Station and river observations

METAR/SPECI uses the existing AviationWeather.gov bulk cache over the lower 48 and its margin. NWPS retains only gauges in the existing action-stage-or-above observed list; forecast-only gauges can have no observation. Absence never establishes zero wind, low water, or safe conditions.

Stage in this gauge’s units, not a regional flood depth. Tide/lake gauges remain water levels; datum is not supplied by this feed. Historical observations and the latest forecast keep separate times.

Retained observations: 1; target 24 hours, at most 96 reports per station. Recording began 2026-10-17 06:15:05.234Z; oldest available reading 2026-10-17 07:45:00 UTC.

Observed stage and separate NWS forecast at GFZM7 (ft)Dots are retained observations. Lines break for missing fields, long intervals or changed station location or units. 0 recorded discontinuities. Dashed lines, when present, are the separately issued NWS forecast.24.522.5ft10-17 07:45Z10-17 08:45Z2026-10-17 07:45:00 UTC · 23.52 ft

NWS forecast · current

No forecast maximum supplied.

Graphical forecasts are not available during times of high water, forecast crest information can be found in the local WFO web page.

Gauge thresholds: action 13 ft; minor 15 ft; moderate 20 ft; major 25 ft.

NWS gauge impact statements
  • 25 ft: Approximate level of the one percent chance flood. Highway O across and near the river will likely flood.
  • 20 ft: Highway O on the west side of the river will begin to flood.
  • 15 ft: Low lying areas on the north and west side of the river begin to flood.

Capture times, quality and provenance

Each report keeps its observation time, first capture of this version, and the SHA-256 of the source bulk body. Corrections at the same observation time replace that point and are marked; unrelated bulk-file changes do not freshen a report.

  • Observed 2026-10-17 07:45:00 UTC, captured 2026-10-17 09:45:05.916Z; source body SHA-256 0d8a80be93500a5f3bdc37d2e564df5d4898bc27d32306a97751b1cd420138f9.

Only observed gauge records enter this history. Forecast maxima and forecast hydrograph points never become observations. A missing datum or unsupported flow value remains unknown.
