About River Rother at Killamarsh
River Rother at Killamarsh is a gauged river in England.
Season by season
In this temperate reach, the usual high water comes in February at 0.22 m (0.71 ft), then the river eases down toward the summer low in July at 0.04 m (0.13 ft). That 17.4 cm (6.9 in) annual swing is not large, but it is enough to matter for a shallow landing, a bank-side peg, or anything sitting close to the waterline.
For most users, that pattern means late winter and early spring are the times to watch for higher levels, while summer is when the channel tends to run lower. On a quiet stretch like this, small changes can be the difference between enough depth for a boat, enough cover for fish, or an intake sitting comfortably above the surface.
Records and rises
The highest reading in the record is 3.5 m (11.48 ft) in April 2026. The lowest is -0.12 m (-0.41 ft) in August 2025. Those two marks show how far the station can move when conditions shift.
The record set spans 26 years, so these extremes sit within a reasonably long local history. This page does not give a fastest 24-hour rise, so there is no warning-time figure to quote here. If you use the river for access, fishing, or pumping, the useful lesson is simple: the range between the seasonal norm and the record extremes is much bigger than the day-to-day level you may see at the bank.
Reading the hero number
The hero number on this page compares today’s level with the median for the same calendar day across the station’s record. That is more useful than raw elevation because it tells you whether the river is running above or below its usual position for this date, rather than just how high it is in absolute terms.
At this station, the data come from the Environment Agency. With 26 years on record, that date-matched comparison gives a better sense of what is ordinary for the day, and what is worth a second look.
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.
