Nibi Metrics - live water levels, flow, and forecasts for lakes and rivers across Canada and the US
Real-time water levels, forecasts, and alerts for lakes and rivers across Canada and the US. Built on official government data.
Nibi Metrics tracks more than 13,000 gauged lakes and rivers across Canada and the United States, reading directly from official federal monitoring networks: the Water Survey of Canada, the United States Geological Survey, and Quebec's provincial hydrometric network. 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.

About Black River at Poplar Bluff
Black River at Poplar Bluff - A vital waterway in the Ozarks.
The Black River at Poplar Bluff is a significant tributary within the Upper Black River watershed in Missouri. Known for its flowing waters and important ecological role, this river is integral not just to its immediate environment but also to the communities that depend on it for recreation and water resources.
The watershed context
Draining an impressive 1,245 square miles above the station, the Black River at Poplar Bluff serves a vast catchment area that contributes to its flow. The river flows through a landscape shaped by Ozark hydrology, which is primarily influenced by rainfall. This hydrology can lead to rapid flooding occurrences, particularly during the spring months when rainfall is most abundant. The interplay of rainfall and local karst springs helps sustain the base flows of the river throughout the year, balancing natural cycles and supporting local ecosystems.
The river connects with several peers, including the Black River near Annapolis and the Clearwater Tailwater near Piedmont, providing essential linkages within the hydrological landscape of the region. This connectivity is crucial for maintaining the river’s health and the diverse habitats found along its banks.
Why the data matters here
Understanding the water levels of the Black River at Poplar Bluff is essential for local users who may be engaged in fishing, boating, or agricultural activities. Monitoring water levels, especially in relation to historical data, helps manage and predict flood events, ensuring safety for both residents and recreational enthusiasts.
At present, the river's hydrological data is sourced from the U.S. Geological Survey (USGS). Today’s reading of the Black River at Poplar Bluff is compared against the median for this calendar day across the station's historical record, which spans over 50 years. This comparison is vital, as it provides a context for evaluating the current conditions of the river beyond mere raw elevation measurements, aiding in making informed decisions about water use and flood preparedness.
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.
