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
90 days
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.
6 storm overflows are traced upstream of this gauge, the nearest 7.2 km away along the river. 0 report discharging now, 5 report not discharging, and for 1 the monitor is offline or has not reported, so their status is not known.

3 other overflows within 6 km are downstream of this gauge or on another branch of the river network, so they are 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 →
Warnings apply to a whole flood area, not necessarily this exact spot. Years before 2006 aren't covered by the EA's historic record.

🌊 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).

More detail
The catchment
Predominantly Chalk; Upper Greensand and Gault in upper catchment. Rural land use. No major catchment changes.
The station
Crump profile weir, crest 10.7m broad. Full range station; opened in 1966. Subject to drowning and bypassing at high discharges.
How it measures flow
Sluice control upstream for river regulation. Minor bypassing. Heavy weed growth during summer months. Good data set with check gaugings confirming original rating. One peak flow rating applied across period of record. Rating extended based on flood gaugings. Upper limit of rating is 1.30m/42.3 cumecs.
Flow regime
Natural to within 10% at Q95. Direct abstraction from the river for spray irrigation. Sluice control upstream for river regulation and groundwater abstractions.
The flow record
There is lower confidence in flow data before 1992, hence this data is marked as an unrepresentative period. Full period of record peak flow data reviewed and released in September 2019 (WINFAP Files v8) and in September 2023 (WINFAP Files v12).

Frequently asked questions
Is the River Wylye at South Newton flooding today?
The current level is 0.13m, which is below the typical range. Flooding is very unlikely at this level.
Is the river level rising or falling at South Newton?
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 Wylye at South Newton?
The typical range at this station is 0.14m to 0.65m, based on Environment Agency historical data. Levels above 0.65m 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.
