Live river level, flow, historical records and forecast for Aylesbury Thame in England, United Kingdom, built from official government gauge data.
Aylesbury Thame is a gauged river in England.
This station sits on the River Thame reach at Aylesbury Thame, and the record here spans more than 39 years. For people watching this water day to day, that is enough time to show the river’s regular range and its outliers.
The seasonal pattern is modest but clear. The highest typical month is January at 0.88 m (2.9 ft), and the lowest typical month is April at 0.68 m (2.23 ft). The typical annual swing is 20.4 cm (8 in), so docks, small intakes, and low banks here need to handle change, but not large change.
The record high is 2.53 m (8.3 ft), reached in October 2020. That is the kind of level that tells a local user to pay attention to access, bank clearance, and anything left close to the waterline.
The record low is -0.01 m (-0.05 ft), reached in July 2026. Low water here is part of the station’s range, and it matters most for shallow launches, fish holding water, and any intake that depends on depth.
The seasonal rhythm fits a temperate river: higher water in winter, lower water in spring. Here, the month-to-month change is not large, but it is enough to matter when you use the river regularly.
The number shown on this page is the current reading, set against the median for the same calendar day across the station’s record. That comparison is better than raw elevation because it shows whether the river is running high or low for this date, not just where it sits above a fixed datum.
At Aylesbury Thame, that context is especially useful because the river’s ordinary swing is small. Water Survey of Canada-style station logic does not apply here; this page is published from EA data, so the operating agency is the Environment Agency.
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.
