The Waterbody Inventory/Priority Waterbodies List (WI/PWL) is an inventory of the state's surface water quality. The dataset provides a summary of general water quality conditions, tracks the degree to which a water body supports its designated uses, and monitors progress toward the identification and resolution of water quality problems, pollutants, and sources. The category of No Known Impact represents 'segments where monitoring data and information indicate that there are no use restrictions or other water quality impacts/issues.'

Watersheds that support coldwater dependent species.

Highest ranking (top 20th percentile) small watersheds important for protecting water quality based on biophysical characteristics.
