Mississippi River Information Network

This page provides links to online GIS data that can be directly downloaded from our servers and from other sources. We hope that the selection of GIS data sets that we present here will be helpful in your efforts to manage for clean water and sustainable resources in the Upper Mississippi River Basin.

New GIS data resources will become available for download through the Upper Mississippi Basin Stakeholder Network website as time and funding permits.
