Finding the top signal on the water…
Live river level, flow, historical records and forecast for Henderson Creek near Oquawka in IL, United States, built from official government gauge data.
Henderson Creek in the Flint-Henderson watershed of Illinois is monitored near Oquawka.
The creek usually runs highest in May at 15.78 ft (4.81 m) and lowest in October at 12.87 ft (3.92 m). That spread is 34.9 in (88.7 cm) across the typical year, which matters for docks, crossings, and any intake set close to the bank.
For people living or working along the creek, that seasonal shape means spring is the time to watch for higher water, while late summer and fall are more often the season of lower stages. If you fish here, the difference between those months changes access, bank cover, and where the deeper edge sits.
The record high is 28.71 ft (8.75 m) in April 2013. The record low is 11.48 ft (3.5 m) in October 1994.
Those two marks show the range this creek has carried over the record. The high water was well above the typical May level, so anyone with low ground near the channel would have had little margin. The low water was below the usual October level, which is the kind of stage that can leave shallow crossings and shore fishing spots harder to use.
The station has 50 years on record, which is enough history to separate an ordinary rise or fall from something outside the usual pattern.
The hero number on this page is today’s reading, set against the median for this calendar day across the station record. That is more useful than raw elevation because a stage of one height can mean very different things in May than it does in October.
This station is run by the USGS. With 50 years on record, the median gives a practical baseline for cottagers, anglers, and flood-watchers: it tells you whether the creek is running near its usual place for this date, not just how high it sits above sea level.
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.
