Everything a stretch of river can tell you.

Each of these is in the app today. None of them invents a number.

Current discharge from the gauge on the reach, refreshed every few minutes, with observation time and a link to the station.

Flow, trend, temperature and wind against the reach's species profile. Only when enough is measured; a hard limit like a 70 °F reading caps it.

Today's CFS, and how it compares with the gauge's long-term record for this date where enough years exist.

From a thermometer on the water, with its own observation time. Reaches without one say "no live reading".

Rising, falling or stable over the last six hours, from the same gauge.

National Weather Service forecast for the reach: highs, lows, wind and rain chance for today and the weekend.

Mandatory closures and voluntary advisories from state wildlife agencies, with the agency's own wording and link.

The standing rules for the stretch — gear, seasons, designations — from the managing agency, with a reminder to confirm before you fish.

A fishing guide that answers from RiverFinn's data about your rivers, and tells you when something is not measured.

Rivers near you ranked by what is measured, with advisories and closures always ahead of the arithmetic.

Keep the rivers you fish. Your weekend outlook, alerts and Finn all start from them.

Closures, advisories, temperature and flow thresholds, regulation changes and weekend outlooks, as notifications on your phone.

Tell Finn the day. RiverFinn picks the water and the hours, keeps the plan on your calendar with your own events, and flags changes.

One tap to the access point in your maps app, from verified coordinates — never a guessed spot.

Every screen can show where each number came from, when it was observed and when RiverFinn last checked.

Steelhead and salmon reaches carry their documented run windows and source instead of a score that would not apply.

Know before you go.

RiverFinn is free to start. Save a few rivers, ask Finn, and see what the water is doing before you drive.
