Live river level, flow, historical records and forecast for North Canadian River at Shawnee in OK, United States, built from official government gauge data.
North Canadian River at Shawnee is in the Lower North Canadian watershed, Oklahoma.
The station has 25 years on record. The high-water mark is 23.37 ft (7.12 m), reached in May 2015. The low-water mark is 7.85 ft (2.39 m), reached in August 2012.
The seasonal pattern is modest but real. Typical level is highest in May at 10.52 ft (3.21 m) and lowest in October at 9.33 ft (2.84 m). That typical annual swing is 14.3 in (36.2 cm).
For people using the river, that means the range from a spring high to an autumn low is not huge in the usual year, but the record spread shows the river can move well beyond its typical band.
The gauge drains 14,005 sq mi (36,273 km2) upstream of the station. That is the area feeding this reading, not the whole named watershed.
In southern-plains weather, spring is the main storm season, and the river’s record and seasonal pattern fit a reach that can rise quickly and then spend long stretches easing back. The numbers here do not show a large seasonal climb every year; they show a river that sits in a fairly tight typical band, then can jump well outside it when conditions line up.
For cottagers, anglers, and anyone with a low crossing or intake nearby, the useful point is that a modest-looking stage change can still matter when the river is already near the edges of its usual May-to-October range.
The hero number on this page should be read against the median for this calendar day, not as a raw height by itself. That is the better check because stage changes through the year, and a number that looks ordinary in one season can be high or low for another.
This station is a USGS site, and the comparison is built from more than 25 years of record. If you are watching for access, bank stress, or a changing current, the median-for-today view is the one that tells you whether the river is running above or below its usual level for this date.
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.
Real-time water levels, forecasts, and alerts for lakes and rivers across Canada, the US and the UK. Built on official government data.
Nibi Metrics tracks more than 13,000 gauged lakes and rivers across Canada, the United States and the United Kingdom, reading directly from official federal monitoring networks: the Water Survey of Canada, the United States Geological Survey, Quebec's provincial hydrometric network, and the Environment Agency for England. 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.
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.
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.
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.
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.
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.
