Culvert Inventory Application Suite

The DNR Culvert Inventory Application Suite is comprised of 4 related components for the collection, storage, edit/review and distribution of stream crossings, culverts, bridges, and breach line data. It was developed by the MNDNR GeoSpatial Water Resources Team (gWRT) in partnership with MNIT at DNR professional services staff. This application is available to DNR Staff and external partners (free registration required).
