💧 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.

13 storm overflows are traced upstream of this gauge, the nearest 1.4 km away along the river. 0 report discharging now, 13 report not discharging.

17 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

🌊 Steep & flashy Steep catchment sheds rain quickly — expect fast, sharp rises after heavy rain.

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

Velocity area station approx. 36m wide at bankfull.

More detail

The catchment

Upland catchment with peat covered moorlands in the headwaters. Geology: predominantly Millstone Grit, with some western tributaries draining Carboniferous Limestone. Predominantly pasture.

The station

Velocity area station approx. 36m wide at bankfull. Important flood forecasting station.

How it measures flow

Downstream shoal acts as a control, but shoal and rating are not too stable. All but extreme flows contained. Four peak flow ratings applied over period of record. Spot gauged close to highest flow in record.

Flow regime

Quite responsive. Flows substantially affected by Derwent reservoirs.

The flow record

Analomous flows in Aug/Sept 1975. The pre-1976 data is thought to be less reliable due to inconsistencies over the way the datum change has been handled.
