I'll make just two points, if I may, Mr. Chair, to correct a misperception I may have left with respect to the Fisheries Act.
If you make a regulation under the Fisheries Act, essentially that allows a level of discharge. That's the nature of the regulation-making power. Otherwise, it's prohibited. So in this case there's no point in making a regulation that would allow a discharge when a discharge is prohibited. I think everyone agrees that this is the preferred approach here.
With respect to water quantity, we do have 47 hydrometric stations that measure the water quantity in the region, and there is research that Dr. Wrona can describe that relates to the effect of water withdrawals on instream flow.
