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 3.3 km away along the river. 0 report discharging now, 3 report not discharging.

2 more within 6 km whose connection is not known.
7 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. Sewage & storm overflows →
🌊 Fairly flashyResponds fairly quickly to rain, with moderate baseflow between events.
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
Narrow, linear, north-south trending catchment draining southern flank of Dartmoor Granite. Headwaters in plateau-like moorland; main river section in steep, deeply incised valley with short tributaries. Off granite, Devonian Slates widely blanketed with river gravel and alluvium. Responsive catchment. Land-use is moorland in the upper catchment and predominantly low-grade agriculture elsewhere. Catchment includes town of Ivybridge. No major catchment changes.
The station
Velocity area station with low level Flat V control. Control is approximately 9.4m wide and unchanged. Station is located a few hundred metres east of the village of Ermington.
How it measures flow
Stony river bed. Cableway present. Good station, minimal bypassing and well rated with reasonable fit to available gaugings. Recent investigations suggest backing-up when high flow coincides with high tide. Mutliple peak flow ratings accross period of record.
Flow regime
Significant flow modifications by abstractions and diversions for public water supply and sewage effluent returns from Ivybridge.
The flow record
Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9). Rating reviewed in 2022 and data reprocessed for the full period of record.

Frequently asked questions
Is ERMINGTON flooding today?
The latest recorded level is 2.80m3/s. Compare it with the recent history on the chart above to judge whether levels are unusually high.
Is the river level rising or falling at ERMINGTON?
Based on the most recent readings, the level is currently falling. The chart above shows the last 12 hours of measurements by default (up to 7 days), updated roughly every 15 minutes.
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.
