About Seven Persons Creek at Medicine Hat
Seven Persons Creek is in the Seven Persons watershed in Alberta.
Season by season
The typical annual swing is 27.3 cm (10.7 in), which is enough to matter for a low dock, a shallow intake, or a riffle that can turn thin or slack. The usual high point comes in August at 0.7 m (2.31 ft), while the usual low point comes in January at 0.43 m (1.41 ft).
That seasonal shape is not the whole story. In this foothills and prairie setting, late spring can still be the season to watch, and summer storms can push the creek up fast. For anyone working or fishing near the channel, the range from winter low to late-summer high is the baseline, but short rises can move conditions outside that baseline quickly.
Records and rises
The record high is 1.68 m (5.52 ft), set in February 2025. The record low is 0.31 m (1.02 ft), set in February 2021. Those two readings show how far the creek can move beyond its usual seasonal range.
The fastest 24-hour rise on record is 48.3 cm (19 in), in April 2018. The fastest 24-hour drop is 24.2 cm (9.5 in), in April 2023. For local users, that rise is the practical warning time: a day can be enough for water to change from easy to awkward at a crossing, along a bank, or at a pump.
The station’s upstream drainage area is 3680 km2 (1421 sq mi), so changes upstream can show up here over a broad catchment.
Reading the hero number
This page’s hero number is today’s reading compared with the median for this calendar day across the station record. That is more useful than raw elevation because a level only becomes meaningful when you know what is normal for this date.
With 49 years on record, Water Survey of Canada is the agency behind the reference series here.
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.
