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

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.
7 storm overflows are traced upstream of this gauge, the nearest 10.6 km away along the river. 0 report discharging now, 7 report 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 →
Warnings apply to a whole flood area, not necessarily this exact spot. Years before 2006 aren't covered by the EA's historic record.

🌊 Fairly flashyResponds fairly quickly to rain, with moderate baseflow between events.
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.

Located on the River Thame at Wheatley the ultrasonic gauging station superseded the upstream station at Shabbington (39038).
More detail
The catchment
The Thame drains a typical clay (principally Oxford Clay, some Greensand also) vale NW of the Chiltern escarpment. Land use is largely agricultural (considerable grassland) while the urban areas within the catchment include the town is Aylesbury.
The station
Multi-path US (cross- configuration).
How it measures flow
Full range, railway embankment ensures no bypassing. Skewed flow, weed-growth and summer temperature gradients can limit accuracy particularly at low flows (e.g. early autumn 2009).
Flow regime
Some spring flow contribution but responsive regime. Net import of water; sewage effluent is a significant component of low flows.
The flow record
Approximately 80 cumecs gauged in 01/2003. Flows in August 2017 affected by weed growth. Missing data in December 2019 due to station upgrade works.
Timing, not cause. Gauges can move together simply because the same rain fell on both.
Frequently asked questions
Is the River Thame at Wheatley flooding today?
The current level is 3.89m, which is within the typical range of 3.60 to 5.75m. Flooding is unlikely at this level.
Is the river level rising or falling at Wheatley?
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 Thame at Wheatley?
The typical range at this station is 3.60m to 5.75m, based on Environment Agency historical data. Levels above 5.75m 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.
