You'll be notified when this gauge is rising more than 0.10 m/hr — a sign of rapidly increasing water levels.
Beta. You'll be notified when a flood wave detected at an upstream gauge is forecast to reach this station, with an estimated arrival time. Accuracy improves as we verify more waves.
You'll be notified when a new storm-overflow (sewage) discharge starts within ~3 km of this gauge, based on the water companies' near-real-time feeds.

Flood history near this gauge
Official Environment Agency warnings issued since 2012 for the 7 flood
areas linked to this gauge (nearest 0.6 km away).
Warnings apply to a whole flood area, not necessarily this exact spot. Years before 2006 aren't covered by the EA's historic record.
See also the Seaton Mill, Barepot, Workington flood history.
Geographic coordinates may reflect the access point for the gauge, and not the precise location in the watercourse that it is taking readings from.
Catchment Character
🌊 Steep & flashySteep catchment sheds rain quickly — expect fast, sharp rises after heavy rain.
Your catchment is all the land that drains rainfall into the river above this gauge. Its character — how
steep, wet, wooded, urban or chalky that land is — decides how fast rain here turns into a rising river. A steep, bare or clay
catchment is “flashy” (rises and falls quickly, floods easily); a flat, chalk or well-wooded one is
slow and steady. The tiles below put numbers to that; the flow-duration curve reads left-to-right
from the river’s typical high flows (Q5) down to its low flows (Q95) — a steep curve means a flashy river.
The physical character of the land that drains to this gauge, and how it shapes its flood response — from the National River Flow Archive (UKCEH).

Most downstream station on the Derwent, opened to replace Camerton (75002).
More detail
The catchment
The river Derwent starts at Styhead Tarn beneath Scafell Pike and runs north through the Borrowdale valley into Derwentwater then Bassenthwaite lake and eventually joins the sea at Workington. Once it leaves Bassenthwaite it is joined by some significant tributaries (Cocker and Marron). The catchment is predominantly rural but many of the rivers and streams have been artificially straightened and modified in the past.
The station
The station was built to replace Camerton which was destroyed in the flood Nov 2009. Station added to peak flows dataset in September 2019 (WINFAP Files v8).
How it measures flow
Levels at the station are subject to surging during windy conditions which can impact levels by 20-30mm. Major floods such as November 2009 and December 2015 have significant bypassing flows on the right bank, which have been assessed by hydraulic modelling and comparison with upstream stations. A cableway is installed and all gaugings are done at the station. Control is Yearl Weir 300m downstream which incorporates two fish passes and a broad crested weir section. An offtake sluice is located close to the weir left bank which can be opened to aid fish passage with an effect on the rating at low flows. One peak flow rating valid across period of record.
The flow record
Low flows are difficult to measure as velocities are very low.

Frequently asked questions
Is the River Derwent at Seaton Mill, Barepot, Workington flooding today?
The current level is 0.50m, which is below the typical range. Flooding is very unlikely at this level.
Is the river level rising or falling at Seaton Mill, Barepot, Workington?
Based on the most recent readings, the level is currently steady. The chart above shows the last 7 days of measurements, updated roughly every 15 minutes.
What is a normal level for the River Derwent at Seaton Mill, Barepot, Workington?
The typical range at this station is 0.51m to 1.50m, based on Environment Agency historical data. Levels above 1.50m are higher than usually seen and may indicate a flood risk.
How often is this river level data updated?
Readings are taken by the Environment Agency gauge roughly every 15 minutes and FloodRadar refreshes its data continuously, so the level shown is normally less than an hour old.
