For general questions about the Wetlands Mapper, accessing wetlands data, or our website, please email your inquiry to wetlands_team@fws.gov.
Please note: The wetlands displayed on the Wetlands Mapper show wetland type and extent using a biological definition of wetlands and are mapped using a specific date. There is no attempt to define the limits of proprietary jurisdiction of any Federal, State, or local government, or to establish the geographical scope of the regulatory programs of government agencies, or to account for changes in the landscape that may have occurred after the wetland data were produced.
Persons intending to engage in activities involving modifications within or adjacent to wetland areas should seek the advice of appropriate federal, state, or local agencies concerning specified agency regulatory programs and proprietary jurisdictions that may affect such activities.
For information about regulations that may affect wetlands or development on your property, contact the U.S. Army Corps of Engineers office nearest you: Army Corps of Engineers Office Locations.
