Lake Champlain WI/PWL

Grey colored NYS map with Lake Champlain Basin in yellow

This is most current Waterbody Inventory/Priority Waterbodies List (WI/PWL) water quality assessment information for the waters of the Lake Champlain Basin. The assessments are based on data and information collected through the 2008 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 segment Fact Sheets are grouped together by smaller watershed (10-digit Hydrologic Unit Code, or HUC10 Watershed). Use the map and HUC10 index below to find, view and download the water quality assessment information for the waterbody of interest to you.
