About Earn at Forteviot Bridge
Earn at Forteviot Bridge is a gauged river in Scotland.
The watershed
The station drains 782 km2 (302 sq mi) above the bridge, so this reading reflects a fairly broad upstream reach rather than a single bank or tributary.
For people living near the water, that matters most when rain comes in a run of wet days. In this part of Scotland, winter and spring are often the times to watch, and the river can also respond quickly to heavy rain later in the year. The pattern here is not flat through the year: the typical high month is January and the typical low month is July.
That seasonal swing is part of the day-to-day planning for anyone with a low access, a pump, or a mooring near the channel. A river that sits near its winter pattern in January is behaving close to its usual seasonal high; by July it is often much lower, which can tighten margins for shallow crossings and intakes.
What the numbers say
The station has more than 36 years on record, which gives the recent reading context beyond a single wet spell or dry week.
The highest level in the record was 3.09 m (10.13 ft) in December 2015. The lowest was -0.1 m (-0.32 ft) in July 2018. That span shows how far this reach has moved under different weather patterns.
The typical annual swing is 60.9 cm (24 in). For a cottager, angler, or farmer near the water, that is the kind of seasonal change that can shift where the edge of the flow sits, where a boat can be handled, and how much clearance is left under a crossing.
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’s record, not against a raw zero or an absolute elevation. That is the better guide because it shows whether the river is running above or below its usual level for this date.
This station is operated by SEPA. With more than 36 years of records, the date-specific median gives a practical reference for what is normal at this time of year on this reach, which is more useful than a standalone height number when you are deciding how to use the river today.
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.
