Spatial data

The MPCA offers spatial data that can be used with geographic information system (GIS) software to make maps or perform other geography-based functions. Regulatory, cleanup, and monitoring programs create and maintain spatial data used to protect and improve the environment and human health.

Many of these resources also include comma-separated values (csv) files that do not require GIS software.

Featured datasets

Impaired waters

Dataset of MPCA's list of impaired waters (also known as the 303(d) list) that do not meet water quality standards, which is refreshed every two years. The EPA reviews this list and may approve or disapprove of new listings.

Assessed waters

Dataset of MPCA's list of the waters that they have assessed to determine whether they are healthy enough to support recreation activities, aquatic life, and water supply use. This is also known as the 305(b) integrated report.

Feedlots in Minnesota

Dataset contains point representations of the locations of animal feedlot facilities in Minnesota. The data includes contact information, registration/permit information, animal counts, animal units, and information about nearby waterbodies.

Wastewater datasets

Multiple datasets are available related to municipal and industrial wastewater facilities. Wastewater permits have spatial data for both the facility and monitoring locations. The MPCA publishes these data in both spatial and tabular formats.

MPCA water quality monitoring stations

MPCA surface water monitoring station locations and related data.

Municipal separate storm sewer system (MS4) permit holders

MS4s are publicly owned or operated infrastructure, such as curbs, ditches, culverts, stormwater ponds, and storm sewer pipes. The MS4 dataset shows the areas covered by MS4 permits, which often coincide with city boundaries.

Remediation datasets

  • MPCA remediation sites has information about leaks, emergency response, petroleum brownfields, non-petroleum brownfields (Voluntary Investigation and Cleanup), Superfund, RCRA, integrated remediation, and site assessment sites.
  • MPCA institutional controls (ICs) show areas with land use restrictions — conditions or controls that are intended to minimize exposure to contamination.
  • Minnesota Groundwater Contamination Atlas allows users to view groundwater areas of concern for some remediation sites.

What's in my Neighborhood

The What's in my Neighborhood site shows information about regulated facilities and clean-up sites, past and present. This dataset includes site names and addresses for all of the points on our map, along with links to the site pages where you can find detailed information.

Statewide Altered Watercourse Project

This project to create a statewide inventory of streams that have been "hydrologically altered" (channelized, ditched, or impounded) was a joint effort of the MPCA and the Minnesota Geospatial Information Office. The dataset was created to support MPCA's water quality monitoring and assessment program and provides information about stream habitats that have been compromised through such alterations.

Raster data layer: Environmental benefits index top five percent areas (EBI300T5)

This layer identifies areas in Minnesota that have high potential for precipitation runoff and soil erosion. The layer is based on the Environmental Benefits Index (EBI) data layer developed by the Minnesota Board of Water and Soil Resources and the University of Minnesota. MPCA watershed division staff created the EBI300t5 data layer by selecting the five percent of the area of each major watershed (HUC8) in Minnesota with the highest EBI scores. Reclassed land cover data from the 2011 National Land Cover Database was then input as the grid cell value for the highlighted areas.
