The body of water featured here is Williston Lake, British Columbia, the largest lake, a man made lake, in British Columbia. This lake re-fills itself from falling snow and rain every 2 years. By contrast, Lake Superior, one of the Great Lakes, re-charges itself every 180 years and Lake Okanagan, in the dry region of south central British Columbia, has a re-charge period of 80 years. Williston Lake sits at an elevation of 2200 feet above sea level (671 m).

A properly constructed aqueduct would permit water to flow down hill to California without the aid of expensive energy consuming pumping stations.Ten feet of water, taken from the surface, every year, would provide approximately 4 million acre feet, annually, with minimal environmental impact in Canada. This is some of the purest, cleanest water in the world. If a fraction of the outflow of Williston Lake, 4 million acre feet, were diverted and sold in southern California for $1,000 per acre foot the annual revenue would be $4 billion.
