joined by the Aroostook and the Tobique rivers. At Hartland it is crossed by the longest covered bridge in the world.
Further south at Woodstock the river leaves the Upper Valley and turns southeast away from the border region, eventually passing through New Brunswick's capital city Fredericton (where it becomes navigable), and the military town of Oromocto. Turning south from Oromocto, the river is joined by the short Jemseg River which empties New Brunswick's largest lake, Grand Lake. South of Fredericton the river becomes broad and shallow and it meanders through many low islands used for pastureland during dry periods in summer and fall.
South of the Jemseg, the Saint John River is surrounded by the low hills of the St. Croix Highlands - another component of the Appalachian range and it is joined by several lateral bays, including Belleisle Bay and the Kennebecasis River. The St. John River meets the Bay of Fundy at the industrial city of Saint John. At the river's mouth, there is a unique phenomenon caused by the high tides of the Bay. These tides are the highest in the world and cause the river to reverse its flow twice a day in a narrow gorge in the city's centre, called the Reversing Falls Rapids.
[edit] History
Members of the Maliseet Nation have historically called the river "Wolastoq", meaning "good and beautiful river". In 1604, parts of the lower river were explored by Samuel de Champlain and Sieur de Monts. Champlain named the river after John the Baptist because he reached the river's mouth on the saint's feast day, June 24.
The river valley formed an important part of the French colony of Acadia. Acadian settlements developed along the lower river during the 17th and 18th centuries; including Fort la Tour (Saint John) and Fort Anne (Fredericton). The area fell under English control during the Seven Years' War, after the English capture of Fort Anne in 1759. In 1784, many loyalist refugees from the Revolutionary War settled in Saint John. The new English colony of New Brunswick was created shortly afterwards and Fredericton was named the capital. English settlement of the fertile Upper River Valley would not occur until the early to mid 19th century. A Danish community (New Denmark) was established in the late 1800's. Meanwhile, francophone Quebecers settled the Madawaska region, also during the 19th century, travelling southwards along traditional portage routes. The Madawaska section of the river valley remains heavily francophone even today.
The river was an important trade route for the French, English and First Nations traders throughout the 17th and 18th centuries. The tremendous flow rate of the river and its tributaries during the spring freshet aided the development of the timber industry in western New Brunswick as the river became a conduit for log drives to saw and pulp mills in the south.
It is this same spring freshet which can proved disastrous to property owners along portions of the river, particularly when ice jams can cause extensive flooding during the spring break-up.
The Saint John River has been of tremendous importance to the development of western New Brunswick because it served as a transportation artery, particularly prior to the era of rail transport when paddle wheelers plied its waterways.
During the 1950s and 1960s, the river became a major source of hydroelectric power with the construction of dams at Beechwood and Mactaquac where large reservoirs have been created by damming its flow. These massive projects followed the construction of a smaller dam at Grand Falls, in 1925,where the river descends in a steep cataract. A consequence of the latter two dams has been a severe decline in migrating Atlantic Salmon, and the flooding of some valuable farmland to create the headponds.
In recent years, the river has seen a rise in recreational boating and ecotourism. The rich soil of the Upper St. John River Valley in Aroostook, Carleton, and Victoria counties is also an important area for the cultivation of potatoes.
[edit] Water Flow
The United States government maintains three gages on the river to measure water flow. The first is located in an unnamed township at () where the rivershed is 1,341 square miles, the second at Dickey, Maine () where the rivershed is 2,680 square miles, the third is maintained under agreement with Canada on the Canadian bank in Clair, New Brunswick at () where the rivershed is 5,665 square miles. At the most upstream gage the riverflow has ranged from 44,400 cubic feet per second to 59 cubic feet per second. At the Dickey gage flow has ranged from 91,700 cubic feet per second to 129 cubic feet per second. At the Clair gage flow has ranged from 151,000 cubic feet per second to 510 cubic feet per second. Water flow is highest during spring snowmelt and lowest in the fall. In early spring, upper sections of the river can experience ice-dam caused flooding, [1] while in the lower sections, flooding may occur during late spring from the shear volume of water which must make it's way through the narrow gorge at Reversing Falls.
