💧 Storm overflows upstream of this gauge

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.

2 storm overflows are traced upstream of this gauge, the nearest 8.5 km away along the river. 0 report discharging now, 2 report not discharging.

Nearby, connection not known

Within 6 km in a straight line, but the river map cannot say whether their water passes this gauge.

2 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 →
