Lake Timiskaming or Lake Temiskaming (French : Lac Témiscamingue) is a large freshwater lake on the provincial boundary between Ontario and Quebec, Canada. The lake, which forms part of the Ottawa River, is 110 kilometres (68 mi) in length and covers an area of almost 295 km2 (114 sq mi). Its water level ranges between 175 m (574 ft) and 179 m (587 ft) above sea-level, with a mean annual average of 178.4 m (585 ft). [1] The lake is in places up to 216 m (709 ft) deep. There are several islands on the lake, notably Mann and du Collège Islands.

The name is from the Algonquin Temikami or Temikaming, meaning "deep body of water with rapid winds”

There are 30 species of fish in Lake Timiskaming, the best known are northern pike, sturgeon, lake trout, walleye, smallmouth bass, bullhead, carp, burbot, perch, and whitefish.

The lake was shaped during the last ice age when glaciers carved into the rock. It is also the remnants of a huge basin called Lake Ojibway, which existed about 9,500 years ago. Between 1976 and 1981 the DuPagne Classic fishing tourney took place at Wells Rock (David's tobogganing hill).[ citation needed ]

Timiskaming Graben

Lake Timiskaming is located within an ancient major rift valley that extends several hundred miles to the north-east called the Timiskaming Graben. It is the northern extension of the Ottawa-Bonnechere Graben, which is part of the Saint Lawrence rift system. There have been recent earthquakes along the rift valley, the most recent being in 2000. There are numerous faults in the area and has produced cliffs such as Devil's Rock, just 5 km (3 mi) south of Haileybury and is dated to be 2.2 billion years old. There are known kimberlite pipes within the rift valley that are considered to be diamondiferous. [2]

Ottawa River River in Canada

The Ottawa River is a river in the Canadian provinces of Ontario and Quebec. It is named in honour of the Algonquin word 'to trade', as it was the major trade route of Eastern Canada at the time. For most of its length, it defines the border between these two provinces. It is a major tributary of the St. Lawrence River and the longest river in Quebec.

Temiskaming Shores City in Ontario, Canada

Temiskaming Shores is a city in the Timiskaming District in Northeastern Ontario, Canada. It was created by the amalgamation of the town of New Liskeard, the town of Haileybury, and the township of Dymond in 2004. The city had a total population of 9,920 in the Canada 2016 Census. Temiskaming Shores is Ontario's second-smallest city, in terms of population, after Dryden. Haileybury is the seat of Timiskaming District.

Lake Nipissing

Lake Nipissing is a lake in the Canadian province of Ontario. It has a surface area of 873.3 km2 (337.2 sq mi), a mean elevation of 196 m (643 ft) above sea level, and is located between the Ottawa River and Georgian Bay. Lake Nipissing is the third-largest lake entirely in Ontario. It is relatively shallow for a large lake, with an average depth of only 4.5 m (15 ft). The shallowness of the lake makes for many sandbars along the lake's irregular shoreline. The lake reaches a maximum depth of 64 m (210 ft) near the mouth of the French River, off the shore of Blueberry Island. The lake has many islands most of which are protected under the Protection of Significant Wetlands scheme, controlled by the Ministry of Natural Resources and Forestry.

Mattawa River

The Mattawa River is a river in central Ontario, Canada. It flows east from Trout Lake east of North Bay and enters the Ottawa River at the town of Mattawa. Counting from the head of Trout Lake, it is 76 km in length. The river's name comes from the Algonquin word for "meeting of waterways".

Eastern Ontario Secondary region in Ontario, Canada

Eastern Ontario is a secondary region of Southern Ontario in the Canadian province of Ontario which lies in a wedge-shaped area between the Ottawa River and St. Lawrence River. It shares water boundaries with Quebec to the north and New York State to the east and south, as well as a small land boundary with the Vaudreuil-Soulanges region of Quebec to the east.

Devils Rock

Devil's Rock is a granite escarpment located 5 kilometres (3 mi) south of Temiskaming Shores, Ontario, Canada. The cliffs rise 300 feet (91 m) above Lake Timiskaming and extend nearly as far underwater as they do above, giving Devil's Rock a cliff face roughly 600 feet (180 m) tall.

Volcanism of Canada Volcanic activity in Canada

Volcanic activity is a major part of the geology of Canada and is characterized by many types of volcanic landform, including lava flows, volcanic plateaus, lava domes, cinder cones, stratovolcanoes, shield volcanoes, submarine volcanoes, calderas, diatremes, and maars, along with less common volcanic forms such as tuyas and subglacial mounds.

Ottawa-Bonnechere Graben Rift valley extending from near Montréal through Ottawa in Canada

The Ottawa-Bonnechere Graben is a geological structure that coincides with a 55 km (34 mi) wide topographic depression extending from near Montréal through Ottawa. It is part of the Saint Lawrence rift system that also includes the seismically active Saguenay graben. This rift valley was formed when the Earth's crust moved downward about a kilometre between two major fault zones known as the Mattawa and Petawawa faults.

Timiskaming Graben Northwesterly extension of the Ottawa-Bonnechere Graben

The Timiskaming Graben is a 400 km (250 mi) long and 50 km (31 mi) wide depression straddling the Ontario–Quebec border in Eastern Canada. It is a northwesterly extension of the Ottawa-Bonnechere Graben, a failed arm of the Saint Lawrence rift system which is related to the opening of the Iapetus Ocean.

1935 Timiskaming earthquake

The 1935 Temiskamingue earthquake occurred on November 1 with a moment magnitude of 6.1 and a maximum Mercalli intensity of VII. The event took place in the Western Quebec Seismic Zone in the Abitibi-Témiscamingue region of Quebec.

Volcanism of Eastern Canada

The volcanology of Eastern Canada includes the hundreds of volcanic areas and extensive lava formations in Eastern Canada. The region's different volcano and lava types originate from different tectonic settings and types of volcanic eruptions, ranging from passive lava eruptions to violent explosive eruptions. Eastern Canada has very large volumes of magmatic rock called large igneous provinces. They are represented by deep-level plumbing systems consisting of giant dike swarms, sill provinces and layered intrusions. The most capable large igneous provinces in Eastern Canada are Archean age greenstone belts containing a rare volcanic rock called komatiite.

Gregory Rift

The Gregory Rift is the eastern branch of the East African Rift fracture system. The rift is being caused by the separation of the Somali plate from the Nubian plate, driven by a thermal plume. Although the term is sometimes used in the narrow sense of the Kenyan Rift, the larger definition of the Gregory Rift is the set of faults and grabens extending southward from the Gulf of Aden through Ethiopia and Kenya into Northern Tanzania, passing over the local uplifts of the Ethiopian and Kenyan domes. Ancient fossils of early hominins, the ancestors of humans, have been found in the southern part of the Gregory Rift.

Canadian Arctic Rift System North American geological structure

The Canadian Arctic Rift System is a major North American geological structure extending from the Labrador Sea in the southeast through Davis Strait, Baffin Bay and the Arctic Archipelago in the northwest. It consists of a series of interconnected rifts that formed during the Paleozoic, Mesozoic and Cenozoic eras. Extensional stresses along the entire length of the rift system have resulted in a variety of tectonic features, including grabens, half-grabens, basins and faults.
