There's one other comment that struck me when we flew over Kearl Lake. You mentioned that it's a shallow lake that freezes right through and that the compensation lakes you'll be making are deeper. Certainly on the surface, I thought that seemed to make sense, although subsequent commentary from some of our native elders and chiefs was that it might not necessarily be a good thing.
My concern is that the lakes to be reclaimed are deeper because they were created through mining processes. Have there been a lot of studies done on what kinds of habitat the reclaimed lakes will create in the long term? I guess I'll turn to Mr. Duane afterwards, as he has an extensive slide on this.
