About River Irwell at Holt Mill Bridge
River Irwell at Holt Mill Bridge is a gauged river in England.
The watershed
This station has 16 years of record from the Environment Agency. The river’s level here is seasonal, with the highest typical month in December at 0.25 m (0.83 ft) and the lowest typical month in July at 0.14 m (0.44 ft). That gap is 11.7 cm (4.6 in), which is modest on paper but still enough to matter for bankside access, shallow crossings, and any setup that needs a steady edge.
The record high is 0.86 m (2.82 ft) in October 2017. The record low is -0.27 m (-0.89 ft) in April 2023. Those two marks frame the range this gauge has already seen, and they are worth keeping in mind when the river moves outside its usual winter-to-summer pattern.
For cottagers and anglers, the main takeaway is simple: expect the river to run higher in the colder part of the year and lower in July. If you are watching a bank, a mooring, or a fishing position, the seasonal swing is the number that tells you how much change is normal before a reading starts to look unusual.
What the numbers say
The river’s highest typical month is December, not spring. Its lowest typical month is July, which fits the summer low-water pattern in temperate hydrology. The record low in April 2023 sits well below that seasonal low, so this gauge has already shown a sharper drop than the usual summer pattern suggests.
The record high in October 2017 is also a useful reminder that the biggest water on this river does not have to wait for midwinter. When levels climb into that range, low banks and near-channel ground are the first places to notice.
Reading the hero number
The hero number on this page is today’s reading compared with the median for this calendar day across the station’s record. That is more useful than raw elevation alone, because 0.20 m (0.66 ft) can mean very different things in December and in July.
On a river with 16 years of record, that day-by-day comparison helps you judge whether the river is sitting near its usual level, above it, or below it for this date. For anyone checking access, fishing conditions, or shoreline clearance, that context is the part that matters.
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.
