💧 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 13.8 km away along the river. 0 report discharging now, 2 report not discharging.

7 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 →

Catchment Character

🌊 Mixed response A balance of quick runoff and slower groundwater baseflow.

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.

The physical character of the land that drains to this gauge, and how it shapes its flood response — from the National River Flow Archive (UKCEH).

About this gauge

Flat-V weir on the River Rye in a rural catchment.

More detail

The catchment

Geology: Jurassic Limestone, clays and sandstones. Predominantly rural catchment with moorland headwaters and arable in lower valleys.

The station

Flat-V weir, 12m wide. Station added to peak flows dataset in August 2021 (WINFAP Files v10).

How it measures flow

Flat V weir subject to drowning below QMED, some out of bank flow but no by-passing. Theoretical rating amended by hydraulic modelling to cover non-modular flow range. One peak flow rating across period of record.

Flow regime

Significant groundwater abstractions.

The flow record

June 2005 peak estimated at 75 cumecs using hydraulic model.
