Disclaimer: The wetland information was obtained by the US Fish and Wildlife Service using high altitude aerial photography. The wetland types were classified in accordance with Classification of Wetlands and Deepwater Habitats of the United States (FWS/OBS - 79/31 December 1979). The aerial photos were taken in the early 1980s. Due to the margin of error inherent in aerial photograph interpretation and the number of years having passed since the information was gathered it is recommended that a visit to the site be made in order to verify the information found on the map or digital database.
