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.

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.
151 storm overflows are traced upstream of this gauge, the nearest 3.6 km away along the river. 0 report discharging now, 142 report not discharging, and for 9 the monitor is offline or has not reported, so their status is not known.

22 other overflows within 6 km are downstream of this gauge or on another branch of the river network, so they are not listed.
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.

Flood areas linked to this gauge
Flood warnings and alerts are issued for whole areas. These are the 37 areas linked to this gauge, nearest first.
This gauge has no rain model of its own, but it usually follows Broomstairs Bridge: when about 6mm of rain falls near Broomstairs Bridge in 6h, this gauge usually starts rising about 2 hours later.
Timing, not cause. Gauges can move together simply because the same rain fell on both.
Frequently asked questions
Is the River Mersey at Northenden flooding today?
The current level is 0.28m, which is within the typical range of 0.27 to 1.80m. Flooding is unlikely at this level.
Is the river level rising or falling at Northenden?
Based on the most recent readings, the level is currently falling slightly. The chart above shows the last 12 hours of measurements by default (up to 7 days), updated roughly every 15 minutes.
Why is the level slowly falling?
When little or no rain has fallen for a while, a river level gradually drops as the water stored in the ground and soil drains away with nothing to replace it. This is called baseflow recession and is normal in dry spells. A gentle decline like this is expected and is not a sign of a problem — downstream gauges often recede a little faster than headwaters further upstream, and levels recover once rain returns.
What is a normal level for the River Mersey at Northenden?
The typical range at this station is 0.27m to 1.80m, based on Environment Agency historical data. Levels above 1.80m 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.
