About Roseberry River above Roseberry Lakes
What the record shows
Roseberry River above Roseberry Lakes sits in the Upper Severn watershed in Ontario.
This station has more than 58 years of record. The highest level on file is 32.56 m (106.81 ft), set in May 2022. The lowest is 29.47 m (96.68 ft), set in October 2024. That span tells you the river can move through a wide range, so a dock, crossing, or intake here has to tolerate more than a small shift.
The seasonal pattern is clear. The typical high month is May at 30.5 m (100.06 ft), while the typical low month is March at 29.65 m (97.27 ft). The typical annual swing is 84.9 cm (33.4 in). For someone living or fishing here, that means water is usually highest in spring and lowest near the end of winter, with enough movement to change shore access and the depth at a landing.
The regional rhythm fits the record: spring freshet late April-May, then natural summer drawdown July-September, with early-winter decline as ice forms.
The watershed
The gauge drains 624 km2 (241 sq mi) above the station. That is the area feeding this reading, not the whole Upper Severn watershed.
For cottagers and anglers, the main point is simple: this is a medium-sized upstream area, so local rain and snowmelt can show up at the gauge without much delay. The record also shows that low water is not limited to one month, and the river can still reach its high marks well outside the usual seasonal peak.
Reading the hero number
The hero number on this page should be read against the median for this calendar day, not as a raw elevation in isolation. A level by itself can look high or low, but the day-of-year median shows whether today is typical for this station’s season.
That matters here because the river has a strong annual swing and a long record from the Water Survey of Canada. With more than 58 years on record, the daily median gives a better quick check on whether today sits above, near, or below the usual pattern for this date.
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.
How Nibi Metrics works · Water stories
Nibi Metrics - live water levels, flow, and forecasts for lakes and rivers across Canada, the US and the UK
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.
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.
