For anglers who read the river
Fish when the river says go.
Set the flow and temperature you like to fish, and Riverbot emails you the moment a station hits it. It reads public river gauges every 15 minutes so you don't have to.
For anglers who read the river
Set the flow and temperature you like to fish, and Riverbot emails you the moment a station hits it. It reads public river gauges every 15 minutes so you don't have to.
Everything below is running today — no waitlist, no beta.
Browse 11,000+ gauges on a live map, with rivers highlighted. Click any station for a live flow reading, or let Riverbot find the gauges near you.
Canadian WSC gauges and US USGS gauges, side by side. Pick cfs or m³/s in your profile and every reading follows.
Set min and max flow and water temperature per station. Leave a field blank to ignore it.
You hear from us when the window opens or closes — not every reading. A one-hour cooldown kills the noise.
See predicted daily flow for the week ahead, with good-window days flagged against the thresholds you set.
Flow and temperature come straight from North America's public river-monitoring networks, checked every 15 minutes.
On rivers we have data for, sign in to see what's hatching this month — insect, hook size and patterns to fish — from fly shops and guides who know the water. Month by month, all year.
Native apps for iPhone and Apple Watch, built on the same live data as the web app. In private beta now. Create an account and use the web app today.
Sign in (2FA and all), search every gauge, and set your flow and temperature windows from your pocket. Flow and temperature history charts, the 7-day outlook, favourites and push alerts — the web app, native.
Your favourite stations on your wrist — current flow, water temperature and a 7-day flow chart, at a glance. It syncs your session from the iPhone, so there's nothing to sign into on the watch.
Pin one station's flow and temperature right on your watch face — rectangular, circular, corner or inline. It refreshes through the day and always shows how fresh the reading is.
Choose a river and gauge from 11,000+ real-time stations across Canada and the US.
Enter the flow and temperature that fish for you.
We watch the gauge and email you when it lands in range.
In backtesting on station 02GA016, the 7-day flow model lands at a mean absolute error of 2.014 m³/s against 2.261 for a naive “same as today” guess — about 11% better on a dam-regulated river.
Days 5 to 7 compound error, so read them as a trend, not gospel. Every forecast in the app carries these numbers with it.
Planned, not shipped. Listed here so you know what you're not getting yet.
Most countries publish open gauge data. North America first; the map doesn't end there.
US water temperature is broadly live via USGS. On the Canadian side it's still Grand River watershed only — we're mapping more gauges.
Sensible flow and temp defaults to start from, tuned per fish. Tweak from there.
Today's hatch calendars are month-by-month reference from fly shops. Next: predicting emergence from the water temperature we already record, so a warm spring moves the date instead of the chart being wrong.
Hatch data covers a few hundred rivers so far, weighted to the US. More sources, and more Canadian water, are next.
A heavier prediction model and true upstream-catchment rainfall are in the plan.
We'd alert on clarity too, if a public turbidity feed existed. Still looking.
Tell Riverbot the conditions you fish, and let it watch the river for you.
