National Wetlands Inventory

The USFWS provides information to the public on the extent and status of the nation’s wetlands. The agency has developed a series of topographical maps to show wetlands and deepwater habitats. This geospatial information is used by Federal, State, and local agencies, academic institutions, and private industry for management, research, policy development, education and planning activities. National Wetlands Inventory digital data can be viewed and downloaded through several methods. Explore the Wetlands Mapper here.
