Mackenzie River
At , the Mackenzie River drainage basin encompasses nearly 20 percent of Canada. About , or 54 percent of the basin, lies above Great Slave Lake. Permafrost underlies about three-quarters of the watershed, reaching up to deep in the Mackenzie Delta. As a whole, the Mackenzie basin receives only meager to moderate rainfall, averaging over the entire basin, though mountain areas experience much higher precipitation, and areas near and north of the Arctic Circle receive much lower precipitation.
Great Recycling and Northern Development Canal
In his GCNA proposal, Kierans asserts that experience in the Netherlands demonstrates that a large new freshwater source can be created in Canada's James Bay by collecting runoff from many adjacent river basins in a sea level, outflow-only dyke-enclosure. The project would capture and make available for recycling the entire outflows of the La Grande, Eastmain, Rupert, Broadback, Nottaway, Harricana, Moose, Albany, Kapiskau, Attawapiskat and Ekwan rivers.
Moreover, Kierans claims that the California Aqueduct proves that runoff to James Bay can be beneficially recycled long distances and over high elevations via the GRAND Canal. The GCNA would stabilize water levels in the Great Lakes and St. Lawrence River and improve water quality. The GRAND Canal system would also deliver new fresh water from the James Bay dyke-enclosure, via the Great Lakes, to many water deficit areas in Canada and the United States. The project was estimated in 1994 to cost C$100 billion to build and a further C$1 billion annually to operate, involving a string of nuclear reactors and hydroelectric dams to pump water uphill and into other water basins.
