Bay Segment Boundaries NBEP2017 (shapefile)

Narragansett Bay, Little Narragansett Bay, and the Southwest Coastal Ponds are the three estuarine study areas under the purview of the Narragansett Bay Estuary Program (NBEP). This dataset represents all coastal waters and the coastline of Rhode Island and portions of coastline in neighboring Connecticut and Massachusetts, segmented according to all available information and the most common delineations of NBEP’s study areas. It includes the estuaries, the salt ponds, and estuarine tributaries. Segments are the smallest divisions of the Bay used for analysis in the 2017 State of Narragansett Bay & Its Watershed Technical Report (nbep.org). This dataset was created for the 2017 Technical Report and is intended for use in general planning, GIS analysis, and mapping at watershed and subwatershed scales.
