We had a helicopter tour over the tar sands yesterday, which was really helpful. From that and from having read your presentations, something that really struck me and that I hadn't thought of before is the impact of the mining and the loss of streams. In one of your presentations, somebody showed us how, just over a four-year or five-year period recently, the streams that feed into the river are gone. I know from my work in the Wabamun area the impact of the mining on the lake regime and the water table.
I'm wondering whether that is being factored into these water models, not just climate change and so forth. Does this have any impact on the ecology and on the eventual water levels of the river?
