Hudson River, New York
14.2 mapped river miles, draining 1,657 square miles, in the Upper Hudson basin watershed.

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. It is the same classification the map paints from, and it is a class, not a temperature: no July mean appears on this page because none was measured on this water.
| Reach | Typed miles | Band | NYSDEC type |
|---|---|---|---|
| RM 14.2–9.6 | 48.4 | cold | — |
NYSDEC has classified 48.4 of the 91 miles NHD carries for this stream — 53% 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.
NYSDEC classification
NYSDEC classifies this water as Class AA — drinking water source 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.

Hudson River sits in HUC 8 02020001, the Upper Hudson basin, and drains 1,657 square miles, Strahler order 7 at the mouth. 314 NHD reaches carry the name for 90.7 miles in total — more than the 14.2 miles of drawn mainstem, because NHD counts side channels and braids as their own reaches.
