Atlantic Ocean/ Long Island Sound WI/PWL

Atlantic Ocean/Long Island Sound Basin

This is the most current Waterbody Inventory/Priority Waterbodies List (WI/PWL) water quality assessment information for the waters of the Atlantic Ocean/Long Island Sound Basin. The assessments are based on data and information collected through the 2013 NYSDEC sampling season. Individual assessment Fact Sheets for some waterbodies may have been subsequently updated where appropriate to reflect more recent information.

In order to ease viewing/downloading, this information has been segmented into separate smaller files. Individual waterbody Fact Sheets are grouped together by smaller watershed (10-digit Hydrologic Unit Code, or HUC 10 Watershed). Use the maps (separate maps for New York City Waters and Nassau/Suffolk County Waters) and associated HUC 10 index below to find, view and download the water quality assessment information for the waterbody of interest to you.
