iPhone
Your river changes by the hour. RiverTrax tells you what it's doing right now — and what it's about to do.
Live readings from thousands of USGS and NOAA gauges — water level, discharge, flood stage, and trend direction. Whether you're an angler, kayaker, rafter, or property owner watching for rising water, know the river before you go.
FOR ANGLERS
Track conditions before you go, see recent observations and forecasts for your favorite gauges.
FOR KAYAKERS & RAFTERS
See current discharge and whether it's rising or falling. Set your ideal flow range and let Sweet Spot Alerts tell you when conditions are lining up — before you drive to the put-in.
FOR PROPERTY OWNERS
Monitor gauges near your home or land. Know when to move vehicles, check drainage, or call for help — before water gets where it shouldn't.
FEATURES
Every Gauge, Right Now
Live readings from thousands of USGS and NOAA monitoring stations. Water level in feet, discharge in CFS, flood stage classification, and trend direction — all updated continuously.
Your Rivers on Your Home Screen
Pin your favorite gauges to your iPhone home screen with the new RiverTrax widget. See live discharge, gauge height, and trend direction at a glance — no app open required. Tap the widget to jump straight to full details.
Charts You Can Actually Read
See observed discharge plotted alongside official NWS forecasts on a clean timeline chart. Flood stage thresholds — Major, Moderate, Minor, and Action — are marked right on the chart so you can see where the river stands relative to what actually matters. Tap once to switch the chart to the extended 10-day outlook when you're planning further ahead.
Sweet Spot Alerts
Set your ideal flow or gauge height range for any station. RiverTrax watches the forecast and notifies you when your window is coming — so you know days in advance, not the morning of. When NWS hasn't issued an official forecast, RiverTrax falls back to extended outlooks so you stay informed even during quiet weather. Estimated alerts are clearly labeled.
Get Warned Before It Happens
Configure per-station alerts for flood stage, discharge in CFS, or gauge height in feet. RiverTrax monitors in the background and notifies you when thresholds are hit.
Follow the River
Navigate directly to upstream and downstream gauges from any station — follow conditions up or down the watershed without going back to search.
River Journal — Only on RiverTrax
Write a note on any station and RiverTrax automatically stamps it with the exact conditions at that moment — discharge, gauge height, and rate of change. Build a personal history of every day on the river, run or float trip, or flood event.
Up and Running in Minutes
No account required. No setup. Find your river, save your favorites, and go.

Ratings & Reviews
What's New in Version 1.4
This update makes finding and tracking your rivers faster and more reliable.
Better Search
Station search is fixed and more accurate — search by state, river, or place name and get the gauge you're looking for.
Refreshed Station Data
We rebuilt our station database from the latest NWS/USGS sources, adding new gauges and updating metadata across the country. The app is also noticeably smaller and quicker to install.
Redesigned Journal
Logging a trip or observation is cleaner now: a single focused entry screen, a new tap-to-rate star control, and visible tags so you can organize your notes your way. We also fixed a few rough edges, including an occasional "-0.00" reading and a bug that could overwrite a note after editing.
Fixes & Polish
Fixed the alert configuration button on the station screen
Improved the shareable station card
General stability and performance improvements
As always, thanks for using RiverTrax. Send feedback anytime — we read all of it.
