💧 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.

3 storm overflows are traced upstream of this gauge, the nearest 5.0 km away along the river. 0 report discharging now, 3 report not discharging.

Catchment Character

🌊 Urban & flashy Heavily built-up — rain runs off hard surfaces fast, so levels can spike within hours of 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

Rectangular flume, levels respond quickly to rainfall.

More detail

The catchment

A largely impervious catchment (mostly Weald Clay)but more permeable headwaters. Very mixed land use of rural tracts and urban centres; Crawley and Gatwick Airport are in the catchment.

The station

Rectangular flume, 7.1m wide at throat, and 1.48m wide rectangular side sluice. Removed from peak flows dataset in February 2018 (WINFAP Files v6).

How it measures flow

Flow bypasses the weir above 2.4m head (30 m3/s). Considerable flow in the road at levels approaching 3 m. Calibration based on current meter gaugings which extend beyond bankfull. Bypassing occurs at flows >30m3s-1; flows therefore uncertain in the highest range. One rating applied across period of record. Calibration based on current meter gaugings which extend beyond bankfull; rating overestimates flow beyond bankfull and is increasingly uncertain above 2.4m stage.

Flow regime

Responsive regime (reflecting growing urban contribution) and substantial effluent component (STWs at Crawley, Horley and Burstow) with a significant net import which has increasing over time (runoff therefore unrepresentative); otherwise moderate impact of artificial influences. Urban extent almost doubled between 1960 and 2002. Levels respond quickly to rainfall.

Patchy record in the 1970's.

Frequently asked questions

Is the River Mole at Kinnersley Manor flooding today?

The current level is 0.14m, which is within the typical range of 0.12 to 2.14m. Flooding is unlikely at this level.

Is the river level rising or falling at Kinnersley Manor?

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

Why is the level slowly falling?

When little or no rain has fallen for a while, a river level gradually drops as the water stored in the ground and soil drains away with nothing to replace it. This is called baseflow recession and is normal in dry spells. A gentle decline like this is expected and is not a sign of a problem — downstream gauges often recede a little faster than headwaters further upstream, and levels recover once rain returns.

What is a normal level for the River Mole at Kinnersley Manor?

The typical range at this station is 0.12m to 2.14m, based on Environment Agency historical data. Levels above 2.14m 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.
