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.
10 storm overflows are traced upstream of this gauge, the nearest 2.9 km away along the river. 0 report discharging now, 10 report not discharging.

7 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
Mixed geology: Upper catchment - Carboniferous Limestone. Lower catchment - Sandstone. Land use predominantly agriculture. Pasture land on both sides of river. The upper catchment is sustained by limestone groundwater; therefore although the Somerset levels respond quickly to rainfall, there is a long recession as the limestone drains. No major catchment changes.
The station
Station opened in 1964. Crump profile weir for low flows, crest 5.18m wide. Velocity area station for flows greater than 1.84 cumecs.
How it measures flow
Full range station. All flows in bank at station but may go out of bank upstream before bankfull at site. Daily flow rating reviewed in 01/2011. Rating unconfirmed by gaugings at highest flows. Lower section is rating for theoretical weir. Reliable extension of rating to bankfull but no data to allow extension beyond this. One peak flow rating across period of record. Bed mounted ADCP for non-modular.
Flow regime
Avalon Lake downstream of weir now gone. Effluent returns cause some flow augmentation. Minor groundwater abstractions in catchment. More discharge than abstraction.
The flow record
Downstream summer weed growth can affect modular limit. Water year 1965/1966 rejected due to the likely underestimation of true AMAX. Full period of record peak flow data reviewed and released in August 2021 (WINFAP Files v10).
Timing, not cause. Gauges can move together simply because the same rain fell on both.
Frequently asked questions
Is the River Sheppey at Fenny Castle 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 Fenny Castle?
Based on the most recent readings, the level is currently falling slightly. The chart above shows the last 12 hours of measurements by default (up to 7 days), updated roughly every 15 minutes.
Why is the level slowly falling?
When little or no rain has fallen for a while, a river level gradually drops as the water stored in the ground and soil drains away with nothing to replace it. This is called baseflow recession and is normal in dry spells. A gentle decline like this is expected and is not a sign of a problem — downstream gauges often recede a little faster than headwaters further upstream, and levels recover once rain returns.
What is a normal level for the River Sheppey at Fenny Castle?
The typical range at this station is 0.09m to 0.47m, based on Environment Agency historical data. Levels above 0.47m 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.
