Too bad they won't let you embed this video. Looks like they are putting that $6.5 billion to good use already. These video's show the sections of the rivers that are going to be dammed. The Rupert one has a bridge that the pilot flies beneath.

Yes, a really big project that Hydro Quebec recently finished. Diverting the Rupert River into the Eastmain. Permanantly reducing the rivers flow by over 3/4's. Imagine what affect this is going to have on the ecosystem of the river. Check out these two videos to see what the Rupert was and isn't anymore.
