Water rights are of single importance in the Great Lakes region. Of primary concern are the various laws that govern the allocation and use of water. Virtually every Great Lakes state has its own rich history of judicially resolved water disputes. These disputes have occasioned the generation of a common law of waters and water rights which are often supplemented by statutes. Not only is this true for surface waters, it is also true for groundwater. It is the groundwater resource that this article addresses.
