Organizations or individuals have the opportunity to contribute wetlands data to the wetlands geospatial data layer maintained by the U.S. Fish and Wildlife Service.
The Service will provide proper acknowledgement of all data contributors and maintain data integrity consistent with DOI policy.
The U.S. Fish and Wildlife Service has produced hard-copy maps for about 90% of the nation. Standard-sized 7.5' paper wetland maps (blue-line polygons shown on USGS blue-line topographic base, size 2' X 3') can be purchased through Cooperator-Run Distribution Centers.
Digital data available on this site represent the latest, most accurate information available from the U.S. Fish and Wildlife Service. These data are also available on The National Map. Geospatial One Stop provides access to maps, search options, articles, and other useful tools.
