Know if the river is worth the trip today.

USGS 01548500 at Cedar Run reports flow but not current continuous water temperature. Measure the exact reach with a stream thermometer. Choose another water at 70°F or warmer.

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.

USGS shows 367 cfs. The flow has been stable over about 6 hours. USGS marks this reading provisional and may revise it. USGS records for this date (1907-2025, 103 readings) show a median near 221 cfs and the upper quartile near 338 cfs; today's flow is high for the date. USGS 10348000 measures the regulated Truckee River mainstem at Reno. Its flow, stage, and turbidity describe the urban Reno reach, but the gauge does not report current continuous water temperature, prove safe wading, or confirm each park access. A downstream Sparks temperature reading is context only and cannot clear the Reno reach. Fishable water may exist, but do not rate it highly without a safe access, clarity, and wading or boat plan.
