Quick pick:
You'll be notified when this gauge is rising more than 0.10 mASD/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.

Flood predictions aren't generated for
lock / structure gauges —
their levels are driven by gate operation,
not by catchment rainfall, so the forecast models would have no skill here.
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.
Downstream level
7 days
The level on the DOWNSTREAM side of this lock/weir structure — a separate EA
measure from the main (upstream) reading shown on the Current tab. Threshold bands
are computed from this gauge's own downstream history.

Flood history near this gauge
Official Environment Agency warnings issued since 2010 for the 15 flood
areas linked to this gauge (nearest 0.5 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 Marston Meysey 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
🌊 Mixed responseA balance of quick runoff and slower groundwater baseflow.
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.

Frequently asked questions
Is the Marston Meysey Brook at Whetstone Bridge flooding today?
The current level is 0.09m, which is within the typical range of -0.60 to 1.27m. Flooding is unlikely at this level.
Is the river level rising or falling at Whetstone Bridge?
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 Marston Meysey Brook at Whetstone Bridge?
The typical range at this station is -0.60m to 1.27m, based on Environment Agency historical data. Levels above 1.27m 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.
