RE: E-M:/Granholm Puts Moratorium on Great Lakes Water

Rane Curl's comments on the amount of Great Lakes' water available as "supply" are well taken. I have read the figure 1% as the amount of Lake Michigan water draining from the lake yearly. An alternative statement would be that it would take about a century to replace the water presently in the lake. Even that 1% could not be consumed/diverted without major impact since it, along with comparable discharges from the other Great Lakes, constitute the flows of the St. Mary, Detroit, Niagara, and St. Lawrence Rivers which are themselves "water supplies" for many hundreds of miles of habitat and adjacent human habitation. While the Great Lakes constitute an awesome natural resource as such, the amount of water "available" for taking without dire consequences is no more than that available in any area with comparable rainfall.
