Finding the top signal on the water…
Live river level, flow, historical records and forecast for South Bay Diversion Channel at South Bay in MB, Canada, built from official government gauge data.
South Bay Diversion Channel at South Bay sits in the Southern Indian Lake watershed in Manitoba.
The station drains 259200 km2 (100078 sq mi) upstream of this gauge. That is the area contributing water to the channel at this point, not the whole watershed on a map.
For people on the water, the useful pattern is the range between the typical low and high months. The typical level is 257.42 m (844.55 ft) in April and 258.06 m (846.66 ft) in October, for a typical annual swing of 64.1 cm (25.2 in). That is the band a dock, intake, or landing has to live with through the year.
The highest level in the record is 258.54 m (848.23 ft) in May 2017. The lowest is 256.87 m (842.74 ft) in May 2002. Over 47 years on record, those two marks frame how far this water can move at this station.
The seasonal pattern is not a spring crest here. The typical high month is October, and the typical low month is April. That is the main clue for anyone checking shore access, mooring height, or a pump setting: the channel’s usual rise and fall is modest, but it still changes enough to matter at fixed points.
No fastest 24-hour rise is available in the facts for this station, so there is nothing to add there.
The hero number on this page is today’s reading against the median for this calendar day across the station record. That is more useful than raw elevation because it tells you whether the channel is running high or low for this date, not just how many metres above sea level it sits.
With 47 years on record, that day-by-day comparison gives a better read on what matters for access, pumping, and shoreline use.
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.
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.
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.
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.
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.
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.
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.
