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.
