Live river level, flow, historical records and forecast for Bridge of Teith in Scotland, United Kingdom, built from official government gauge data.
Bridge of Teith is a gauged river in Scotland.
This station has 34 years on record, so the range it has seen is worth paying attention to.
The high-water mark is 2.63 m (8.62 ft) in December 2015. The low-water mark is 0.37 m (1.21 ft) in September 1993. For anyone using a dock, intake, or riverside access, those two points show that this reach can move a long way between dry spells and major rain events.
Seasonally, January is the highest month at 0.98 m (3.21 ft), while July is the lowest month at 0.6 m (1.98 ft). That pattern fits a rain-driven river in this part of the world: winter and early spring are usually the period to watch for higher water, while warm-season low water can hold for longer.
The typical annual swing is 37.6 cm (14.8 in). That is the scale of change a shore setup, mooring line, or shallow crossing needs to tolerate through the year.
The station drains 518 km2 (200 sq mi) upstream of the gauge. That is the area feeding this reading, not a broader estimate of the whole river system.
For local users, the size of that upstream area matters because rain over that ground can reach the gauge in a short window during wet periods. On a river with this catchment, fast rises are a practical concern after prolonged rain, and lower summer water can affect shallow access and bank margins.
SEPA is the operating agency behind this station, so the level you see here is the official gauge record for this reach.
The hero number on this page compares today’s reading with the median for this calendar day across the station’s record. That is more useful than raw elevation alone, because it tells you whether the river is running high or low for the date, not just what the staff gauge happens to read.
With more than 34 years of record behind it, that date-based comparison gives a better sense of what is ordinary for the season and what is a departure worth watching.
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.
