Ground Water GIS Data for Minnesota
This webpage contains links to downloadable ground water GIS data for Minnesota.
The data is usually accompanied by a report or project on ground
water or geology but may be standalone. The page is organized by geographic scope:
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.
Minnesota Groundwater Tracing Database
Collection of dye input points, inferred groundwater flow vectors,
descriptive attribute data, and springshed delineations.
Minnesota Spring Inventory (DNR)
The project is creating a database and online map of spring locations.
