💧 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.

49 storm overflows are traced upstream of this gauge, the nearest 130 m away along the river. 0 report discharging now, 47 report not discharging, and for 2 the monitor is offline or has not reported, so their status is not known.

2 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 →

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

Station flow derived from ADCP to replace previous electromagnetic and earlier velocity area stations in a slow responding rural catchment.

More detail

The catchment

Low relief catchment, moderate in headwaters. Tributaries rise on Magnesian Limestone, then traverse outcrop of Sherwood Sandstone. Lower reaches underlain by alluvium and Mercia Mudstone. A portion of the catchment is urban, with Mansfield in the headwaters. Otherwise land use is predominantly rural, arable farming.

The station

Originally velocity area station; electromagnetic gauge since 1982 in reach between two bridges and trapezoidal flood banks. Primary recording switched to Side-looking ADVM 4th July 2015 then to a bed mounted ADVM from 23rd Jan 2018. Flood flows fully contained.

How it measures flow

Original velocity area station was prone to severe seasonal weed growth and unstable ratings due to variable backwater effect. Over-bank flow occurring above 1.9m inundating a wide floodplain. In Jan 1982 the channel was re-graded and rating relationship altered considerably; levels fell and velocities increased. The flow series from pre and post the electromagnetic gauge (installed 1982) are not consistent. 1982-1994 shows good agreement to spot flow gaugings. 1994-2015 shows under-recording of flows with a bias of -6.7%. ADCP installed September 2014 to run in parallel to electromagnetics during calibration. Primary flow derived from ADCP after lightning strike rendered electromagnetic gauge inoperable in November 2015.

Flow regime

Generally slow response. Reservoir(s) in the catchment together with significant abstraction and effluent returns affect runoff.

The flow record

Pre-electromagnetic data (1965-82) removed as unreliable. Gauge failed in 2000 floods but peak flow was gauged. Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9).

Frequently asked questions

Is the River Idle at Mattersey flooding today?

The current level is 0.87m, which is within the typical range of 0.55 to 2.70m. Flooding is unlikely at this level.

Is the river level rising or falling at Mattersey?

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 Idle at Mattersey?

The typical range at this station is 0.55m to 2.70m, based on Environment Agency historical data. Levels above 2.70m 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.
