WATER QUALITY for Recreation - Rivers and Streams 2014 NBEP2017 (shapefile)

This vector dataset contains water quality classifications for 2014 in the rivers and streams of Narragansett Bay, Little Narragansett Bay, and Southwest Coastal ponds watersheds. 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 recreational use with an emphasis on pathogen pollution. River and stream lengths are calculated in 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.
