Situated in eastern CANADA in Quebec (Québec) province's Côte-Nord region, Lake Manicouagan or Manicouagan Reservoir (Réservoir Manicouagan in French) is an artificial lake shaped like a ring of fire! Speaking of fire, this area maybe experienced some fire action when a meteorite struck eastern Quebec over 200 million years ago, forming the circular impact which eventually allowed water to collect. The Manicouagan crater boasts a designation of being the world's sixth-largest crater! How and when was the reservoir formed? Lake Manicouagan was created by Daniel-Johnson Dam, which was completed in 1968 and dammed up the southward-flowing Manicouagan River. This river reaches the wider Saint Lawrence river and Gulf of Saint Lawrence near the city of Baie-Comeau. The Earth likely has other ring-shaped (annular) lakes, but these are not as large and remarkable compared to mighty Lake Manicouagan! Finally, Lake Manicouagan's large island is Île René-Levasseur, which will be featured in the next post.
