Quick pick:
You'll be notified when this gauge is rising more than 0.10 mASD/hr — a sign of rapidly increasing water levels.
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 2011 for the 5 flood
areas linked to this gauge (nearest 5.8 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 Byton 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
🌊 Mixed responseA balance of quick runoff and slower groundwater baseflow.
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).

Flow-Duration Curve

Flat V Crump profile weir. Runoff reduced by groundwater abstraction for PWS.
More detail
The catchment
Headwaters drain Radnor Forest - underlain by Silurian bedrock. Impermeable formations are covered by extensive alluvial gravel deposits in the valleys. Predominantly grassland catchment supporting rough grazing, with some forestry.
The station
Flat V weir Crump profile weir, 1:20 cross-slopes, 12.5m wide constructed in 1971. Pre-1971, station was natural river section with stable riffle control. Above 2m left bank overtopped, right bank is steep cliff.
How it measures flow
Some shoaling u/s. Multiple ratings applied through the period of record.
Flow regime
Aquifer provides significant baseflow and moderates flood peaks. Runoff reduced by groundwater abstraction for PWS.
The flow record
Ratings reviewed in 2022 and data reprocessed from 1981. Full period of record peak flow data reviewed and released in September 2023 (WINFAP Files v12).

Frequently asked questions
Is the River Lugg at Byton flooding today?
The current level is 0.25m, which is below the typical range. Flooding is very unlikely at this level.
Is the river level rising or falling at Byton?
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 Lugg at Byton?
The typical range at this station is 0.28m to 1.30m, based on Environment Agency historical data. Levels above 1.30m 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.
