Best time of year: this gauge typically runs highest from early May to early August, peaking in June.
How we calculate this
This is a transparent outlook, not a precise forecast. We take the waterfall's current flow strength (how it ranks against its historical normal for today, from the nearest WSC stream gauge), carry that ranking forward along the gauge's seasonal curve, and nudge it for forecast rain. Confidence is highest for the next day or two and falls further out. Always check official conditions and your own judgment before visiting — high flows can be dangerous.
Know before you go
A waterfall on a dry week can be a disappointing trickle; the same fall after snowmelt or a good rain can be thundering. This tool reads the nearest stream gauge to tell you how a waterfall is running right now relative to its own normal, projects that strength across the next seven days, and points you to the best day to go. It also shows the time of year each waterfall typically peaks, so you can plan a trip months ahead.
Frequently asked questions
What is a waterfall flow forecast?
It's a 7-day outlook for how strongly a waterfall is likely to be flowing, plus the time of year it typically runs highest. We base it on the nearest USGS or Water Survey of Canada stream gauge, the gauge's seasonal pattern, and the rain in the weather forecast.
How accurate is the forecast?
It's a transparent, directional outlook — not a precise hydrological prediction. It's anchored on the live gauge reading (how the stream ranks against normal for today) and carried forward along its seasonal curve, then nudged for forecast rain. Confidence is highest for the next day or two and lower further out. Always check official conditions before you go; high flows can be dangerous.
When is the best time to see a waterfall?
Most waterfalls run highest in spring, fed by snowmelt and seasonal rain, and drop through late summer. The exact window varies by watershed — the tool shows each gauge's typical peak so you can plan around it.
Which waterfalls have a flow forecast?
Any waterfall close enough to a USGS (US) or Water Survey of Canada gauge to be matched to it. Search above — if a waterfall isn't listed, we don't have a nearby gauge for it yet.
