Season by season
The yearly pattern here is set by the warm season and the dry season. In this region, June through September is the window when convective storms and tropical systems usually push water up, while winter and spring tend to bring the lower flows. On flat ground, water can hang around after a rise, so a change upstream may stay visible for days.
The station’s typical high month is October at 17.13 ft (5.22 m), which tells you that late-season water can sit near the top of its usual range. The typical low month is May at 15.54 ft (4.74 m), so docks, pumps, and any low-lying crossing have to tolerate a noticeable spread between the dry-season low and the wetter part of the year. The typical annual swing is 19.1 in (48.5 cm), which is enough to matter for fixed structures even when the water is not in record territory.
Records and rises
The record high is 18.18 ft (5.54 m) in October 1999. For a local user, that is the upper edge of what this reach has shown in the record, not just a seasonal bump.
The record low is 12.23 ft (3.73 m) in May 2001. That low is a reminder that this site can fall well below its wetter-season levels, so shallow access and intake setup need room for decline as well as rise.
With 35 years on record, these extremes sit in a useful span of history. They give a practical sense of what the water has already done here, which is more useful than a single day’s number by itself.
Reading the hero number
The hero reading on this page is compared with the median for the same calendar day across the station’s record. That is better than raw elevation because it shows whether today is ordinary for this date, high for the season, or running low.
At this USGS station, the comparison is grounded in more than 35 years of record, so the page is not just showing height in isolation. It is showing where the river sits relative to its own history, which is the figure that matters most for access, flooding, and day-to-day use.
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.
