Live river level, flow, historical records and forecast for River Mole at Dorking in England, United Kingdom, built from official government gauge data.
River Mole at Dorking is a gauged river in England.
This station has 49 years on record.
The highest level in the record is 1.78 m (5.85 ft), set in November 2000. The lowest is 0.05 m (0.18 ft), set in September 2011. That range tells you the river can move from very thin flow to levels that sit far higher on the gauge.
The seasonal pattern is fairly regular. January is the highest typical month at 0.24 m (0.8 ft), while September is the lowest typical month at 0.1 m (0.34 ft). The typical annual swing is 14 cm (5.5 in). For cottagers and anyone with an intake or low bank access, that is the part of the record to watch: winter water sits higher, and late-summer water sits lower.
No watershed name is given for this page, so the gauge itself is the right frame of reference. What matters here is the reach at Dorking and its seasonal rhythm.
In temperate hydrology, rivers like this usually rise through the wetter half of the year and ease back in summer. The record here fits that pattern in broad terms, with January the typical high month and September the typical low month. For anglers, that usually means more water to work with in winter and tighter, shallower conditions later in the season.
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 alone, because a level means more when you know what is normal for this date.
The station is operated by the Environment Agency. With 49 years on record, that comparison gives a practical read on whether today is running above or below the usual seasonal mark at Dorking.
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.
