Funny you should mention the Winnipeg Aquaduct. I drive up and over it regularly as it's 4 miles south of my home. I say up and over because it is basically built on the ground not in it. It looks like a dyke and the water flows by gravity as Shoal Lake where the water is drawn from is 300 ft higher than Winnipeg and outside of the boundries of the Canadian Shield.

I agree about the employment rate on reserves but you need to train the people who use the equipment.
