This photo of Manicouagan 5 Reservoir was taken from the road over the spillway. Even though it's the middle of June, there is still a bit of ice on the surface of the reservoir.

This photo of Manicouagan 5 Reservoir was taken from road crossing the top of the dam. The reservoir behind the dam has a surface area of about 1,973 sq km (761 sq miles). The length of shoreline of this reservoir is 1,322 km (821 miles) and the catchment area is 29,241 sq km (11,290 sq miles). The mean depth is 85 m (278 ft); the greatest depth is 350 m (1,148 ft) with a maximum seasonal fluctuation of 5.6 m (18.3 ft). It is the second largest lake in Quebec.

Another view of the Manicouagan 5 Reservoir taken from on top of the spillway. This is the lowest water line we had seen of this reservoir.

The Manicouagan 5 Reservoir taken approximately 70 KM (43 miles) north of the dam. This lake was probably made 212 million years ago when a large meteor hit the earth. When viewed from a satellite, this lake looks donut shaped and is the largest impact crater still preserved on the surface of the Earth. It is 70 km (43 miles) in diameter and is thought to originally have been 100 km (62 miles).
