This map relies exclusively on U.S. Fish and
Wildlife Service's (FWS) National Wetlands
Inventory (NWI) data for mapping water resources
such as wetlands and deepwater habitats. Due to the
resolution of the map, it does not distinguish
consistently between land and water and thus makes
waters appear more prevalent than is actual. The
FWS' definition of "wetland" is broader than the
Clean Water Act definition. This map does not
depict the scope of waters protected under the Clean
Water Act or the scope of waters that would be
protected under the Army/EPA proposed rule. This
map has not been used for any regulatory purpose.
This map is based on NWI data available as of
January 2013.
