Water Use Data

Michigan and the other states and provinces in the Great Lakes Region have enacted laws that require major water users to report water usage within the Great Lakes Basin.  This information provides an environmental baseline for managing water resources in a more integrated manner and strengthens the legal basis for opposing unwarranted diversions of Great Lakes water to other regions of the country.
