💧 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.

2 storm overflows are traced upstream of this gauge, the nearest 5.6 km away along the river. 0 report discharging now, 2 report not discharging.

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

Compound Crump weir.

More detail

The catchment

River drains coastal hills of West Cornwall; relief is quite subdued, and rocks outcropping are shales and sandstones of Carboniferous Culm Measures. Land use is wholly rural with some artificially induced vegetation, moorland and low-grade agriculture. Impoundment of the Tamar Lakes.

The station

Compound Crump profile weir, total crest length 11m.

How it measures flow

Piers submerge around 1.65m. Drowning occurs when stage > 0.6m, but non-modular flows can be gauged from the footbridge. Evidence of hysteresis in rating due to the size of the downstream flood plain. One peak flow rating applied across period of record. Above piers (>1.65m), theoretical within pier rating extrapolated. Transit time of flight installed in 10/2013 and used to apply a new high flow limb for the POR in 2015.

Flow regime

Unusual flood response, not indicative of upper Tamar conditions. Flows substantially modified by the impoundment of the Tamar Lakes 15km u/s. Runoff also reduced by public water supply abstraction.

The flow record

Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9).

Frequently asked questions

Is the River Tamar at Crowford Bridge flooding today?

The current level is 0.22m, which is within the typical range of 0.08 to 1.40m. Flooding is unlikely at this level.

Is the river level rising or falling at Crowford Bridge?

Based on the most recent readings, the level is currently falling slightly. 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. 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 Tamar at Crowford Bridge?

The typical range at this station is 0.08m to 1.40m, based on Environment Agency historical data. Levels above 1.40m 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.
