You'll be notified when this gauge is rising more than 0.10 mASD/hr — a sign of rapidly increasing water levels.
Beta. You'll be notified when a flood wave detected at an upstream gauge is forecast to reach this station, with an estimated arrival time. Accuracy improves as we verify more waves.
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 2015 for the 7 flood
areas linked to this gauge (nearest 3.8 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 Wye 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
🌊 Groundwater-fedSlow 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).

Flow-Duration Curve
Daily flow (m³/s) exceeded each % of the time — a steep curve is flashy, a flat one is steady. Q5 high · Q50 median · Q95 low.
Triangular crump weir (width 7.61m) - drowns at <3 cumecs (no flow adjustment) and velocity-area station throughout the peak flow range. Weed growth can cause overestimation of flows.
More detail
The catchment
The east and west branches of the River Stour flow over impermeable (mainly) Weald Clay; below Ashford (the only major settlement). Catchment is half-and-half impervious and pervious. A rural catchment with mixed land use.
The station
Triangular crump weir (width 7.61m) - drowns at <3 cumecs (no flow adjustment). Velocity area station (just downstream) for high flows. The River Stour is wide & shallow at the gauging station, the floodplain is limited by the railway line. Previously a broad crested weir (1960-62) which was subject to premature drowning frequently due to weed growth and the low design of the weir sill.
How it measures flow
The weir conforms to British Standards up to 0.3m stage. Wye Bridge contains 5 arches with secondary arches between the river & railway line to accommodate very high flows. Bank is overtopped at 1.65m stage, flow contained in floodplain to 1.85m stage. Inspection of the gauge in 2002 for a rating review suggests a secondary flow path upstream of Wye Bridge possibly results in flow through the secondary culverts, bypassing the gauge. Weed growth can cause overestimation of flows. Siltation also an issue. In 1962, sill was raised and the downstream section was dredged approx. 23cm. It was proposed to clear the weed annually to prevent further drowning, however conservation concerns have halted this in recent years. Peak flow rating beyond 0.8m derived from hydraulic modelling, confirmed with gaugings to 1.6m.
Flow regime
M20 motorway & Channel Tunnel rail link are increasing the development pressures on the catchment. Effluent from Ashford is a significant component of low flows; small net import of water. Flood retention reservoirs above Ashford (constructed 1990-2). Hydrographs show evidence of upstream mill sluice operation (declining); regulation in early records from Wye Mill 160m upstream. The catchment exhibits little storage.
The flow record
Low confidence in this site. Data reprocessed in 2010; summer 2007 high flows significantly modified, 2000 flows added. 1976 drought minimum (lowest flow on record) estimated. Full period of record peak flow data reviewed and released in September 2023 (WINFAP Files v12).

Frequently asked questions
Is the Great Stour at Wye flooding today?
The current level is 0.08m, which is below the typical range. Flooding is very unlikely at this level.
Is the river level rising or falling at Wye?
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 Great Stour at Wye?
The typical range at this station is 0.11m to 1.00m, based on Environment Agency historical data. Levels above 1.00m 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.
