The La Grande series of hydro dams and associated underground power houses in the James Bay area of Quebec are among the largest in the world. It was enjoyable for me to have been able to visit this remote part of Canada and to observe the facilities. This photo shows the huge 'stair-step' spillway for the dams near Radisson, used to bypass water around the generating station when the flow is more than the turbines can use. It is difficult to grasp the scale of this rock-cut, but those green areas are trees similar to those in the foreground.
While we were a bit further north on our fishing trip (see Off the Beaten Path), there were opportunities to observe the general landscape. As you can see, there are patches of lichen/moss, rocks and huge areas of relatively short evergreen trees.
Free guided visit, open everery day, you should reserve one day in advance, bring one
identification with picture.
The hydropower, the largest in the world is situated at 137 meters Under the lake level.

Hydroelectric powerplant on the La Grande river. To visit, contact the Hydro-Québec office in Radisson.
When going there, make it a daytrip and visit the Cree village of Chisasibi a bit further west too.
The largest underground hydro-electric power plant in the world. The turbine hall is the size of a cathedral. Well worth the visit. Go to the Hydro-Québec office downtown, visits are organised every day.
Also see the main open-air landmark of Radisson: the overflow evacuator, nicknamed "The Staircase of the Giants".
This park is dedicated to the memory of the pioneers who built the hydroelectric power plants.
To visit, go to the souvenir shop at 65 Desgroseillers in downtown Radisson, the very friendly people there will help you further.
