About River Mole at Leatherhead
River Mole at Leatherhead is a gauged river in England.
The watershed
This station sits on the River Mole in England, and the record here spans more than 40 years. That is enough to show a reach with a clear seasonal pattern and a wide spread between ordinary days and extremes.
For people watching a bank, dock, or intake, the seasonal swing matters most in day-to-day use. The typical annual swing is 29.7 cm (11.7 in), which is small enough to miss by eye on some days, but it still changes how much clearance or freeboard you have. The river’s typical high month is August at 1.39 m (4.56 ft), while the typical low month is October at 1.09 m (3.59 ft). In this reach, late summer and early autumn are the months to watch most closely for lower water.
What the numbers say
The record high is 3.04 m (9.98 ft) in December 2013. The record low is 0.89 m (2.91 ft) in February 1991. Those two marks show the range this river has already reached at the gauge, and they are the best reminders that a familiar channel can still move well outside its usual band.
For anyone drawing water, fishing the margins, or planning work near the bank, the useful point is not the peak alone but the spread between the usual month and the record range. The river’s normal swing is modest, yet the historical extremes are much larger. That is the difference between an ordinary level and a level that demands a change in plans.
Reading the hero number
The hero number on this page is today’s reading set against the median for this calendar day across the station record. That is more useful than raw elevation because a single level means little without the river’s normal range for this date.
At this station, the reader is looking through a record of more than 40 years at the Environment Agency gauge. The comparison to the day-of-year median tells you whether today is running high or low for this time of year, which is what matters for access, fishing conditions, and short-term decisions along the river.
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.
