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 8 flood
areas linked to this gauge (nearest 1.5 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 Butts Bridge 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).

More detail
The catchment
Headwaters drain Radnor Forest (developed on Silurian formations). Subdued relief in the lower valley (mostly Old Red Sandstone). Impervious catchment but extensive valley gravels provide some baseflow. Land use: mainly grassland in upper catchment, rough grazing with some forestry. Mixed farming with higher proportion of arable in the lower catchment.
The station
Velocity area station with rough stone control (at low flows) providing flood warning station. Station rebuilt in 1984. Width at bankfull is 21m. Stanchion span is 24m.
How it measures flow
Multiple ratings applied across period of record. Recent rating gauged to bankfull.
Flow regime
Runoff reduced by public water supply abstraction.
The flow record
July - Sept 1996 flows under review. Early peak flow data rejected due to uncertainty in pre-digital rating. Full period of record peak flow data reviewed and released in September 2019 (WINFAP Files v8). Ratings reviewed in 2022 and data reprocessed from 1988.

Frequently asked questions
Is the River Lugg at Butts Bridge flooding today?
The current level is 0.72m, which is below the typical range. Flooding is very unlikely at this level.
Is the river level rising or falling at Butts Bridge?
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 Butts Bridge?
The typical range at this station is 0.76m to 2.60m, based on Environment Agency historical data. Levels above 2.60m 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.
