Hydrogeologic Maps of Minnesota (MGS, LMIC)
These maps are part of the MGS "State Map" series; scales are 1:500,000 to 1:1
Water Provinces (DNR Waters)
Minnesota has been divided into six
ground water provinces based on bedrock and glacial geology that influence
ground water availability.
- County Well Index -- Well Location Points (MGS)
Points have been field-verified and digitized or GPS'd.
Source Water Protection Maps and Geospatial Data (MDH)
Wellhead protection maps, nitrate probability
maps and reports, and geospatial data for topics such as class 5
sensitivity, drinking water supply management areas and their vulnerability,
emergency response areas, source water assessment areas, and wellhead
Contamination Susceptibility in Minnesota (MPCA, LMIC)
generalized interpretation of ground water contamination susceptibility for
the state, based on modeling using data inputs from 40-acre gridcell soil and geology data, with additional geology inputs (note: DNR
has posted instructions for
estimating sensitivity at a more localized level).
Use - Water Appropriations Permit Program (DNR Waters)
Water use permit information reports,
location map and shapefiles of water appropriation installation locations.
Statewide Spring Inventory (DNR)
DNR is creating a statewide spring database using information from agency
records; citizens are encouraged to submit spring information as well.
