Iskut River below Johnson River Water Level

Live river level, flow, historical records and forecast for Iskut River below Johnson River in Canada, BC, Canada, built from official government gauge data.

About Iskut River below Johnson River

The Iskut River below Johnson River is in the Iskut watershed in British Columbia.

The watershed

At this station, the drainage area above the gauge is 9,500 km2 (3,668 sq mi). That is the water that can reach this point before it passes the instrument, so it is the right scale for judging how quickly the river can respond to rain and snowmelt upstream.

In this part of BC, the seasonal pattern fits mountain hydrology: levels usually build toward early summer. The month with the highest typical level is June at 2.63 m (8.64 ft). The lowest typical month is March at 0.25 m (0.82 ft). The typical annual swing is 2.38 m (7.8 ft), which is the range a dock, pump intake, or crossing has to live with from one part of the year to the next.

What the numbers say

The record high is 5.97 m (19.58 ft), set in September 2011. The record low is -0.06 m (-0.18 ft), set in March 2023. Those two marks show that this river can sit near its seasonal low and still leave room for a large rise when conditions change.

No fastest 24-hour rise is listed here, so the page does not give a warning-time figure for a one-day jump. The seasonal numbers still tell the main story: expect the highest water in June and the lowest water in March, with a spread of 2.38 m (7.8 ft) across the year.

Reading the hero number

This page’s hero number is best read against the median for the same calendar day, not as a raw elevation. A river level by itself can look large or small without saying whether it is ordinary for this date. The median puts today beside the station’s own record for this day of year.

This station has more than 66 years on record, and the operating agency is Water Survey of Canada. That record length makes the daily median more useful than a single reading, because it shows whether the river is running above, below, or near its usual position for today.

How this page is built

Readings come from official government gauges and are rolled into daily records: the daily mean, high and low for every day on record. Each calendar day gets its own baseline from the full history, so the level you see is compared against what this specific date usually looks like rather than an annual average.

Nibi Metrics - live water levels, flow, and forecasts for 17,900+ lakes and rivers

Real-time water levels, forecasts, and alerts for lakes and rivers in a growing number of countries. Built on official government data.

Nibi Metrics tracks more than 17,900 gauged lakes and rivers in a growing number of countries, reading directly from official federal monitoring networks: the Water Survey of Canada, the United States Geological Survey, Quebec's provincial hydrometric network, the Environment Agency for England, the Scottish Environment Protection Agency, Natural Resources Wales, the Office of Public Works in Ireland (waterlevel.ie), the Norwegian Water Resources and Energy Directorate (NVE), the State of Queensland's water monitoring network, and on the Great Lakes the Canadian Hydrographic Service and NOAA. Every number on the platform is measured, not modelled - taken from a government gauge on the water itself and compared against that location's own historical record for this exact date.

What you can see for any monitored lake or river

The level right now, in feet or metres, updated as the source agency publishes new readings - for many stations that is every five to fifteen minutes. How today compares to typical: every location carries its own typical-for-this-date band built from its historical record, so a reading is never just a number - it is above, below, or near what this water usually does on this calendar day. Which way it is moving: a measured RISING, FALLING, or STEADY verdict computed from the gauge's own recent readings, with the rate of change - the difference between a flood ending and one beginning. What comes next: level forecasts up to 72 hours ahead, driven by the gauge's recent behaviour, upstream water, and quantitative precipitation forecasts, alongside live radar, lightning, and weather for the surrounding region.

Alerts that watch the water for you

Set a threshold on any location - a level, a distance above typical, or a rate of climb - and Nibi emails or notifies you the moment the gauge crosses it. Cottagers use it for spring freshet, anglers for river conditions, marinas and municipalities for operations. The scanning runs around the clock against the same measured data shown on every page.

Where Nibi comes from

Nibi means water in Anishinaabemowin. The platform began at a family cottage on Lake Muskoka, Ontario, where the spring melt floods the shoreline most years and the only forecast was standing on the dock, looking, and guessing. It grew into an independent, member-funded platform run by Muskoka Research Inc. - no investors, no data resale, and a privacy policy shorter than most cookie banners. The core data is free for everyone, forever; paid plans add automation like multi-location alerts, deep history, and reports.

Coverage

Nibi spans the continent: every Canadian province and territory with active federal gauges - from Vancouver Island rivers to the Muskoka lakes, prairie reservoirs, and Quebec's hydrometric network - and the United States from Maine to the Texas Hill Country, the Ohio Valley, and the Pacific Northwest. Coverage grows where the water news is: when a basin floods, its gauges join the platform with their full historical records attached. Many stations report every five to fifteen minutes; most report at least hourly; every page states exactly when its gauge last spoke.

Free forever, funded by members

The core promise is simple: the water data is free, for everyone, forever. Live levels, maps, radar, and recent history never sit behind a paywall. Paid plans fund the platform by adding automation - multi-location alerts, decades of history, longer forecasts, and PDF reports - so the people who need more carry the cost for everyone who just needs to check the lake before driving up. There are no investors and no advertising deals shaping what the data says.

Water Stories

Field notes and explainers from the Nibi desk - how to read a staff gauge, what a 100-year flood actually means, how snowpack becomes summer water.

The lake that did not rise 117 metres

The largest lake in Norway read under 8 metres for decades and reads over 120 today. The water did not move; the ruler did. What the zero of a gauge is, why a record only means something on one reference, and what we do when the zero moves.

The flood that came on a clear day

There was no rain. A slab of glacier let go above the Trishuli, and a river gauge reading normal at 8:40 was silent by 8:50. What a river network can see coming, what it cannot, and what warning has to look like when the water outruns the news.

The flood of record that was overtaken

For five years, spring 2019 was the mark every Lake Muskoka decision answered to. In April 2026 the lake went two centimeters higher - and the official books have not caught up yet.
