Description
The Crater & Dam...Le Cratère & Le Barrage
Manicouagan Reservoir (also Lake Manicouagan) is an annular lake in central Quebec, Canada. The lake covers an area of 1,942 km², and its eastern shore is accessible via Route 389. The island in the centre of the lake is known as René-Levasseur Island, and its highest point is Mount Babel. The lake and island are clearly seen from space and are sometimes called the "eye of Quebec." In 2007, the Manicouagan lake was astronaut Marc Garneau's nomination for the CBC's Seven Wonders of Canada competition.
Manicouagan Reservoir lies within the remnant of an ancient eroded impact crater (astrobleme). The crater was formed following the impact of a 5 kilometres (3 miles) diameter asteroid which excavated a crater originally about 100 km (62 mi) wide although erosion and deposition of sediments have since reduced the visible diameter to about 72 km (45 mi). It is the fifth largest impact crater known on earth. Mount Babel is interpreted as the central peak of the crater.
Recent research has shown that impact melt within the crater has an age of 214 ± 1 million years. As this is 12 ± 2 million years before the end of the Triassic, the impact that produced the crater cannot have been the cause of the Triassic-Jurassic extinction event.

Le réservoir Manicouagan aussi appelé lac Manicouagan est un cratère météoritique qui a été inondé par l’édification du barrage Daniel-Johnson sur la rivière Manicouagan (Côte-Nord du Québec). D’une superficie de 2 000 km2 et d’une profondeur moyenne de 73 mètres, le réservoir Manicougan est un des plus gros réservoirs du monde en volume et en profondeur. Le réservoir alimente les centrales hydroélectriques de Manic 5 et Manic 5-PA.
Le cratère aurait été formé suivant l'impact d'un astéroïde d'environ 5 km de diamètre. Le diamètre original du cratère est évalué à 100 km, mais suite à l'érosion et au dépôt de sédiments, sa taille apparente aujourd'hui est réduite à 72 km. Parmi les cratères d'impact reconnus scientifiquement, il s'agit actuellement du 5e plus grand répertorié sur Terre. le Mont Babel au centre du réservoir est interprété comme le vestige du pic central du cratère.
L'âge estimé de l'impact est de 214 ± 1 millions d’années, donc durant le Trias. Précédant de 12 millions d'années l'extinction du Trias-Jurassique, l'impact de la Manicouagan ne peut être la cause de cette catastrophe.
