About Ellenor Brook at Size Bridge, Tyldesley
Ellenor Brook at Size Bridge, Tyldesley is a gauged river in England.
The watershed
For this station, the useful story is the short record and the seasonal shape. The gauge has 11 years on record, so patterns here are real but still fairly recent in hydrologic terms. Water Survey-style context is not available on this page; the station is published by the Environment Agency.
Temperate hydrology usually means higher water in the cool season and lower water in summer, and this gauge follows that broad pattern only in part. The highest typical month is December at 0.19 m (0.61 ft). The lowest typical month is June at 0.1 m (0.33 ft). That is a typical annual swing of 8.6 cm (3.4 in), which is small enough that small changes can matter for a shallow crossing, a bank edge, or a garden intake.
What the numbers say
The record high is 0.77 m (2.53 ft), reached in June 2023. The record low is 0.07 m (0.21 ft), reached in July 2018. Those two marks show the range this brook can cover over time, and they give a practical sense of what the gauge can throw at a local setup.
For people living nearby, the important point is that the brook can sit close to its low-water range in summer, then move up to much higher levels in a wet month or event year. For anglers, that means access and edge conditions can change quickly even when the brook is usually modest. For anyone with a low crossing, culvert, or pump intake, the gap between 0.07 m (0.21 ft) and 0.77 m (2.53 ft) is the kind of spread that can turn a routine day into a check-the-river day.
Reading the hero number
The hero number on this page should be read against the median level for this calendar day, not as a raw height on its own. That comparison matters because a level only becomes useful when you know whether it is ordinary for this date or unusual for the season.
With 11 years on record, the daily median gives a cleaner local reference than a single reading. The Environment Agency publishes the station, and the calendar-day comparison helps show whether Ellenor Brook is running near its usual state for the date, even when the absolute level looks small.
How this page is built
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.
How Nibi Metrics works · Water stories
Nibi Metrics - live water levels, flow, and forecasts for lakes and rivers across Canada, the US and the UK
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.
What you can see for any monitored lake or river
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.
Alerts that watch the water for you
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.
Where Nibi comes from
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.
Coverage
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.
Free forever, funded by members
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.
