You'll be notified when this gauge is rising more than 0.10 mASD/hr — a sign of rapidly increasing water levels.
Beta. You'll be notified when a flood wave detected at an upstream gauge is forecast to reach this station, with an estimated arrival time. Accuracy improves as we verify more waves.
You'll be notified when a new storm-overflow (sewage) discharge starts within ~3 km of this gauge, based on the water companies' near-real-time feeds.

Flood history near this gauge
Official Environment Agency warnings issued since 2012 for the 6 flood
areas linked to this gauge (nearest 2.1 km away).
Warnings apply to a whole flood area, not necessarily this exact spot. Years before 2006 aren't covered by the EA's historic record.
See also the Elkesley flood history.
Geographic coordinates may reflect the access point for the gauge, and not the precise location in the watercourse that it is taking readings from.
Catchment Character
🌊 Groundwater-fedSlow 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).

More detail
The catchment
Catchment rises on Magnesian Limestone with subordinant Permian Marl; mainly underlain by Sherwood Sandstone. Predominantly rural; part of Bolsover and Shirebrook in headwaters.
The station
Station sites where Poulter leaves Sherwood Sandstone outcrop. Original 4.88m wide Crump profile weir submerged from late 1972 by mining subsidence; channel regraded in 1981, but no solution. Ultrasonic gauge installed in 1992 revived the station and was replaced by a LaserFlow gauge in October 2017.
How it measures flow
Laserflow capable of measuring full range of flows. Extreme high flows suspect due to backing up from River Idle and inaccessibility for gauging.
Flow regime
Minor augmentation from sewage; inline lakes in Clumber and Welbeck Parks ensure sluggish response.
The flow record
Periods of missing data from 2007 until 2009 due to difficulties with ultrasonic gauge. Early flow record for the ultrasonic gauge did not measure bypass flow. Further periods of suspect data and edited data from 2015-2019 due to measurement problems. The laser flow gauge post 2019 measures the full range of flows to a better standard.

Frequently asked questions
Is the River Poulter at Twyford Bridge flooding today?
The current level is 0.94m, which is within the typical range of 0.16 to 1.42m. Flooding is unlikely at this level.
Is the river level rising or falling at Twyford Bridge?
Based on the most recent readings, the level is currently steady. The chart above shows the last 7 days of measurements, 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 Poulter at Twyford Bridge?
The typical range at this station is 0.16m to 1.42m, based on Environment Agency historical data. Levels above 1.42m are higher than usually seen and may indicate a flood risk.
How often is this river level data updated?
Readings are taken by the Environment Agency gauge roughly every 15 minutes and FloodRadar refreshes its data continuously, so the level shown is normally less than an hour old.
