💧 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.

1 storm overflow is traced upstream of this gauge, the nearest 11.8 km away along the river. 0 report discharging now, 1 reports not discharging.

1 other overflow within 6 km is downstream of this gauge or on another branch of the river network, so it is 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 →

Catchment Character

🌊 Fairly flashy Responds fairly quickly to rain, with moderate baseflow between events.

Your catchment is all the land that drains rainfall into the river above this gauge. Its character — how steep, wet, wooded, urban or chalky that land is — decides how fast rain here turns into a rising river. A steep, bare or clay catchment is “flashy” (rises and falls quickly, floods easily); a flat, chalk or well-wooded one is slow and steady. The tiles below put numbers to that; the flow-duration curve reads left-to-right from the river’s typical high flows (Q5) down to its low flows (Q95) — a steep curve means a flashy river.

About this gauge

A gauging station located in the lower River Quin catchment that is located within the River Lee system.

More detail

The catchment

A mainly impervious catchment with extensive glacial deposits overlying Chalk. Agricultural land use predominates but there is some urban development close to the gauging station.

The station

Flat V weir, 4.5m wide. Shallow depth of approach.

How it measures flow

Calibration assumes station is not subject to drowning.

Flow regime

Net export of water has increasing from the mid-1980s. Gw abstractions can be especially significant during droughts e.g. late-1990. Stable baseflow but responsive to storm events; sewage effluent discharge pattern also sometimes detectable.
