NBEP Study Areas 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. This dataset represents the watershed boundaries for the three estuaries, i.e., the areal extent of surface water drainage to the three estuaries, based on topographic, hydrologic, and other relevant landscape characteristics. This dataset is intended for use in general planning, GIS analysis, and mapping at watershed and subwatershed scales.
