RiverTrax pulls live readings from USGS and NOAA gauges nationwide — water level, discharge, flood stage, and trend direction. Set your ideal range and let Sweet Spot Alerts tell you when conditions are lining up.
Whether you're planning a float, scouting flows before a drive, or watching a gauge near your property — RiverTrax gives you the data that matters.
Check discharge, gage height, and trend direction before you drive two hours to the river. Know when conditions are right before you load the truck.
See current discharge in CFS and whether it's rising or falling. Get to the put-in when flows are in your sweet spot — not at flood stage, not too low to float.
Monitor gauges near your property. Know when to move vehicles, check drainage, or call for help — before water gets where it shouldn't.
Feature 01
RiverTrax pulls live readings from thousands of NOAA and USGS monitoring stations. Water level in feet, discharge in CFS, flood stage classification, and trend direction — all in one place, updated continuously. Navigate directly to upstream and downstream gauges from any station to follow conditions along the watershed.
Feature 02
See observed discharge plotted alongside official NWS forecasts on a clean timeline chart. Flood stage thresholds — Major, Moderate, Minor, and Action — are drawn right on the chart so you can see where the river stands relative to what actually matters.
Feature 03
Set it once. RiverTrax monitors your stations around the clock — live readings and NWS forecasts — and notifies you when your threshold is crossed. The screenshot above is real: a forecast warning and a flood confirmation, delivered automatically to the same phone while the Kaskaskia was rising.

Feature 04 · 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 run, scout trip, or flood event. No other river app has this.
Five alert types. Any station. Fully configurable — flood stage, discharge, gage height, or your personal Sweet Spot range, above or below any threshold you set.
NWS flood stage thresholds are built in — Action, Minor, Moderate, and Major. Monitor current conditions or forecasted flood stage without having to look up the numbers yourself.
Set an alert when flow is above, below, or between a range in cubic feet per second. Great for knowing when your run is in optimal range — or dangerously high.
Monitor exact water level in feet. Works with the same above / below / between logic as discharge — per station, per measurement type, fully independent.
RiverTrax doesn't just check what the river is doing now — it checks what the NWS forecast says it will do. Get a warning before dangerous conditions develop, not after.
Set a minimum and maximum flow or gage height — your ideal paddling window, fishing conditions, whatever your sweet spot is. RiverTrax watches the NWS 5-day forecast and notifies you when conditions are predicted to fall in your range. Know days ahead, not the morning of.
No account. No setup. Find your river, check conditions, and go.
Find any USGS or NOAA monitoring station by river name, location, or state. Save your favorites for quick access.
See live water level, discharge in CFS, flood stage classification, and whether the river is rising, falling, or steady.
Configure a threshold and RiverTrax notifies you when conditions hit your mark — no more checking manually.
