Know if the river is worth the trip today.

USGS shows 296 cfs. The flow has been falling about 13% over about 6 hours. USGS marks this reading provisional and may revise it. USGS records for this date (1919-2025, 107 readings) show a median near 88 cfs and the upper quartile near 193 cfs; today's flow is high for the date. USGS 01548500 at Cedar Run is flow context for the gorge corridor. It does not report current continuous water temperature, and neither flow nor air temperature can substitute for an on-site reading. USGS 01549700 at Waterville is a separate downstream gauge and must not be presented as Cedar Run temperature evidence. Fishable water may exist, but do not rate it highly without a safe access, clarity, and wading or boat plan.

BlueStreamFly cannot confirm whether the report-wide official restriction currently applies: Hoot-owl fishing restriction on the upper Madison River (Yellowstone National Park boundary downstream to Hebgen Reservoir). This does not establish that the restriction is currently active or that the water is legally closed. Do not use score-led guidance until the official source is checked.

An active alert is in effect: Red Flag Warning issued September 11 at 10:18AM PDT until September 13 at 2:00AM PDT by NWS Reno NV. Check public safety sources before going.
