Description: These data contain the known outer boundaries for federally supported navigation projects in the northeast United States. Project areas include channels and anchorage areas that have required alteration of the waterway through dredging or other means. Other channel and anchorage areas, that do not require maintenance, can be found in complementary databases provided by NOAA and the Marine Cadastre. Please see NOAA nautical charts, the Electronic Code of Federal Regulations, and the United States Coast Pilots for controlling depth values for project areas.
