4.4 mapped river miles, draining 6 square miles, in the East Branch Delaware basin watershed. A USGS gauge stands in it, but its record is too short for a measured July mean, so what this page knows about its temperature is today's reading and NYSDEC's classification of the water itself.
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.
The nearest gauge is 12.1 miles away, at Esopus Creek — not a reading of this water, but of what the region is doing today. A closer gauge has stopped reporting — it has sent no water temperature for 1366 days, since 1 January 2023, so no number here comes from it.
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 4.4–0.0 | 7.5 | cold | — |
NYSDEC has classified 7.5 of the 8.2 miles NHD carries for this stream — 92% 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 classifies this water as Class A — drinking water source, 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 spawning waters, 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.

NYSDEC designates this as trout water — Trout spawning waters, Trout waters — without naming the species. No fish survey or stocking record for this water is in the files this site reads.
4 named streams meet this one. Confluence miles are above the mouth; the longest twelve are listed.
Bush Kill sits in HUC 8 02040102, the East Branch Delaware basin, and drains 6 square miles, Strahler order 3 at the mouth. 31 NHD reaches carry the name for 8.2 miles in total — more than the 4.4 miles of drawn mainstem, because NHD counts side channels and braids as their own reaches.
