Opening of the spillway gates at Robert-Bourassa generating station

Описание к видео Opening of the spillway gates at Robert-Bourassa generating station

From October 11 to 14, 2018, a rare event took place at the Robert-Bourassa facility: the eight spillway gates were opened, one after the other, letting the water flow through at full capacity. These tests are part of Hydro-Québec’s dam safety program. Testing is performed every year, but the spillway gates are usually opened only to about 10%. This was the first time since 1987 that such a large flow was let through the gates.
