As previously reported here, the Great Lakes and St. Lawrence Cities Initiative (the Cities Initiative) requested a hearing before the Great Lakes-St. Lawrence River Basin Water Resources Council (the Compact Council) regarding the Compact Council’s June 21, 2016 decision to approve the City of Waukesha’s application for a diversion of Great Lakes Basin Water. The Waukesha diversion is the first-ever diversion of Great Lakes water approved under the 2008 Great Lakes-St. Lawrence River Basin Water Resources Compact (the Compact). Under the approved diversion, the City of Waukesha can divert up to 8.2 million gallons per day (annual average demand) from Lake Michigan.

On March 20, 2017, after extensive briefing by the Cities Initiative and the City of Waukesha, the Compact Council held a hearing and allowed oral argument by the parties. The Cities Initiative is a binational coalition of 127 U.S. and Canadian mayors and local officials, representing over 17 million people, working to advance the protection and restoration of the Great Lakes and St. Lawrence River. The Cities Initiative argued that the Compact Council should reconsider its decision to grant the diversion and clarify the standards used to evaluate the Waukesha diversion application as well as the standards it will use to evaluate diversion requests in the future. The City of Waukesha argued that the Compact Council acted reasonably to approve the diversion.

The Compact Council took the matter under advisement at the close of arguments and indicated it likely will issue a written decision in early May.
