USGS gauge — live water temperature
Water temperature — the colour of the river, and of every dot on it

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

There is no USGS gauge within 40 miles of this stream in the record this site holds, so there is no live temperature on this page and no measured July mean. Everything below the bar is NYSDEC's own classification of the water.

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 19.4–17.6 50.2 cold —

NYSDEC has classified 50.2 of the 133 miles NHD carries for this stream — 38% 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.

The lake run

The Black River is a Lake Ontario tributary with 1.5 miles of run corridor on it — salmon, steelhead and lake-run brown trout, on their own calendar and under their own rules. Run timing, species and access on the Black River →

Questions about this river

NYSDEC classification

NYSDEC classifies this water as Class A — drinking water source, Class C — fishing, and Class D — fishing, natural conditions limit the fishery. 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.
