Spatial data

Spatial data consist of coordinates (geographic or projected) that represent the physical location of a site or a site feature along with metadata that describe how and by whom those coordinates were collected.

The MPCA offers data and shapefiles for many of our data-based applications. The shapefile download includes both data and files that require geographic information system (GIS) software to make maps or perform other geography-based functions.

Check out the Minnesota Geospatial Commons for data and resources from MPCA and many other government sources.

Contains polygons representing Municipal Storm Sewer System permit holders (MS4s) regulated by the Minnesota Pollution Control Agency under the Phase I and II NPDES programs. The purpose of this data set is to provide a tool for maintaining information on MS4 permit holders, and for reporting and analysis by both permittees and the MPCA. The projection for this data layer is UTM Zone 15 North, NAD 1983.

Geographic data from the map-based search tool is available for download in a shapefile format, suitable for use with Geographic Information Systems (GIS) software. MPCA Water Quality Monitoring Stations (file size = 2.5 MB)

This dataset contains point representations of the locations of animal feedlot facilities in Minnesota. The attribute table includes information about the number of animals for each location.

This data set 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. If you just want a spreadsheet of these data, choose the Comma-Separated Values File. There is also a shapefile download, which includes files that work together to display information on a map. You need Geographic Information System (GIS) software in order to use the shapefile to make maps or perform other geographic-based functions.

A polygon feature class used to map the spatial extent of Total Maximum Daily Load (TMDL) projects and Watershed Restoration and Protection Strategy (WRAPS) areas in Minnesota. MPCA water resource staff identified Total Maximum Daily Load (TMDL) and Watershed Restoration and Protection Strategy (WRAPS) project boundaries as a central data element for the agency. A team of staff from the MPCA Watershed Division and the MPCA Information Systems Office worked together to collect and store this data in a central repository and distribute it to MPCA partners as needed. The team designed a geospatial database, developed a user guide, and developed communication and distribution strategies for the database. The resulting geospatial database is maintained by the MPCA Watershed Division and polygons are included in the database for all EPA-approved TMDL/WRAPS projects.

Map shapefiles which represent the Minnesota 2012 assessments (per Section 305(b) Clean Water Act), including lakes, streams, and wetlands. These files were created for those interested in preparing computerized maps of the 305(b) assessments. To use these files you will need Geographic Information System (GIS) computer software. The zipped file contains shapefiles for use support (aquatic recreation, aquatic life, and aquatic consumption). The projection for the shapefiles is UTM extended zone 15, NAD83. The shapefile was created by the Minnesota Pollution Control Agency using the 1:24,000 scale National Hydrography Dataset.

Map shapefiles which represent the current Inventory of Impaired Waters (per Section 303(d) Clean Water Act), including lakes, streams, and wetlands. These files were created for those interested in preparing computerized maps of impaired waters. To use these files you will need Geographic Information System (GIS) computer software. The zipped files contain a separate shapefile for lakes, streams and wetlands, including metadata. The projection for these shapefiles is UTM extended zone 15, NAD83. These shapefiles were created by the Minnesota Pollution Control Agency using the 1:24,000 scale National Hydrography Dataset (NHD).

This is a proposed set of the waterbodies assessed by MPCA's surface water quality assessment process for the 2016 303(d)/305(b) integrated report to EPA. The waterbodies included in the dataset were submitted to EPA in January 2017. EPA evaluates the data and either approves it as-is or modifies it, which may result in changes to this spatial data.

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 (BWSR) and the University of Minnesota. More information about the EBI is available from the BWSR web site. 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 (NLCD) was then input as the grid cell value for the highlighted areas.

This is a draft set of the impaired waterbodies as determined by MPCA's surface water quality assessment process in 2016 and 2017 for the 2018 reporting cycle to U.S. Environmental Protection Agency (EPA). Waterbodies declared impaired prior to 2018 are also included in this dataset unless they have been delisted. The waterbodies included in the dataset were submitted to EPA in April 2018 as part of the impaired waters list. EPA evaluates the list and either approves it as-is or modifies it, which may result in changes to this spatial data.

Lakes assessed by MPCA in 2009 for the 2010 reporting cycle to U.S. EPA. The lakes are a subset and enhancement of the 1:24,000 scale National Hydrography Dataset (NHD). MPCA adds additional lakes. Since the assessed lakes are a small subset of the NHD waterbodies, only that subset is included in the dataset.
