💧 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.

31 storm overflows are traced upstream of this gauge, the nearest 11.3 km away along the river. 1 reports discharging now, 30 report not discharging.

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.

About this gauge

Full range multi-path ultrasonic gauge. Flood flows from upper part of catchment diverted to the Sea Cut (measured at 27033).

More detail

The catchment

Permeable catchment draining the southern slopes of the North Yorkshire moors, geology consists of Sandstones, grits and limestone of the Middle Oolites overlain by clay in the lower catchment. Contributing catchment area varies due to Sea Cut diversion. Extensive floodplain upstream of gauge. No known catchment changes.

The station

Full range multipath ultrasonic gauge, installed in 2001 under the A64 road bridge. Flood flows from the upper catchment diverted to the Sea Cut (measured at 27033).

How it measures flow

Ultrasonic gauge in relatively straight approach channel. Transducers mounted on sloping racks up to bankfull with higher paths in vertical racks on bridge piers. Some flow behind piers in flood conditions is allowed for in the gauge calculations. Bankfull stage given is channel bank, but all flows contained by higher embankments set back on floodplain.

Flow regime

Relatively slow response catchment with significant baseflow component. Artificial influences on flow include straightened sections and drainage for agriculture upstream of the Rye confluence. Flood flows from 88.8 sq.km of the Derwent headwaters are diverted (~6% of the catchment) via the Sea Cut (27033) - relatively small impact downstream of Rye confluence.

The flow record

Issues with the ultrasonic gauge 19/02/10 to 26/04/10, data during this period inaccurate and marked as suspect. Full period of record peak flow data reviewed and released in September 2019 (WINFAP Files v8).
