💧 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.

121 storm overflows are traced upstream of this gauge, the nearest 1.2 km away along the river. 0 report discharging now, 109 report not discharging, and for 12 the monitor is offline or has not reported, so their status is not known.
