Appreciate being able to monitor river level as we depend on irrigation water, and we are in the flood plain.
★★★★★Ed S· Jul 6, 2025
I've been using this app for a few years now, it's simple and effective to check river gauges and get alerts ahead of possible flooding since I live in a flood plain next to the river it's crucial for me to know how high the rivers have risen.
★★★★★Fran Schmeltz· Mar 31, 2026
This app works well you always have to know the flow of the water for kayaking and fishing!
★★★★★Megan Dark· May 7, 2026
For 7 years I've used River App to monitor stream flow on the river that runs through my property. I love comparing seasonal and year-to-year variations. My favorite feature is the custom alarm function. I have it set to notify me when the river is flowing above its seasonal average, so I have a heads-up to prepare for possible flood conditions. For a small annual fee River App always works like a dream and doesn't inundate you with ads or hidden trackers. One of my favorite apps!

Go-to app for all things whitewater, really well put together app. Very much worth the yearly subscription for premium.
★☆☆☆☆Theresa Shay· Jun 27, 2026
Why pay extra when everything you pay for is available on Google Earth/ maps
★☆☆☆☆Jason Schulz· Mar 13, 2026
😂😂😂 so for what this app shows. I can look up on real river data. At least it gives you a months worth of levels and data. This app, 24hrs. What a joke!
★★☆☆☆James Leaveck· Jun 25, 2025
There are several locations that never show any data in southern Wisconsin, can this be updated?
