Live river level, flow, historical records and forecast for Beverley Brook at Wimbledon Common in England, United Kingdom, built from official government gauge data.
Beverley Brook at Wimbledon Common is a gauged river in England.
The brook’s typical high point comes in January at 0.26 m (0.85 ft), while September is the typical low month at 0.21 m (0.67 ft). That is a small seasonal swing of 5.4 cm (2.1 in), so the day-to-day changes are modest compared with many rivers. For anyone with a crossing, outfall, or shallow edge to watch, the practical message is that this reach usually shifts within a narrow band through the year.
Temperate hydrology often brings higher water in the cooler months and lower water in late summer, and this station fits that pattern. The seasonal range here is not large, but it is enough to matter for low banks, marginal habitat, and any fixed point that sits close to the waterline.
The highest level in the record is 1.08 m (3.53 ft), set in July 2007. The lowest is 0.08 m (0.25 ft), set in July 2008. Those two July marks show how wide the brook can move when conditions change. For local users, that means the same reach has already shown both a high summer crest and a very low summer level.
The station has 42 years of record, so these extremes are not one-off snapshots. They sit within a long enough archive to show the brook’s range clearly, which is more useful than a single day’s reading when you are judging how much room the water has left to move.
The hero number on this page is best read against the median for the same calendar day across the station’s record, not just as an absolute level. A level in metres or feet tells you where the water stands right now; the day-specific median tells you whether it is running above or below the usual position for this date.
That comparison is the one the Environment Agency uses here. With more than 42 years of record behind it, the daily median gives context that raw elevation cannot: it shows whether today is ordinary for the season or shifted away from the centre of the brook’s usual range.
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.
