The Minnesota Hydrogeology Atlas (MHA) series was created to compile and update existing data developed by the County Geologic Atlas program.
The new atlases reflect current data and methods statewide, though some map layers will still contain legacy data that may not match the current standard product and methods.
It can be used to evaluate the distribution of groundwater in the state, for water appropriation applications, and to guide the sustainable use of groundwater. It will also assist in geophysical, karst and other hydrogeological investigations.
Refer to the County Atlas for associated reports and additional information.
