Natural Resources Wales does not publish a typical range for this gauge, so FloodRadar
works one out from its own history (its usual daily lows and highs). It is not an official flood threshold.

Experimental model fusing soil moisture, river flow, groundwater and catchment
character. The shaded band is its 10–90% range, widened so that about 80% of recent outcomes fall inside it.
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.
11 storm overflows are traced upstream of this gauge, the nearest 5.1 km away along the river. 0 report discharging now, 10 report not discharging, and for 1 the monitor is offline or has not reported, so their status is not known.

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. Sewage & storm overflows →
