💧 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.

4 storm overflows are traced upstream of this gauge, the nearest 11.2 km away along the river. None of their monitors has a current status (offline, or no report in the last 2 hours), so whether any is discharging is not known.

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.

About this gauge

Crump profile Flat V weir from 1992 that replaced velocity-area station with natural rock step control approximately 150m downstream of cableway.

More detail

The catchment

High relief headwaters and broad bottomed valleys of moderate slope with Boulder Clay and fluvial gravel. Solid geology predominantly Ordovician slates and shales. Land use: moorland, forestry and pasture.

The station

From Feb 1992 Crump profile Flat V (1:20) weir, 12.4m wide, 0.72m high wing walls, replaced velocity area station with natural rock step control approx. 150m d/s of cableway. Gravel bed. Right bank floodplain approx. 50m wide, partially crossed by cableway.

How it measures flow

Cableway rated. Right bank floodplain approximately 50m wide, partially crossed by cableway. Two ratings applied across period of record, the most recent is valid from April 1992 when weir installed. Ratings fit well to corresponding gaugings post-1992. Theoretical rating on open channel pre-1992 means flows are highly uncertain, although fit to available gaugings in the peak flow range is within acceptable tolerances.

Flow regime

Sewage effluent has insignificant effect upon flow regime.

The flow record

Water year 1991/1992 rejected due to the true AMAX occurring during a missing period. Full period of record peak flow data reviewed and released in August 2021 (WINFAP Files v10).
