About Whetstone Brook at Whetstone
Whetstone Brook at Whetstone is a gauged river in England.
The watershed
This station sits on Whetstone Brook in England, with no watershed name given here, so the useful view is the reach itself and its season to season movement. For people using the brook, the main pattern is modest but real: the typical level is highest in January at 0.21 m (0.69 ft) and lowest in August at 0.11 m (0.37 ft). That is a typical annual swing of 9.8 cm (3.9 in), which is enough to matter for shallow margins, small intakes, and the waterline on low banks.
The record range shows that the brook can move beyond that seasonal band. The highest level in the record is 0.84 m (2.77 ft) in December 2019, while the lowest is -0.04 m (-0.12 ft) in July 2025. For anyone watching access, wading depth, or bank exposure, those two dates show the reach can fall well below its usual summer level and also rise well above its usual winter pattern.
What the numbers say
The seasonal rhythm fits temperate hydrology: higher water in winter and lower water in late summer. The month-to-month change is not large in the average year, but the record low and record high show why a single day can still matter.
With 24 years on record, the station gives enough history to see that January is the usual high point and August the usual low point. That makes the brook useful for comparing this week’s water level with what is normal for the same time of year, rather than with an absolute number alone.
Reading the hero number
The hero number is most useful when it is compared with the median for the same calendar day across the station record, not just with the raw water level. A raw level by itself does not tell you whether the brook is running high for this date or simply following its usual pattern.
This station is operated by the Environment Agency. With more than 24 years on record, the day-median gives a cleaner read on whether today sits above or below the usual range for this date, which is the part that matters for cottagers, anglers, and anyone watching the brook closely.
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.
