2,105 miles of mapped stream across 1,415 square miles of drainage in Erie, Genesee, Niagara, Wyoming counties, in 51 named streams. New York designates 45 of those miles as trout water, on 7 streams.
Open in BirdTrout50°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.
HUC8 04270101 in the USGS Watershed Boundary Dataset. Every figure below adds up the river pages in this basin — same records, one basin at a time.
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 4% of this basin's stream miles (78.0 of 2,105); the rest is untyped and is drawn grey on the map above.
78.0 of the 78.0 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 4% of it.
All 51 of them, longest first. 2 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.
