Know if the river is worth the trip today.

USGS shows 223 cfs. The flow has been stable 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 96 cfs and the upper quartile near 234 cfs; today's flow is on the high side 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. This is near the high side of normal, so be careful about wading, clarity, and pushy current before calling it good.

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 24 at 10:28AM PDT until September 25 at 10:00PM PDT by NWS Reno NV. Check public safety sources before going.
