💧 Storm overflows upstream of this gauge

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.

1 storm overflow is traced upstream of this gauge, the nearest 7.0 km away along the river. 0 report discharging now, 1 reports not discharging.

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

🌊 Groundwater-fed Slow and steady — fed largely by groundwater, so levels change gradually, not in sudden spikes.

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

The ultrasonic gauging station is located in the middle reaches of the River Windrush.

More detail

The catchment

A pervious (Oolitic L'st) catchment (with some low-permeability tracts) on the dip-slope of the Cotswolds. Predominantly rural - Witney is the largest settlement.

The station

Multi-path ultrasonic commissioned in December, 1995. Previously two adjustable radial gate (sharp-crested) weirs.

How it measures flow

It is principally a low flow station. Flood flows are commonly not calculated.

Flow regime

Large baseflow component but responsive to storm events. Negligible disturbance to the natural flow regime.

The flow record

Some early flow data (from 1942) held by the measuring authority for the original rhymer weir. There is also a very patchy record pre-1977. Drowning is very rare but high flows are unreliable.

Is the River Windrush at Worsham flooding today?

The current level is 0.27m, which is below the typical range. Flooding is very unlikely at this level.

Is the river level rising or falling at Worsham?

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 Windrush at Worsham?

The typical range at this station is 0.30m to 1.62m, based on Environment Agency historical data. Levels above 1.62m 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.
