Live river level, flow, historical records and forecast for River Aire at Castleford in England, United Kingdom, built from official government gauge data.
River Aire at Castleford is a gauged river in England.
This station sits on the River Aire in England. With no watershed name provided here, the page has to stay with the reach itself and the way it behaves through the year.
For this river, the seasonal pattern is clear enough for planning. The highest typical month is December at 1.4 m (4.58 ft), and the lowest typical month is July at 1.13 m (3.69 ft). That annual spread is 27.1 cm (10.7 in). For a dock, a bank mooring, or an intake, that is the range to keep in mind rather than any single reading.
The record high is 3.18 m (10.44 ft), reached in December 2015. The record low is 0.55 m (1.79 ft), reached in May 2020. Those two marks show how far this river can move beyond its usual band when conditions push it.
The river’s strongest typical levels come in December, then ease back toward the July low. That fits temperate hydrology: higher water in the cooler months, lower water in summer.
What matters on the ground is the gap between the usual month-to-month level and the extremes. A river that sits around 1.4 m (4.58 ft) in its high month and 1.13 m (3.69 ft) in its low month can still reach 3.18 m (10.44 ft) in a major event. If you fish here, that is the difference between a familiar edge and a river that has moved well beyond it. If you keep gear near the bank, the record low of 0.55 m (1.79 ft) is the lower bound to remember.
The record set includes 30 years on record, so the seasonal pattern here is not a one-off snapshot. It is a useful guide for how the Aire usually behaves at Castleford.
The hero number on this page is today’s reading set against the median for the same calendar day across the station’s record. That is more useful than raw elevation because 1.4 m (4.58 ft) can mean something very different in December than it does in July.
With more than 30 years on record, the Environment Agency can place today’s level in a long local context. For anyone watching this river, that comparison tells you whether the water is ordinary for the date, running high, or sitting low for the season.
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.
