RiverFinn
Supported waters
73 river sections on 58 rivers, in 5 states.
Every stretch RiverFinn covers today, and every one of them is free in the app, in full. A section is a stretch of river with its own gauge, weather grid, rules and species — the unit the app rates and Finn talks about. A river with several supported stretches is listed once per stretch.

All of them on one map
Every supported stretch, with its current status and any agency closure on the pin itself — so a closed water reads closed before you tap it. One tap from there opens directions to the reach's verified coordinates, never to the gauge downstream of it.
Distance is straight-line. RiverFinn has no routing data and never claims a drive time.
Don't see your river?
Ask for it from inside the app. Requests are grouped by river and decide what RiverFinn investigates next — whether a water can be supported depends on gauges, thermometers and agency sources, so demand alone never adds one.
Every one of these, in your pocket.
All of them free in the app, in full — the rating, the readings and every closure. RiverFinn Pro adds the window, the plan and the ranking.
