Geographic coordinates may reflect the access point for the gauge, and not the precise location in the watercourse that it is taking readings from.
Gauges connected to this river, and others nearby. A distance “by river” follows the river on the map; any other is in a straight line.
Distances by river: OS Open Rivers. Contains OS data © Crown copyright and database rights 2026.
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.
38 storm overflows are traced upstream of this gauge, the nearest 9.0 km away along the river. 2 report discharging now, 35 report not discharging, and for 1 the monitor is offline or has not reported, so their status is not known.
30 more further upstream, up to 76.4 km away along the river.
Also discharging now further upstream: Corwen WwTW Storm Overflow (42.5 km), Church Street Llanuwchllyn Storm Overflow (76.4 km).
Within 6 km in a straight line, but the river map cannot say whether their water passes this gauge.
3 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 →

In a typical year this gauge reaches its typical high of 1.37 m on about 22 days. This year so far: 5 days.
Counted from each day's highest reading. Days with missing or implausible readings are left out. The darker part is days above 1.76 m, the level this gauge tops only a few days a year.
The current level is 1.10m, which is within the typical range of 0.42 to 1.37m. Flooding is unlikely at this level.
Based on the most recent readings, the level is currently rising slightly. The chart above shows the last 12 hours of measurements by default (up to 7 days), updated roughly every 15 minutes.
The typical range at this station is 0.42m to 1.37m, based on Natural Resources Wales historical data. Levels above 1.37m are higher than usually seen and may indicate a flood risk.
Readings are supplied by the Natural Resources Wales gauge. FloodRadar checks for updates roughly every 15 minutes; the timestamp above shows how recent the latest available reading is.
