The Manicouagan Reservoir is thought to be the result of the impact of a meteor 5 kilometres in diameter which produced the ring-shaped lake. Lac Manicouagan covers an area of 1,942 km², in the center of the lake is René- Lavasseur Island. The lake and the island can be seen clearly from space and is often called the “eye of Quebec.” The Manicouagan crater is one of the oldest known impact craters and is the largest visible impact crater on Earth. The Manicouagan reservoir is the fifth largest in the world in volume and can be used  for hydro-electric power production. Canadian astronaut Marc Garneau nominated the reservoir for the CBC’s Seven Wonders of Canada competition in 2007
