Live river level, flow, historical records and forecast for River Mersey at Fiddlers Ferry in England, United Kingdom, built from official government gauge data.
River Mersey at Fiddlers Ferry is a gauged river in England.
This station has 22 years on record, enough to show a clear seasonal range as well as a few extremes.
The highest level in the record is 5.09 m (16.7 ft) in March 2006. That is the upper end of what this reach has carried, and it matters for anyone with low banks, moorings, or infrastructure close to the waterline.
The lowest level in the record is 1.5 m (4.92 ft) in April 2023. That is the dry-end reference point for this gauge, useful for setting expectations around shallow margins, intakes, and launching conditions.
Seasonally, the highest month is October at 3.71 m (12.17 ft), while the lowest month is June at 3.36 m (11.02 ft). The typical annual swing is 35 cm (13.8 in). That is not a large spread, but it still tells you the river is not flat through the year: the autumn level sits above early summer, so the reach tends to ask a little more of docks and bank access later in the season.
The regional pattern here is familiar temperate hydrology: spring peaks are often tied to snowmelt or rainfall, and summer water tends to ease off. On this gauge, the monthly record runs a little differently from that simple rule, with October as the higher month and June the lower one.
For users on the river, that means the local rhythm is worth watching more than the calendar stereotype. If you are managing a bank, a pump, or a landing spot, the October-to-June difference is the seasonal span the river has already shown at this station.
The hero number on this page is best read against the median for the same calendar day, not as a raw level on its own. A single elevation can look high or low without context; the daily median tells you where today sits within this station’s own record.
This station is published by the Environment Agency, and the 22-year archive gives that comparison enough local history to be useful. For day-to-day decisions, that is the figure that matters: it shows whether the river is running near its usual level for this date, or whether it is leaning well above or below it.
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.
