Quick pick:
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 2013 for the 11 flood
areas linked to this gauge (nearest 0.7 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 Weybridge 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).

More detail
The catchment
Diverse geology and land use. Largely permeable upper catchment (Chalk and Upper Greensand of the North Downs); impermeable Tertiary formations dominate the lower catchment. Land use: rural tracts with mixed woodland; considerable suburban development below the headwaters.
The station
A multi-path cross-configuration ultrasonic replaced a single-path US (Harwell design) in 2003.
How it measures flow
Gaugings were used to develop adjustment factors. Weed-growth, low velocities and velocity distribution caused problems.
Flow regime
U/s storage produces some flood attenuation. Responsive regime. The confluence with canal is just u/s.
The flow record
No data between January 2019 and July 2020 due to gauge failure.

Frequently asked questions
Is the River Wey at Weybridge flooding today?
The current level is 0.99m, which is within the typical range of 0.96 to 1.40m. Flooding is unlikely at this level.
Is the river level rising or falling at Weybridge?
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 Wey at Weybridge?
The typical range at this station is 0.96m to 1.40m, based on Environment Agency historical data. Levels above 1.40m 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.
