Under evaluation — not yet promoted, so treat as a second opinion.
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.
102 storm overflows are traced upstream of this gauge, the nearest 2.2 km away along the river. 1 reports discharging now, 95 report not discharging, and for 6 the monitor is offline or has not reported, so their status is not known.

36 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 24 areas linked to this gauge, nearest first.
This gauge has no rain model of its own, but it usually follows Littleborough: when about 6mm of rain falls near Littleborough in 6h, this gauge usually starts rising about 53 minutes later.
Timing, not cause. Gauges can move together simply because the same rain fell on both.
