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 Onion Creek at Us Highway 183, Austin
Onion Creek - a vital waterway in Austin's busy landscape.
Onion Creek, located at US Highway 183 in Austin, Texas, serves as an important conduit for rainwater within the vibrant Austin-Travis Lakes watershed. This creek provides a crucial resource for both the local ecosystem and the community, making it a significant part of the urban fabric of Austin.
The watershed context
The Austin-Travis Lakes watershed is characterized by rapid, rainfall-driven responses, especially during significant precipitation events. The hydrology in this region often leads to flash floods, with water levels rising dramatically within hours rather than days. Conversely, during prolonged dry spells, the creek can experience long stretches of low flow, highlighting the stark contrasts in Texas's water regime. The surrounding waterways, including Barton Creek and Bear Creek, can also experience similar patterns, collectively influencing the region's water management and ecological health.
Onion Creek is served by a sizable drainage area of approximately 321 square miles, which collects runoff from surrounding landscapes, feeding into the creek. The interplay between urban development and natural waterways is ever-present in Austin, making the monitoring of Onion Creek particularly important for flood safety and water availability.
Why the data matters here
Data from the US Geological Survey (USGS) station monitoring Onion Creek is essential for understanding the current conditions of this dynamic waterway. Today's reading, compared against the median for this calendar day over more than 50 years, provides context critical for both local residents and decision-makers. By evaluating the current water level alongside historical data, stakeholders can better anticipate and respond to flood risks and water shortages.
This analytical approach goes beyond mere elevation readings; by comparing to historical medians, it allows for a nuanced understanding of where today’s conditions stand relative to typical patterns, ensuring informed choices can be made regarding public safety and resource management.
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.
