Yes, I need to catch up on the numbers, but as I understand it there are two critical drivers, and the dam is one of them. There's also the impact of climate change on that river as well, in fact, on the Peace-Athabasca Delta itself. It is a net loss of water from the Peace-Athabasca Delta, so it loses more water than it gets because of evaporation, actually. There are a whole range of complex factors, human-induced as well as natural, at play in that area.
