About Rivière Ashuapmushuan
Rivière Ashuapmushuan sits in the Ashuapmushuan watershed in Quebec.
The watershed
The station above this reach drains 15,515 km2 (5,990 sq mi) upstream of the gauge. That is the area feeding the reading here, not the whole watershed on a map. For people living along the river, that upstream area is what sets how much water can arrive after rain and snowmelt.
What the numbers say
The river’s record high is 27.78 m (91.14 ft) in May 2022; the record low is 23.64 m (77.56 ft) in March 2003. The typical high month is May at 26.05 m (85.47 ft), and the typical low month is March at 23.97 m (78.63 ft). That gives a typical annual swing of 2.09 m (6.8 ft).
That seasonal shape matters. Spring water can rise into May, so docks, ramps, and shoreline gear need to handle the upper part of the range. By late winter and early spring, levels tend to sit near the low end, which is the period when intakes and shallow launches are most exposed. The highest and lowest records are both useful markers: they show the outer edges of what this river has done here during the station record.
This station has 50 years on record, so the pattern is not a short one. The regional rhythm here is a strong spring freshet in April-May from snowmelt, summer low water, and early ice formation. The record does not give a fastest 24-hour rise, so there is no short warning-time figure to quote for this site.
Reading the hero number
The hero number on this page compares today’s reading with the median for this calendar day across the station’s record. That is more useful than raw elevation because it tells you whether the river is sitting near its usual level for this date or standing above or below it. For a gauge with 50 years of record, that day-of-year context is the cleanest way to judge what matters for boating, fishing, and shoreline use.
This station is operated by CEHQ.
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.
