The record at this gauge
The daily-value history could not be read from USGS when this page was built. The record
itself is not missing — we could not reach it, and it will be back here shortly. The live
reading above and everything below is unaffected.
The water it stands in
Monongahela River, classified Warm Water Fishes (Warm Water Fishes) by PA DEP — the nearest reach carrying that classification is 1.19 mi
from the gauge.

Where this comes from
The gauge and its readings — U.S. Geological Survey. Site metadata from our own
gauge records; latest values from the USGS OGC API's latest-continuous
collection; the history from its daily-values collection, five years, cached for a day.
Monthly means, records and the comparison to this date's normal are computed here from
that daily series, not published by USGS. Day counts are printed beside them.
Water temperature and streamflow — USGS instantaneous and daily values.
The number above is live, not the day this page was written.
Coldwater designations —
MDNR's VSEC river typing for
Michigan, WDNR's classified trout streams for
Wisconsin, VDWR's trout stream classes for
Virginia, NCWRC's Public Mountain Trout Waters designations for
North Carolina, MN DNR's Chapter 6264 designated trout stream listing for
Minnesota, PA DEP's Chapter 93 aquatic life uses for
Pennsylvania, Ohio EPA's aquatic life uses under OAC 3745-1 for
Ohio, NYSDEC's 6 NYCRR classification and trout designation for
New York, and WV DEP's Category B-2 trout water designations under 47 CSR 2 for
West Virginia.
Each is that state's own classification, not this
site's judgement, and the page names which one it read.
Public land — PAD-US, joined per region. Private inholdings inside a public unit
are excluded from the green wash on the map.
Fly shops — OpenStreetMap, with hours and phone where the shop publishes them.
Page built 2026-09-24. Readings are USGS provisional data unless USGS has finalised them, and provisional data is subject to revision. Statistics here are computed from the last five years of daily values at this gauge only — they are not USGS-published normals, and the day counts behind each one are printed so you can judge them.
