Niagara River/Lake Erie WI/PWL

Niagara River/Lake Erie Basin Map

This is the most current Waterbody Inventory/Priority Waterbodies List (WI/PWL) water quality assessment information for the waters of the Niagara River/Lake Erie 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 water body 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.

A summary assessment of overall water quality in the Niagara River/Lake Erie Basin was completed in September 2010. This basin summary may not reflect more recent reassessment of some individual waterbodies.
