Live river level, flow, historical records and forecast for River Derwent at Stamford Bridge in England, United Kingdom, built from official government gauge data.
River Derwent at Stamford Bridge is a gauged river in England.
The seasonal pattern here is narrow. January is the highest month in the record, with a typical level of 7.15 m (23.44 ft), while August is the lowest month, with a typical level of 7 m (22.97 ft). That gap is only 14.4 cm (5.7 in), so the river usually sits in a fairly tight band through the year.
For anyone drawing water, keeping a mooring, or watching the bank, that small swing means daily changes matter more than broad seasonal change. The river still has a highest month and a lowest month, but the spread between them is modest.
The highest level in the 28-year record is 9.9 m (32.46 ft), reached in November 2000. The lowest level in the same record is 6.78 m (22.23 ft), reached in April 2022. Those two marks show the range this reach has already covered.
For people living beside the river, that record range is the part worth remembering. A dock, intake, or low bank can see conditions that sit well above the usual seasonal band when the river is running near a record high, and well below it when the river is near a record low.
The hero number on this page is best read against the median level for the same calendar day across the station’s record, not as a raw height on its own. The Environment Agency uses that day-by-day comparison because a level that is ordinary in one season can be notable in another.
With more than 28 years on record, that context is useful for judging whether today is close to the middle of the station’s history for this date, or sitting well above or below it. That is more informative than the absolute reading alone for people deciding whether to check a bank, plan a crossing, or watch for a change in the river.
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.
