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 2008 for the 5 flood
areas linked to this gauge (nearest 7.0 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 Wheatley 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
🌊 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.
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).

Located on the River Thame at Wheatley the ultrasonic gauging station superseded the upstream station at Shabbington (39038).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.

Frequently asked questions
Is the River Thame at Wheatley flooding today?
The current level is 3.86m, 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 7 days of measurements, 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 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.
