Download Seamless Wetlands Data by State

By selecting a State file below, you can download current seamless wetlands data as viewed on the Wetlands Mapper.

Before you begin

Each State data download is available as either a compressed file Geodatabase or a Shapefile. Both files are compressed by using the .zip format.

Not all of the United States and U.S. Territories have been digitally mapped by the U.S. Fish and Wildlife Service. Please refer to the Wetlands Mapper Wetlands Data Availability layer to view where wetlands have been mapped. Each download also includes a 'Public_Metadata' data layer that identifies where and when wetlands were mapped within the state.

NOTE: Due to the variation in use and analysis of this data by the end user, each of states wetlands data extends beyond the state boundary. Each state includes wetlands data that intersect the 1:24,000 quadrangles that contain part of that state (1:2,000,000 source data). This allows the user to clip the data to their specific analysis datasets. Beware that two adjacent states will contain some of the same data along their borders.

Coordinate System

All data downloaded is in the Albers projection with a North American Datum (NAD) of 1983.

Download time

Due to the amount of data being downloaded, the resulting processing time to prepare the download file may take up to 60 minutes or more, and can range in sizes from 1 to 463MB.
