Quick pick:
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.
Get notified when recent rainfall near this gauge crosses its learnt rise trigger — an early "watch"
signal, typically hours before a rise. Experimental; not an official flood warning.

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.

Warnings apply to a whole flood area, not necessarily this exact spot. Years before 2006 aren't covered by the EA's historic record.

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
Axe rises as underground river from cave at Wookey Hole. Geology includes measures of Old Red Sandstone, Carboniferous Limestone and Triassic conglomerates. Complex structure with numerous springs and swallows due to fissured limestones with impermeable beds. Catchment area probably underestimated: northern and western limits of topographic catchment approximate to the underground catchment but the eastern limit of the latter likely to lie considerably farther east than the former. Land use is rural.
The station
Also known as Henley, owned by Bristol water.
How it measures flow
Flume gauge installed to measure medium and low flows. Data from 50s/60s considered bad. Leaking sluice gate, 0.8-0.9m goes over the top of gate.
Flow regime
Abstraction and discharge u/s for mirror pool and paper mill.

Frequently asked questions
Is the River Axe at Wookey flooding today?
The current level is 0.40m, which is below the typical range. Flooding is very unlikely at this level.
Is the river level rising or falling at Wookey?
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 Axe at Wookey?
The typical range at this station is 0.42m to 0.77m, based on Environment Agency historical data. Levels above 0.77m 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.
