About River Derwent at Barmby

River Derwent at Barmby is a gauged river in England.

The river

This station sits on the River Derwent in England, and the record here runs for 28 years. That length of record is enough to show how the channel behaves through wet and dry spells without turning one high or low into a rule.

The seasonal pattern is modest but clear. The highest month is January, with a typical level of 2.19 m (7.19 ft), while the lowest month is May, with a typical level of 1.95 m (6.38 ft). The typical annual swing is 24.5 cm (9.6 in), so the difference from one season to the next is not huge, but it is enough to matter for moorings, bank access, and shallow edges.

The extremes show the reach the river can take. The record high is 4.04 m (13.24 ft) in November 2000, and the record low is 0.93 m (3.04 ft) in June 2010. For anyone living beside the water or watching for fishable depth, those two marks are the outer bounds of what this station has seen.

What the numbers say

The seasonal note fits a temperate river: levels tend to rise in the cooler months and ease back in late spring. Here, the highest typical month is January, not a spring month, so the station’s own record is more useful than any general rule. The river has also shown a low point in June 2010 that sits well below the typical May level, which is the kind of gap that can change launching, intake depth, and shore access.

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. That is better than raw elevation because a level only becomes useful when you know what is normal for this date at this gauge. A reading near the median means the river is sitting close to its usual place for the season; a reading well above or below it tells you that this station is running outside its normal pattern.

At this station, the figures are from the Environment Agency, and the 28-year record gives that comparison more weight than a single day on its own.

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.

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.
