Know before you go real river conditions, not raw numbers.
Translating 300+ hand-picked USGS telemetry gauges into confident, plain-English flow verdicts. (Phase 1: Rapidly expanding across the US!)
Stop guessing if 850 CFS means a rocky scratch or a raging washout.
Hydrologic numbers alone don't reveal if a run is floatable for drift boats or dangerous for open canoes. ClearGauge cross-references live gage heights against reach-specific gradient profiles and community-calibrated runnability bands.
How ClearGauge translates raw telemetry into action
Federal stream gauges output discharge rates and pressures every 15 minutes. We convert those sensor pings into clear operational verdicts.
Live Sensor Readings
Every 15 minutes, USGS sensors measure how much water is flowing and how high the river is sitting. We pull data automatically from 300+ hand-picked priority stations.
30-Year Comparison
We compare today's flow to 30 years of historical averages for that same time of year, so you know if the river is higher or lower than normal — not just what the number is.
Plain-English Answer
You get a clear, simple verdict: Low, Normal, High, or Flood Risk — plus specific guidance for kayaking, fishing, or boating. No math required.
