资源简介：
This vector dataset contains estuarine water quality classifications for 2014 in the Narragansett Bay, Little Narragansett Bay, and Southwest Coastal ponds. Water quality classifications were based on Massachusetts and Rhode Island Assessment Databases for 2014 (MassDEP 2015, RIDEM 2015). This assessment specifically focuses on causes of water quality impairment that are detrimental to aquatic life with an emphasis on nutrient enrichment and low dissolved oxygen. Area is calculated in square miles. 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 graphic display at watershed and subwatershed scales.
