Manicouagan Reservoi, Canada

Sept-Rivieres –Caniapiscau – Manicouagan Reservoir lies in Eastern Quebec 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 confirmed impact crater known on earth. Mount Babel is interpreted as the central peak of the crater, formed by post-impact uplift.
The lake was enlarged by flooding from the massive Manicouagan or Manic (Manic 1, Manic 2…) series of hydroelectric projects undertaken by Hydro-Québec, the provincial electrical utility, during the 1960s. The complex of dams is also called the Manic-Outardes project because the rivers involved are the Manicouagan and the Outardes. (SOURCE: wikipedia.org)
