USGS River Levels & Flows Downloads & RevenueUSGS River Levels & Flows · App Store

Check any river in the United States — flow, stage, water temperature, and the National Weather Service forecast — from more than 10,000 official USGS gauges.

Built for the people who actually need the number: paddlers deciding whether a run is in, anglers reading a rise, and anyone who lives where a creek can come up overnight.


WORKS WHERE RIVERS ARE

Rivers are where cell signal isn't. Every gauge you star is saved to your phone, so the put-in with no bars still shows your last reading — clearly labelled with its age, never passed off as live. The entire 10,000-gauge catalogue is bundled in the app, so search and browse work with the radio off.


FREE, INCLUDING THE PARTS OTHERS CHARGE FOR

• NOAA forecasts — the predicted hydrograph, drawn on the same chart as the observations, up to five days out
• Years of history — 7 days, 30 days, 1 year or 5 years on any gauge
• Seasonal normals — what this river typically does in each month, so you know whether today's number is high, low, or ordinary for the season
• Flood categories — action, minor, moderate and major stages as published by the National Weather Service

No account. No subscription. No paywalled forecasts.


RIVER LEVELS PRO — ONE PURCHASE, YOURS FOR GOOD

Everything above stays free. One optional purchase removes the ads and adds the tools built on top of the data:

• Home screen widget — your gauges, their readings and your range status
• "Which of my rivers today" — every favourite ranked by whether it is in your range, nearest first
• Logbook — a note and a photo pinned to a gauge at the reading you saw, drawn on the chart
• Compare two gauges on one chart, and this year against last year
• Today vs. the record — where today sits against up to 30 years for this date
• Run sheets — group a put-in, a takeout and a tributary under one run with a combined go/no-go, and share it as a link or QR code
• Offline map packs — download the USGS topo or satellite map around a run
• Copy your ranges between gauges, export any chart as CSV, launcher shortcuts

HONEST ABOUT THE DATA

Readings come straight from the U.S. Geological Survey and NOAA's National Water Prediction Service. Both are public-domain federal sources, and this app adds nothing to them but the reading.
