The deepest one, I believe, is equivalent to the water level on Lake Athabasca, but because of the fluctuation of the water levels in the past year we have run into some difficulties.
I am surprised about the question that was asked here about the water system. We have experienced difficulties with our pumps running out of water, and I believe that was related to the water entering in from the Peace River into Lake Athabasca that had fluctuated the water levels and created some problems for us.
