v1.1 is here: forecast-based Sweet Spot Alerts, flood stage lines on charts, upstream & downstream navigation, improved sharing, and NWS weather warnings integrated.
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 gages.
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 gages 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 NOAA and USGS monitoring stations. Water level in feet, discharge in CFS, flood stage classification, and trend direction — all updated continuously.
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.
Sweet Spot Alerts
Set your ideal flow or gage height range for any station. RiverTrax watches the NWS 5-day forecast and notifies you when your window is coming — so you know days in advance, not the morning of.
Get Warned Before It Happens
Configure per-station alerts for flood stage, discharge in CFS, or gage 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, gage 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.

v1.1 — Sweet Spot Alerts, Flood Stage Lines & More
The big one: Sweet Spot Alerts. Tell RiverTrax your ideal flow or gage height range, and we'll watch the NWS 5-day forecast and let you know when your window is coming. No more checking the app every day hoping conditions line up — we'll ping you when it's time to go.
Flood stage lines are now drawn right on the charts. Major, Moderate, Minor, and Action thresholds show up as labeled lines so you can see at a glance where current and forecasted levels sit relative to what actually matters.
Upstream and downstream navigation is here. From any station detail page you can now jump directly to the next gauge up or down the river — no more hunting through search to find a neighboring station.
A few other things we cleaned up:
· Alert configuration got a full redesign. Setting up a water level or flow alert is now clearer, and the new layout makes it easier to see what you've configured at a glance.
· Foreground monitoring now works. Alerts fire even when the app is open — previously you'd only get notified when RiverTrax was running in the background.
· Current conditions got some improvements — NWS weather warnings now show inline with station data, so you see active flood or weather alerts without leaving the station view.
· Sharing is better. Charts and station info share with cleaner formatting and more useful context attached.
Thanks for using RiverTrax. More coming.
