First of all, on the Athabasca River, I didn't say that 66% was being used. I said that government policy—this is Alberta—is to allocate up to 66% of the Athabasca River flows or sources to the oil sands development. I was making a comparison between 37% of all fresh water sources in Alberta being allocated for oil and gas development in general. I was saying that the Athabasca River is a huge amount of that; it is allocated up to that amount. That doesn't say it's all being used now--of course not; that's over a long period of time. I'm just saying that's the way I was using that figure.
As for the figures with regard to the barrels of water for barrels of oil, 4.5 is the average that the Pembina Institute had worked out. Other institutes have worked out--these are independent of the industry and independent of government--as high as seven, so that's why they range between 4.5 and seven.
Mr. Carter says they have it down to two barrels of water per barrel of oil, or something to that effect. I'm assuming that's for 2006.
