What's New in RiverTrax

1.8

September 20, 2026

Thousands more gauges are now in RiverTrax. Some USGS stations aren't in the National Weather Service forecast inventory — plenty of smaller creeks and tributaries fall into that gap. Those gauges now work in RiverTrax as observation-only stations: live readings and history, just without a forecast line on the chart. Alerts work on them too. Set your threshold and RiverTrax will let you know when a creek comes up or drops into range, same as any other gauge. — John

Great features

Great USGS water data app, tons of helpful features. The river journal, multiple types of flow alerts, instantly being able to jump up or down river from within a gauge are all so helpful and valuable. As a fishing guide, avid angler, and boater the only thing it is severely missing is water temps. Please add water temps and graphs where available ASAP!

Response from developer

Thanks for using the app and taking the time to review, I really appreciate it. I'm adding water temps for gages for the next release, I'm testing right now. Current temp will be on the favorite card right below flow and gage height so it's easy to find and also on the detail page along with a chart showing last 5 days of water temp history. Hopefully this works for you once it's released. Thanks again for the feedback.
