USGS gauge — live water temperature

Water temperature — the colour of every stream in the basin

58 64 70

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.

The watershed in numbers

HUC8 02020007 in the USGS Watershed Boundary Dataset. Every figure below adds up the river pages in this basin — same records, one basin at a time.

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 30% of this basin's stream miles (621.1 of 2,088); the rest is untyped and is drawn grey on the map above.

• Cold 621.1 mi (100%)

621.1 of the 621.1 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 30% of it.

Every named stream in the basin

All 91 of them, longest first. 17 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.

Public land in the watershed

75,222 acres in 22 units, which is 9.9% of the 760,451 acres the basin covers. Private inholdings carried in the same source file are excluded, here and on the map.
