Wetlands

The following layers of wetland data are provided to assist the public in planning projects in the Adirondack Park. The data may not show all wetlands that are present in an area or the precise boundaries of wetlands. For a determination on whether a wetlands permit is required, project planners are encouraged to contact Agency staff. It may even be necessary for Agency staff to visit the property in order to assess whether wetlands will be affected by a planned project and to determine if a permit is needed. For more information, consult our Freshwater Wetlands flyer.
