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

How often this river runs high

In a typical year this gauge reaches its typical high of 0.40 m on about 37 days. This year so far: 12 days.

Counted from each day's highest reading. Days with missing or implausible readings are left out, so a year marked patchy may have run high more often than shown. The darker part is days above 0.90 m, the level this gauge tops only a few days a year.

Catchment Character

🌊 Groundwater-fed Slow and steady — fed largely by groundwater, so levels change gradually, not in sudden spikes.

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

Trapezoidal weir gauging a predominantly Chalk catchment with primarily arable land and with significant artificial influences.

More detail

The catchment

Predominantly Chalk catchment partly overlain with Boulder Clay in NW. Primarily arable land.

The station

Trapezoidal cross-section weir with triangular profile crest, 6.1m broad. Also called Haslingfield (Burnt Mill). Consistent records available of groundwater pump operation. Pre barrage fish pass and eel tiles installed.

How it measures flow

Weir drowns at high flows, starting from 0.48m stage and drowns completely at higher flows, worsened during summer due to weed growth downstream. Non-modular conditions are accounted for in the current rating. Rating modified by current meter measurements to correct for drowning and applied across period of record. Gauging station is used as part of the Rhee groundwater support scheme, which triggers at a combined flow of 301 l/s to maintain flow. One peak flow rating across period of record.

Flow regime

Substantial groundwater abstractions for public water supply, plus industrial and agricultural abstractions. Some effluent returns. Augmentation from ground water sources to regulate river flow - scheme aims to maintain minimum 0.3 cumecs flow at gauging station.

The flow record

Daily mean flow from 24/10/2013 to 04/03/2015 was updated after September 2014 to compensate for site maintenance. Full period of record peak flow data reviewed and released in October 2018 (WINFAP Files v7) and August 2025 (WINFAP Files v14).

Frequently asked questions

Is the River Rhee at Haslingfield Burnt Mill flooding today?

The current level is 0.08m, which is within the typical range of 0.07 to 0.40m. Flooding is unlikely at this level.

Is the river level rising or falling at Haslingfield Burnt Mill?

Based on the most recent readings, the level is currently steady. The chart above shows the last 12 hours of measurements by default (up to 7 days), updated roughly every 15 minutes.

What is a normal level for the River Rhee at Haslingfield Burnt Mill?

The typical range at this station is 0.07m to 0.40m, based on Environment Agency historical data. Levels above 0.40m are higher than usually seen and may indicate a flood risk.

How often is this river level data updated?

Readings are supplied by the Environment Agency gauge. FloodRadar checks for updates roughly every 15 minutes; the timestamp above shows how recent the latest available reading is.
