You'll be notified when this gauge is rising more than 0.10 m/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.

River Flow

Daily mean discharge (m³/s) with the daily min–max band, from the EA Hydrology API. Flow is the volume of water passing the gauge — often a more direct flood signal than level.

Storm overflows whose water reaches this gauge on the mapped river network, nearest first by distance along the river. The status is each water company's monitor: it says whether an overflow is discharging, not how much or what it contains.
3 storm overflows are traced upstream of this gauge, the nearest 6.9 km away along the river. 0 report discharging now, 3 report not discharging.

1 other overflow within 6 km is downstream of this gauge or on another branch of the river network, so it is not listed.
These are the water companies' monitor statuses; a spill does not by itself explain a change in the gauge level. River connections and distances are traced on OS Open Rivers (edition 2026-04), which leaves out many small channels. Explore the sewage map →

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.

🌊 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.

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.
Timing, not cause. Gauges can move together simply because the same rain fell on both.
Frequently asked questions
Is the River Lugg at Butts Bridge flooding today?
The current level is 0.74m, 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 12 hours of measurements by default (up to 7 days), 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 supplied by the Environment Agency gauge. FloodRadar checks for updates roughly every 15 minutes; the timestamp above shows how recent the latest available reading is.
