Canal this trend. Yet in other countries canals grew in size as construction techniques improved. During the 19th century in the US, the length of canals grew from to over 4,000, with a complex network making the Great Lakes navigable, in conjunction with Canada, although some canals were later drained and used as railroad rights-of-way. In the United States, navigable canals reached into isolated areas and brought them in touch with the world beyond. By 1825 the Erie Canal, long with 36 locks, opened up a connection from the populated Northeast to the Great Lakes. Settlers flooded into regions serviced by
Great Recycling and Northern Development 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. Kierans argues recycling runoff from a dike-enclosure in Canada's James Bay is not harmful
