This team built case studies of how a public water supply and two industrial water users could meet increased demand for Great Lakes basin water while complying with requirements of the 2001 Annex to the Great Lakes Charter. The project team held panel discussions for the municipal, industrial manufacturing, and two industrial power scenarios. Team members created case studies for each scenario. For Municipal and Industrial scenarios, team members shared summaries, final results and supporting materials with the Governor’s Working group and other Annex project team members.
