The following links are web sites where information regarding wetland location can be obtained. This data can be viewed spatially via the web or downloaded by quad/or state into a GIS program.
The most recently updated and quality checked wetland information can be found on the USFWS National Wetlands Inventory site, which has several options for downloading and viewing wetlands. To view the availability of wetlands data in your area click here.
The Montana Heritage Wetland and Riparian Mapping Center produces much of the wetland and riparian maps for Montana. Currently NWI does not provide riparian area maps. Maps of provisional wetland data and riparian areas may be available for areas not currently in the NWI data base and can be obtained by contacting the Montana Natural Heritage Program (406) 444-3380.
USFWS National Wetlands Inventory
NWI Wetlands Mapper
The NWI Wetlands Mapper allows you to download and view wetlands at a scale of 1:100,000 or less. Using the NWI Wetlands Mapper lets you download wetlands only in the immediate vicinity of the area you are interested in. Wetlands Mapper also has the capability of producing maps that can be printed.
NWI Wetland Extractor by Quad
This site allows you to specify wetland data to download in GIS shapefile format based on 1:24,000 or 1:100,000 USGS quads. It is not assured that wetland information is available for all quads. Click here to check for data availability.
NWI Wetland Extractor by State
This site allows you to download the most recent and quality checked statewide National Wetlands Inventory data in either a GIS shapefile format or Geodatabase.
View NWI Wetlands in Google Earth
You can now view wetlands data in Google Earth. Follow the WetlandsData.KMZ link on NWI Wetlands in Google Earth page.
