Historically, the rivers are at a 10-year low right now from the last time I got an update from our staff. The one thing that MTS did this year was factor in the possibility of that. The way we operated this year is we adjusted our loads for shallower draft. The low-water levels on the Mackenzie River haven't hampered our schedule. The other nice thing was, I have talked about it in this House, with the Steam River bridge that was on fire and the fuel company picked up the slack and delivered the fuel to Hay River by truck. It actually got there earlier than anticipated, so that helped assist with the schedule.
