Live river level, flow, historical records and forecast for Sandyford Brook at Astonfields in England, United Kingdom, built from official government gauge data.
Sandyford Brook at Astonfields is a gauged river in England.
January is the usual high-water month here, with a typical level of 0.27 m (0.88 ft). By August, the typical level is 0.16 m (0.51 ft). That is a modest seasonal swing of 11.4 cm (4.5 in), which matters most to anyone watching a low intake, a small bridge opening, or a bank-side mooring: the brook does move through the year, but not by a large amount on its typical pattern.
For a temperate river, that shape fits the calendar. Spring can run higher, while summer tends toward lower water. On this station, the seasonal range is still narrow enough that daily changes can be more relevant than the broad month-to-month pattern.
The highest level in the 21-year record was 1.13 m (3.69 ft) in October 2023. The lowest was 0.05 m (0.16 ft) in July 2010. Those two values show the reach can sit close to the bed in dry periods and still rise sharply at the top end when conditions are wet.
For local users, that spread is the main lesson. A dock, culvert, or small crossing that feels stable at the usual summer level may still need room for an autumn rise. Anglers will also notice that the river has shown a wide range over the record, even though its typical seasonal swing is much smaller.
The number on the page is the current reading from the Environment Agency, set beside the median for this calendar day across the station record. That comparison is more useful than raw elevation alone, because the same level can mean very different things in January and August.
At this site, the record spans more than 21 years, so the median gives a steady seasonal yardstick. It tells you whether today is running above or below what this brook usually carries for the date, which is the comparison most useful to cottagers, anglers, and flood-watchers.
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.
