The Great Recycling and Northern Development (GRAND) Canal of North America or GCNA is a water management proposal designed by Newfoundland engineer Thomas Kierans to alleviate North American freshwater shortage problems. It proposed damming James Bay, using the techniques of the Zuiderzee/IJsselmeer, to prevent its waters mixing with the salt water of Hudson Bay to the north. This would produce an enormous freshwater lake, some of which would be pumped south into Georgian Bay where it would increase the freshwater levels of the lower Great Lakes. The flow would be roughly equivalent to "2.5 Niagara Falls."
