This data set provides the water quality classifications of New York State's lakes, rivers, streams and ponds, collectively referred to as waterbodies. All water bodies in the state are provided a water quality classification based on existing, or expected best usage, of each waterbody or waterbody segment. Under New York State's Environmental Conservation Law (ECL), Title 5 of Article 15, certain waters of the state are protected on the basis of their classification. Streams and small waterbodies located in the course of a stream that are designated as C (T) or higher (i.e., C (TS), B, or A) are collectively referred to as "protected streams."
