The Compact entered into by all eight States and approved by the U.S. Congress prohibits diversions of Great Lakes water with limited exceptions. Those exceptions are for:
- Communities that straddle the basin divide
- Intra-Basin Transfers
- Communities in counties that straddle the basin divide
Depending on the type of exception sought, any proposal for a diversion of Great Lakes-St. Lawrence River Basin Water may need to undergo review by the Regional Body and may require approval by the Compact Council. To date, only the City of Waukesha's proposal for a diversion has undergone such review and approval.
