The Saint Marys River ( US designation) (official name in Canada : English St. Marys River ; French Rivière Ste-Marie ) is a river that over its entire length the border between the US state of Michigan and that in southern Canada Province of Ontario forms.
Course and geography
The Saint Marys River forms the outflow of Lake Superior , the largest of the five Great Lakes in North America . The river leaves the lake at the end of Whitefish Bay and flows about 120 km in a south-easterly direction to Lake Huron at a gradient of almost 8 m.
Rapids (called Sault Sainte Marie in French ) lie on the Saint Marys River at the outflow from Lake Superior . Further downstream at the twin towns of Sault Ste. Marie (Ontario) and Sault Ste. Marie, Michigan is where the Soo Locks are located .
Major tributaries of the Saint Marys River on the Ontario side are the Garden River and the Bar River . Other Canadian tributaries include: Fort Creek, Root River , Little Carp River, Big Carp River, Lower Echo River, Desbarats River, and the Two Tree River. American tributaries are: Gogomain River, Munuscong River, Little Munuscong River, Waishkey River, and the Charlotte River.
In the river are the following islands: Drummond Island , St. Joseph Island , Whitefish Island , Sugar Island and Neebish Island .
history
Before the Europeans reached the Saint Marys River, the indigenous people used the river for fishing and trading. The French explorer Étienne Brûlé was the first European to explore the rapids around 1621. In 1641 the Jesuit priests Isaac Jogues and Charles Raymbault followed him and met the Ojibway there . They named the rapids Sault Ste. Marie ( sault means "rapids" in Old French ).
Fort St. Joseph was established on the Canadian bank in 1796 to protect the trading post and ensure British influence in the region. The fort served this purpose during the British-American War of 1812.
The first modern lock, known as the American Lock , was completed in May 1855 by Erastus Corning 's St. Mary's Falls Ship Canal Company . Today there are four parallel locks on the US side of the river, but only two of them are in permanent operation. The Soo Locks lock system became part of the Great Lakes Waterway system in 1959 .
Competitive pressure led to the fact that in 1895 a lock, the Canadian Lock on Sault Ste. Marie Canal , was built. Today this is only used by leisure boats.
bridges
The Sault Ste. Marie International Bridge , a truss arch bridge, directs road traffic across the river. To the west of it the Sault Ste. Marie International Railroad Bridge , a single track railway bridge, over the Saint Marys River.
