Chaudiere River basin

The Chaudière River (French for "Cauldron" or "Boiler") is a 185 kilometres (115 mi) long river with its source near the Town of Lac-Mégantic, in southeast Quebec, Canada. From its source Lake Megantic in the Estrie region, it runs northwards to flow into the St. Lawrence River opposite Quebec City.

Geography

The river's drainage area is 6682 square kilometres, initially in the Appalachian Mountains, then in the low-lands of the St. Lawrence, and include 236 lakes covering 62 square kilometres and approximately 180,000 inhabitants. Its annual medium flow at the station of Saint-Lambert-de-Lauzon is 114 m³/s, varying from 11 m³/s (low water) to 470 m³/s (spring high water), with historical maximum of 1760 m³/s.

Its principal tributaries are:

  • Rivière du Loup (not to be confused with Rivière du Loup in the Bas-Saint-Laurent), also known as the Rivière Linière
  • Famine River
  • Beaurivage River
  • Saint-Victor River

The river's basin has nearly 50% of the faunal richness of Quebec, namely 330 out of 653 vertebrate species known in the province can be found here.

The river, and the 40 metres (130 ft) high Chaudière Falls which it passes over en route, are popular outdoor recreation areas.

History

The Abenaki indigenous people resided close to the Chaudière Falls and named it “Kikonteku”, meaning “River of the Fields”. On the charts of Samuel de Champlain, it was given the name “Etchemin River” (a name now used for another river whose drainage area borders with that of the Chaudière River). It was called "Rivière du Sault de la Chaudière" for a period of time before it became simply "Rivière Chaudière" towards the end of the 18th century. This name refers to the waterfall close to its mouth.

Its location was strategic for French colonization during the 18th century because the river was a natural link between New France and the British colonies to the south. It was also used by Benedict Arnold at the time of his 1775 expedition in the invasion of Quebec.

In 1823, gold was found along its shores in the Eastern Townships of Quebec.1

On 6 July 2013 the Lac-Mégantic derailment caused a major oil spill which contaminated the river at its source at Lac Mégantic.2 Downstream communities such as Saint-Georges (80 kilometres (50 mi) to the northeast) were forced to obtain potable water from alternate sources and residents asked to limit their water consumption.3 Floating barriers were installed in an attempt to contain the contamination.

The river today

The Chaudière valley mostly crosses the Beauce area. The river impacts its industries and way of life, particularly during spring run-off, when it frequently overflows into populated areas, in spite of the 160 dams and levees. The river flows through several cities and villages of the area such as Sainte-Marie, Saint-Georges, Beauceville, and Saint-Joseph-de-Beauce.

The river is a popular location for outdoor sports, particularly at Lac-Mégantic and at Parc des Chutes-de-la-Chaudière. Located close to the mouth of the river at Lévis, this park offers cycling and hiking trails, as well as a footbridge suspended above the river which offers a view of the waterfalls.

The falls have been harnessed for hydro-electric power since the beginning of the 20th century. The dam was rebuilt in 1999 on the remains of the old installations, and now consists of a small 24 MW power station.
