Ground Water GIS Data for Minnesota

• Hydrogeologic Maps of Minnesota (MGS, LMIC)
  These maps are part of the MGS "State Map" series; scales are 1:500,000 to 1:1 million.
   
  • Bedrock Hydrogeology
  • Quaternary Hydrogeology
    Geologic classification of the hydrogeologic (water-bearing) units for Quaternary (surficial, unconsolidated) deposits.
     
• Ground 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)
  • Digitized Location Points - 2009
    Points have been field-verified and digitized or GPS'd.
  • Calculated Location Points - 1998
    Points for wells which had not been field-verified as of December 28, 1998. Each location is calculated based on the reported PLS location of the well.
     
• 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 protection areas.
   
• Ground Water Contamination Susceptibility in Minnesota (MPCA, LMIC)
  A 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).
   
• Water Use - Water Appropriations Permit Program (DNR Waters)
  Water use permit information reports, location map and shapefiles of water appropriation installation locations.

• County Geologic Atlases and Regional Hydrogeologic Assessments
  Described on LMIC's geology information website. See especially "Part B" which covers hydrogeology and ground water sensitivity information.
   
• MetroGIS Datafinder
  Links to Washington County surficial geology and aquifer sensitivity files.
   
• MGS Current Publications
  Lists localized studies, maps and reports, some including GIS data.
   

Twin Cities Metropolitan Area

• Metropolitan Area Ground Water Model (MPCA, Met Council)
  The Metro Model is a regional ground water flow model encompassing the Twin Cities seven-county Metropolitan area. The GIS data is made up of paleozoic geologic coverages, hydrogeologic calibration databases, ground water contours, shapefiles of surficial hydrography and political boundaries and scanned topographic maps.
   
• Geologic Info for the Groundwater Management of the Northwestern Twin Cities Metro Area (MGS)
  The hydrogeologic investigation focuses on detailed characterization of the Upper Cambrian aquifer commonly referred to as the “Franconia-Ironton/Galesville” or “FIG” aquifer. GIS data includes DEMs of selected bedrock surfaces and shapefiles of bedrock geology, bedrock topography, faults and unit boundaries.
   
• Geologic Info for the Twin Cities Area Metropolitan Council Water Supply Master Plan Development - Phase I (MGS)
  Information, data and grids describe the subsurface geology and the groundwater recharge potential of a subarea of the glacial geology map.
   

Southeastern Minnesota

• Karst Features of Minnesota
  Links to karst information are on MnGeo's geology information website.
   

Fargo-Moorhead Region

• Geological Mapping and 3D Model of Deposits that Host Ground-water Systems in the Fargo-Moorhead Region, Minnesota and North Dakota (MGS)
  This report, accompanying maps and 3D model depict the sediments and rocks that host ground-water systems across this region. GIS data includes point layers for drill holes, geologic material samples and other site information; other layers used to generate surficial and bedrock geology maps; and DEM models of stratigraphic units.
