5 Because water withdrawn for use in hydroelectric facilities is immediately returned to its source, withdrawal figures used in this report do not include withdrawals for hydroelectric purposes.

6 The interim report data were current from 1978 to 1987 for Michigan and 1992 for Ontario.

8 The Great Lakes Commission has provided the Commission with more recent data from Illinois (1994), Indiana (1995), Michigan (multiyear back to 1978), Minnesota (1998), New York (1995), Ohio (1998), Pennsylvania (1994), Wisconsin (1994), and Quebec (1994). Ontario=s data remain current to 1992.

11 The state of Michigan believes that a consumptive use rate of approximately 90 percent is a more realistic figure. The 1995 USGS data indicate that the irrigation consumption in the U.S. portion of the Great Lakes Basin is 94 percent.

12 See Section 6 for further information on groundwater. The Commission was not provided with groundwater use data for the Canadian section of the Basin.

14 In 1905, Missouri filed suit in the U.S. Supreme Court to force Illinois to end the diversion. The Court ruled for Illinois. The Supreme Court first began to limit the Chicago Diversion in 1925 (Stanley A. Changnon and Mary E. Harper, "History of the Chicago Diversion," in The Lake Michigan Diversion at Chicago and Urban Drought, edited by Stanley A. Changnon, NOAA Contract 50WCNR306047, Mahomet, Illinois, 1994, pp. 16B38).

17 In terms of volume, the Welland Canal, with an average diversion of 261 cms (9,200 cfs) is the largest intrabasin diversion in the Great Lakes Basin. Welland has been estimated to lower the mean levels of Lake Erie by 13.4 cm (5 in.), of Lakes MichiganBHuron by 5.5 cm (2 in.), and of Lake Superior by 1.8 cm (1 in.).

18 A major impetus for this study was public concern over an application from a firm called NOVA to export water via ship from Lake Superior. At a public hearing, a NOVA representative told the Commission that NOVA had neither conducted a feasibility analysis nor identified any customers for Lake Superior water at the time it sought and obtained a permit from Ontario for the bulk removal of water. Ontario later revoked the permit.

28 According to a recent study conducted by the U.S. Conference of Mayors, 4 of every 10 cities are considering some form of privatization in hopes of reducing costs and encouraging private capital investment.

29 La Compagnie Suez Lyonnaise des Eaux, a private French company, manages and operates, in varying degrees, water utilities through contractual arrangements made with municipalities, cities, and communities all over the world. They pride themselves on improved technology, improved water quality, and improved customer service while making profits. For example, one year after Lyonnaise signed the contract in Casablanca, satisfied customer approval rating increased to 80 percent, and 1,000 km of wastewater mains were scoured. Also, in the United Kingdom, Thames Water International has invested more than $1.6 billion U.S. on infrastructure. Among the improvements was the installation of new technology that detects leaks. The water that the company loses to leakage each year has declined by 31 percent since 1996.

30 British water utilities were entirely privatized in 1989. Since then, some private firms in control of water utilities in England and Wales have been convicted of pollution violations. Regulation in the water services industry is extremely inefficient, in part because the Natural Rivers Authority has to work through numerous agencies. (Some publicly owned and operated utilities in North America have also been convicted of pollution violations).

42 Even if water levels do not change significantly, a warming of the Lakes could significantly change the structure of the fish population, with the number of cool- and warm-water fish gradually rising and the number of cold-water fish declining. In addition, warmer climate could reduce the frequency of water-column turnovers, a development that would adversely impact fish species and their habitats by altering nutrient and dissolved oxygen distributions.
