💧 Storm overflows upstream of this gauge

None of the storm overflows FloodRadar holds is traced upstream of this gauge on the mapped river network. That is not the same as none: the map leaves out many small streams and culverts, so an overflow it cannot place may still drain here, and not every company publishes every overflow. Those nearby are listed below.

Nearby, connection not known

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 →

Catchment Character

🌊 Mixed response A 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).

About this gauge

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).

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 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.
