Real-Time River Intelligence for the Northeast & Midwest
Stop guessing. StreamFlows translates raw USGS gauge data into clear, fishable-or-not conditions for 1,500+ rivers across the northeastern US and Midwest — so you know exactly where to go before you load the truck.
What's fishing right now
A quick look at conditions across some of the Northeast and Midwest's top fly fishing rivers. Updated every 15 minutes from live USGS gauges.
Deerfield River

Farmington River
Northern CT
Optimal: 180–400 CFS
Swift River
Central MA
Optimal: 80–200 CFS
Battenkill River
Southern VT
Optimal: 150–350 CFS
How StreamFlows works
We turn raw government gauge data into fishing intelligence you can act on in seconds.
Live USGS gauge data
We pull discharge, temperature, and gage height directly from USGS Water Services stations every 15 minutes.
River-specific thresholds
Each river has hand-tuned optimal flow ranges based on real fishing conditions — not generic defaults.
Actionable status labels
Raw CFS numbers become clear conditions: Optimal, Elevated, High, Low, or Ice-Affected. No interpretation needed.
Trends, history, and forecasts
See whether flows are rising, falling, or stable. 72-hour flow history and 5-day NOAA forecasts give you the full picture — spot the window before it opens, not after.
Built for how guides actually work
Every feature exists because someone needed it on the water — not because it looked good on a feature list.
Know what’s fishable right now
Every river shows a clear status — Optimal, Elevated, High, Low, or Ice-Affected. No more squinting at raw CFS numbers trying to decide if conditions are worth the drive.
Status is calculated from river-specific optimal ranges, not generic thresholds.
See where conditions are headed
Trend arrows and flow charts show whether a river is rising, falling, or holding steady. StreamFlows also layers in 5-day NOAA flow forecasts — so you can spot the window opening before anyone else does.
Short-range hourly and 5-day medium-range forecasts via the NOAA National Water Model, updated daily.
Build your river roster
Add your go-to rivers to a personal roster and see them all on one dashboard — flow, temp, trend, and status at a glance. No more juggling USGS bookmarks or checking five different pages before every trip.
Your roster syncs in real-time. Add backup rivers, track alert counts, and see upcoming trip context — all from the sidebar.
Plan client days with confidence
Create trip logs tied to specific rivers, track upcoming bookings, and let StreamFlows suggest backup rivers scored by current conditions. When flows shift near a trip date, you know before your client does.
The backup scorer ranks your roster rivers by status, trend, and proximity to your primary river.
Know what’s hatching
Per-river hatch calendars show what insects are emerging right now and what’s coming up next. Time your bookings around the Blue-Winged Olive emergence on the Farmington or the Sulphur hatch on the Battenkill.
Hatch data is editable — add your own observations and patterns as conditions change.
Get alerts when the river turns on
Set thresholds for optimal flow, specific CFS levels, or temperature targets. StreamFlows watches the gauges so you don’t have to.
Alerts trigger on real-time data checks every 15 minutes.
Keep private notes on every river
Record what worked, where you put in, which flies produced. Your notes stay private and attached to each river for next time.
Build a personal field guide that’s always connected to live conditions.
Built for people who take fishing seriously
Whether you're running trips or chasing your own fish, StreamFlows saves you time and puts you on better water.
For Guides
Make better decisions for your clients
- Check your entire roster at a glance before every client day
- See which rivers are fishing well now — and which will be in 5 days
- Plan trips with automatic backup river suggestions based on live conditions
- Track upcoming hatches to time bookings around peak fishing windows
- Get alerts when flow conditions change near a booked trip date
- Keep private notes on access points, patterns, and client preferences
For Serious Anglers
Stop guessing, start catching
- Track your favorite rivers in one dashboard instead of multiple USGS tabs
- Understand whether a river is fishable without interpreting raw CFS
- See flow trends so you can plan trips around rising or falling water
- Get notified when your home water hits the sweet spot
- Spend less time researching conditions and more time fishing
Why not just use USGS directly?
USGS provides great raw data. StreamFlows makes it useful for fishing.
Without StreamFlows
- Open multiple USGS pages for each river
- Interpret raw CFS numbers yourself
- Guess whether conditions are fishable
- No trend context — just a single snapshot
- Miss optimal windows because you weren’t checking
- No way to save rivers or take notes
With StreamFlows
- One dashboard for all 1,500+ rivers
- Clear status labels: Optimal, Elevated, High, Low
- Know instantly which rivers are fishing well
- Trend arrows and 24-hour charts show direction
- Alerts notify you the moment conditions change
- Roster, trip planner, hatch calendar, notes, and alerts — in one place
