50°F and colder is cold, through cold-transitional and cool, to warm above 70°F — the same four bands, breaking at 58, 64 and 70°F, that the app paints. Grey is water nobody has measured.

Thermal classification

NYSDEC's classification of this water, reach by reach. A class, not a temperature — no July mean, because none was measured here.

Reach Typed miles Band NYSDEC type
RM 15.7–0.0 18.1 cold —

NYSDEC has classified 18.1 of the 65 miles NHD carries for this stream — 28% of it. Every typed reach carries the same class, cold. The untyped reaches are not warm water — they are water NYSDEC's inventory does not reach, and the mile ranges above span only the reaches it does.

Questions about this river

NYSDEC classification

NYSDEC classifies this water as Class B — swimming and contact recreation and Class C — fishing. More than one class appears because the classification changes along the river. The thermal bar above shows where. On those reaches DEC also designates it trout waters — which is the half of the classification that is about temperature, and the half this map paints by. The class is a designation of best usage under 6 NYCRR — what the water is protected for — and not the season and creel rules, which change yearly and live with the agency.
