15.3 mapped river miles, draining 48 square miles, in the Lower New basin watershed. 1 USGS gauge report water temperature on it, and this page reads 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.
Live from the USGS — every pill above is live, so the numbers you are reading are the latest continuous readings at each gauge. Provisional and unreviewed, as all real-time data is. If that fetch cannot happen — you are offline, or the USGS is down — the pills fall back to the last value we cached, 30 September 2026, 14:07 UTC.
The pills above go to USGS. These are this site's pages for the same gauges — a thirty-day chart, the monthly means, the record, and today's reading against the five-year normal for today: 03185400.
Nobody has classified this water's temperature.WV DEP publishes no temperature classification for this water. What it publishes is the Category B-2 trout water designation below — WV DEP's finding under 47 CSR 2 that a stream sustains a year-round trout population, which is a statement about the fishery rather than about the temperature it runs at. It is the state saying this water is worth recording; it is not the state saying the water is cold. So the bands below are drawn grey rather than coloured, and grey here means unmeasured, not warm. The one temperature on this page is the live reading from the nearest USGS gauge, 4.8 miles away.
Each gauge carries a July mean built from its own daily record — 2 Julys, 2019–2020, measured rather than modelled. A July mean is what decides which of the four bands a stretch of water belongs to, because July is when a trout river either holds or does not.
| Reach | July mean | Band | Groundwater |

Every gauge sits at the bottom of its segment, so each number is the warm end and the water above it runs colder. ±None °F on the fit.
WV DEP classifies this water as Trout waters — whole assessment unit. 47 CSR 2 defines trout waters as water that sustains a year-round trout population, and excludes by name water stocked every year that does not hold trout over — so this is a finding about a wild or holdover fishery rather than about the stocking truck. It is not the season and creel rules — those are WVDNR's, change yearly, and live with that agency.

River miles are measured above the mouth, along the mapped mainstem. The reach breaks are the gauges, which is also how the temperature model divides the river.

1 unit of public or open-access land touches this river, 54,591 acres in total. Acreage is the whole unit, not the part beside the water.

WV DEP designates this as trout water — Trout waters — whole assessment unit — without naming the species. No fish survey or stocking record for this water is in the files this site reads.
The measured record behind every temperature band on this page: the mean of the daily means for July, at each gauge, over the years USGS has one.

56 insects are recorded from the Virginia mountains, across the state line. No insect records in this dataset are filed under West Virginia, so these are the nearest ones — the same landscape and the same water, on the other side of the border, and not a survey of this stream or even of this state. Open the river in the app and the hatch panel will narrow it to the ones whose temperature window today's reading is inside.

And 42 more — the year-round records, mostly: midges, scuds and sculpins, which are in the water every day and are therefore never the news.
10 named streams meet this one. Confluence miles are above the mouth; the longest twelve are listed.
Dunloup Creek sits in HUC 8 05050004, the Lower New basin, and drains 48 square miles, Strahler order 5 at the mouth. 31 NHD reaches carry the name for 16.4 miles in total — more than the 15.3 miles of drawn mainstem, because NHD counts side channels and braids as their own reaches.
