I have a couple of quick comments. My concern, after visiting the Fort Chipewyan first nations group and visiting Lake Athabasca, deals with the lowering of the lake level.
Mr. Maas, you talked quite a bit in your presentation about, obviously, the UNESCO heritage site, Wood Buffalo National Park. You talked about flow disruptions. You were very critical of flow disruptions caused by drawings on the Athabasca River for oil sands operations, particularly during low flows and peak flows.
When I flew over the oil sands, I saw several ponds that had the nice green that almost looks like a mountain lake. So I'm assuming that those ponds were water that was drawn from the river and kept in storage—pre-processing, quite distinctively different from the tailings ponds, which is unmistakable.
My question is going to focus on the other aspect. What I heard from the testimony and the questions I've asked is that the major cause of loss of water is due to the flow disruption of the Peace River, which is substantially larger than the Athabasca River. Can you provide our committee any historical information as to what those flow rates are? How big is the Athabasca relative to the Peace?
