FlowTracker was born from a simple need — knowing if the river was running without checking a phone or a cluttered USGS webpage.
To provide paddlers and river enthusiasts with the most accessible, reliable, and modern river monitoring solution. We bridge the gap between complex USGS data and actionable peace of mind.
FlowTracker is a wall-mounted display that polls the USGS National Water Information System and shows you real-time discharge (cfs) and gauge height (ft) for the rivers you care about. The device learns each gauge's update schedule and checks at exactly the right moment — never early, never late. No subscription. No app. Just a glance.
Each unit is built around a high-reliability ESP32 microcontroller paired with a large, high-contrast color display. Color-coded indicators — green for at or above your desired level, red for at or above your warning threshold — let you read conditions at a distance. Every unit is hand-assembled and tested.
No complex hydrology jargon. If the river is good, you'll know it.
Direct from USGS sensors. Accurate data, always current.
Clean, high-contrast visuals designed to be readable across the room.
