The official "typical high" for this gauge is routinely exceeded (often the case on
regulated rivers), so FloodRadar uses a threshold computed from this station's own data.

Quick pick:
You'll be notified when this gauge is rising more than 0.10 m/hr — a sign of rapidly increasing water levels.
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.
Get notified when recent rainfall near this gauge crosses its learnt rise trigger — an early "watch"
signal, typically hours before a rise. Experimental; not an official flood warning.

River Flow
90 days
Daily mean discharge (m³/s) with the daily min–max band, from the EA Hydrology API. Flow is the volume of water passing the gauge — often a more direct flood signal than level.

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.
18 storm overflows are traced upstream of this gauge, the nearest 8.2 km away along the river. 0 report discharging now, 17 report not discharging, and for 1 the monitor is offline or has not reported, so their status is not known.

3 other overflows within 6 km are downstream of this gauge or on another branch of the river network, so they are not listed.
These are the water companies' monitor statuses; a spill does not by itself explain a change in the gauge level. River connections and distances are traced on OS Open Rivers (edition 2026-04), which leaves out many small channels. Explore the sewage map →

The darker part is days above 1.10 m, the level this gauge tops only a few days a year.
Flood history near this gauge
Official Environment Agency warnings issued since 2012 for the 8 flood
areas linked to this gauge (nearest 1.6 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.

🌊 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
Moderate to low relief catchment underlain by the Notts coalfield. The Maun rises on generally sandy facies of the Magnesian Lst, crosses onto Sherwood Sst, the gauge sited close to the junction with the Mercia Mudst. Upper catchment dominated by urban centres (Mansfield) and mining spoil; middle and lower reaches rural and forest.
The station
Replacing d/s station (28045). Data from cross-correlation gauge commences in 2019. Prior measurement from Flat V weir with 1:10 cross slopes, Crump profile, 5.2m wide, wing walls at 0.64m.
Flow regime
Subdued response with WRW effluent augmenting low flows.
The flow record
No daily flow data available July 2013 - September 2016 due to subsidence of the weir. Flows from October 2016 onwards are calculated through a new rating and from February 2019 onwards from the cross-correlation gauge. June 2007 high flows were over the wingwalls of the structure.

Frequently asked questions
Is the River Meden at Perlethorpe flooding today?
The current level is 0.51m, which is within the typical range of 0.18 to 0.98m. Flooding is unlikely at this level.
Is the river level rising or falling at Perlethorpe?
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 Meden at Perlethorpe?
The typical range at this station is 0.18m to 0.98m, based on Environment Agency historical data. Levels above 0.98m 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.
