The Thames River /tɛmz/[5] is located in southwestern Ontario, Canada.

The Thames flows southwest for 273 kilometres (170 mi)

Lake St. Clair. Its drainage basin is 5,825 square kilometres (2,249 sq mi).[3]

The river is also known as Deshkaan-ziibi / Eshkani-ziibi ("Antler River") in the

Lieutenant Governor John Graves Simcoe named the river after the River Thames in England.[6]
Early French Canadians referred to it as La Tranche, for the wide and muddy waters of its lower section.

Much of the Thames was formerly surrounded by

Carolinian forests, but much of this forest has been cleared to permit agriculture and other forms of development
.

Two

conservation authorities together have jurisdiction over the Thames River watershed, the Upper Thames River Conservation Authority
and Lower Thames Valley Conservation Authority, and work to prevent damaging floods and undertake other resource management activities.

There are three rivers in the watershed with Thames in the name—the Thames River itself, North Thames River, and Middle Thames River. These are also known locally as South Branch, North Branch, and Middle Branch. The South Branch, which begins as several field drains near Tavistock and initially flows southeasterly before turning southwesterly towards Woodstock, is the main stem Thames River and officially carries the Thames River name.[7][8]

The Thames River and North Thames River in the upper part of the watershed flow through valleys created during the retreat of the

Oneida First Nations settlements. Tributaries of the three Thames Rivers include the Avon River
, Dingman Creek, Jeanettes Creek, McGregor Creek, Medway Creek, Pottersburg Creek, Stoney Creek, Trout Creek and Waubuno Creek.

Three separate dams are used to control seasonal flooding in the watershed: Wildwood Dam, located on Trout Creek which flows into the North Thames River; Pittock Dam, located on the Thames River near Woodstock; and Fanshawe Dam located on the North Thames River in the northeasterly area of London. A fourth dam at Springbank Park, downstream from the Forks, controlled water levels in central London from the 1870s until 2005 when it was closed for rehabilitation. One of the Springbank Dam's gates failed in 2008, causing the dam to be locked in the open position, and rehabilitation was delayed pending litigation between an engineering firm and the City of London.[9] On January 9, 2018, London's civic works committee voted to decommission the Springbank Dam permanently.[10]

History

The river was the location of an important battle of the War of 1812. The Battle of the Thames (also known as the Battle of Youwas) fought on October 5, 1813, between American General William Henry Harrison and British General Henry Proctor, along with Proctor's ally Tecumseh. Chief Tecumseh was killed in the battle.

In the final decades of the 19th century, pleasure boats began to operate on the Thames in

Byron
.

On May 25, 1881, the 'Victoria' capsized and sank in the Thames near what is today Greenway Park in London, killing 182 passengers. After the disaster all ferries could only carry their maximum capacity, and the popularity of boating on the Thames dropped considerably.

In the early morning hours of July 11, 1883, heavy rainfall caused considerable flooding on the Thames, especially in London. The "Princess Louise", which had been laid up, was forced over Waterworks Dam and capsized, killing 7, while the 'Forest City' was cast out into the river and partially damaged. This flood would be the first of two significant floods to strike the city.

On August 25, 1899, the "Thames" was set on fire and scuttled only feet from Waterworks Dam.

On April 27, 1937, the Thames River reached an all-time high of 21.5 feet (6.6 m) above normal flow resulting in 5 deaths and over 1000 homes being damaged.[11]

On August 13, 1950, a launch capsized and sank in London and killed four passengers.

On August 14, 2000, the Thames River was designated a Canadian Heritage River.

During the weekend of February 24–25, 2018, abnormally persistent rains caused significant flooding along the banks of the river. Extensive property damage was observed in

Chatham
and nearby Thamesville.
