USGS gauge — live water temperature
Water temperature — the colour of every stream in the basin

50°F and colder is cold, through cold-transitional and cool, to warm above 70°F — the same four bands the app paints. On this map the colour is NYSDEC's own classification of the stream, not a measurement, except at the gauge dots, which read live. Grey is water NYSDEC has not typed.

Cold, cool and warm water

NYSDEC classifies every surface water in New York under 6 NYCRR Parts 800-941, and the class is a best usage — what the water is protected for — rather than a temperature. The temperature statement is the (T) or (TS) suffix beside it: the water DEC designates for trout, or for trout spawning, which 6 NYCRR 704.2(b) protects with a 70 °F ceiling on any discharge. That suffix is what this page counts and what the map paints by; the class letter is printed beside it and is not a thermal grade. It covers 19% of this basin's stream miles (328.8 of 1,763); the rest is untyped and is drawn grey on the map above.

328.8 of the 328.8 typed miles in this basin — 100% — are cold or cold-transitional water. Every typed reach carries the same class, which is as likely to be the coverage as the water: NYSDEC has typed 19% of it.

Every named stream in the basin

All 95 of them, longest first. 4 have a page of their own and are linked; the rest are in the app. The class column is NYSDEC's designation of that stream. "Now" is the live USGS reading where a gauge stands in that stream.
