Catchment Character

🌊 Fairly flashy Responds 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.

About this gauge

Velocity area station with cableway and Flat V control.

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 1.23m3/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 rising. 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. Only about 0.5mm of rain has fallen nearby in the last 7 days, so the flow is being sustained mainly by groundwater. 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.

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.
