Live river level, flow, historical records and forecast for River Poulter at Twyford Bridge in England, United Kingdom, built from official government gauge data.
River Poulter at Twyford Bridge is a gauged river in England.
The seasonal pattern here is modest but clear. June is the typical high-water month at 0.89 m (2.92 ft), while April is the typical low-water month at 0.54 m (1.78 ft). That spread is the kind of difference a bank-side intake, low bridge, or fishing spot has to live with from spring into early summer.
The typical annual swing is 34.6 cm (13.6 in), so daily changes are usually measured in centimetres rather than metres. For people using the river regularly, that means conditions can shift enough to matter without becoming extreme.
The station record spans about 50 years, and the range of water levels shows what this reach can do. The record high was 2.65 m (8.69 ft) in October 2023. The record low was 0.16 m (0.52 ft) in September 1976.
Those are useful bounds for anyone watching the river. The high record tells you the top end this gauge has seen in its record; the low record shows how far levels can fall in a dry spell. Read together, they set the context for both flood watch and low-water planning.
The hero number on this page is best read against the median for this calendar day from the station record, not as a raw height on its own. A level by itself says little unless you know whether this date is usually above or below centre for the year.
This gauge is run by the Environment Agency. With about 50 years on record, the station gives a long enough history to compare today’s reading with the normal pattern for the same day, which is more useful than elevation alone when you are deciding whether to check a mooring, an intake, or a favourite fishing stretch.
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 in a growing number of countries. Built on official government data.
Nibi Metrics tracks more than 19,410 gauged lakes and rivers in a growing number of countries, reading directly from official federal monitoring networks: the Water Survey of Canada, the United States Geological Survey, Quebec's provincial hydrometric network, the Environment Agency for England, the Scottish Environment Protection Agency, Natural Resources Wales, the Office of Public Works in Ireland (waterlevel.ie), the Norwegian Water Resources and Energy Directorate (NVE), the State of Queensland's, the State of Victoria's, the State of South Australia's, the Northern Territory's and the State of Western Australia's water monitoring networks, the French State's hydrometric network (Vigicrues, through Hub'Eau), the German Federal Waterways and Shipping Administration's gauges (WSV, through PEGELONLINE), and on the Great Lakes the Canadian Hydrographic Service and NOAA. 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.
Field notes and explainers from the Nibi desk - how to read a staff gauge, what a 100-year flood actually means, how snowpack becomes summer water.
The largest lake in Norway read under 8 metres for decades and reads over 120 today. The water did not move; the ruler did. What the zero of a gauge is, why a record only means something on one reference, and what we do when the zero moves.
There was no rain. A slab of glacier let go above the Trishuli, and a river gauge reading normal at 8:40 was silent by 8:50. What a river network can see coming, what it cannot, and what warning has to look like when the water outruns the news.
For five years, spring 2019 was the mark every Lake Muskoka decision answered to. In April 2026 the lake went two centimeters higher - and the official books have not caught up yet.
