Ask
Ask about
any river in
the country.
Type a question in plain words. It looks things up before it answers, and it tells you when it doesn’t know.
Ask about any river in the United States — what it’s running, whether it’s too warm to fish, what it looks like on camera right now, where the ramps are, or which shops are near you. If the trip runs past dark, ask where to camp and how far it is.

What it can look up
- Flow and water temperature — live, from any of 8,844 gauges, in all fifty states
- How that compares to normal — against the full record for today’s date, often fifty years or more
- River cameras — 873 of them; it can look at the picture and tell you what it sees
- The next three days — temperature, wind and rain
- Boat ramps and access points — 32,514 of them
- Fly shops — and which ones were checked by hand rather than pulled off a map
- The trip logs — what the numbers were on a given trip, and the fly that worked
Worth knowing
- Warm water beats a good flow. Above about 68°F a tired trout usually dies after release, even if it swims off. It will never call warm water fishable, whatever the flow says.
- It only has an opinion on five rivers. Everywhere else you get the reading and the history, not a verdict — because nobody here has calibrated those rivers.
- It won’t name small water. Named rivers and public ramps, yes. Working out where a photo was taken, no.
- Nothing is kept. No account, no cookie, no record of what you asked. Close the tab and it’s gone.
- It can be wrong. For seasons, closures and hoot-owl rules, ask the state agency — not this page.
