资源简介：
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 areas of landscape that drain into NBEP’s estuarine study areas, divided by state boundaries. Coastal boundaries were updated with NBEP’s estuarine coastline delineation for analytical purposes. This dataset was created for the 2017 State of Narragansett Bay and Its Watershed Technical Report (nbep.org) and is intended for use in general planning, GIS analysis, and mapping at watershed and subwatershed scales.
