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 based in the chalk dominated upper catchment of the River Kennet.

More detail

The catchment

A Chalk catchment with some Clay-with-Flints cover in the lower catchment. It is predominantly rural with Marlborough, a market town, close to outfall. The runoff is low and overall is a baseflow dominated catchment. The hydrological catchment is smaller than the topographical catchment.

The station

Crump weir, 6.1m broad, with crest-tapping plus a broad-crested side weir for high flows. Fish passage baffles fitted to back face of the main crump weir in 2014.

How it measures flow

Full range and only subject to occasional drowning. One peak flow rating applied across period of record. Rating curve currently underestimates flows beyond 0.442m when the rating should be based on a crump and broad crested weir.

Flow regime

Baseflow dominated regime where runoff is low. The hydrological catchment is smaller than the topographical catchment; some diminution (reduction) in flow also results from gw abstraction.

The flow record

Full period of record peak flow data reviewed and released in September 2023 (WINFAP Files v12).

Frequently asked questions

Is the River Kennet at Marlborough flooding today?

The current level is 0.06m, which is within the typical range of 0.04 to 0.63m. Flooding is unlikely at this level.

Is the river level rising or falling at Marlborough?

Based on the most recent readings, the level is currently steady. The chart above shows the last 7 days of measurements, updated roughly every 15 minutes.

What is a normal level for the River Kennet at Marlborough?

The typical range at this station is 0.04m to 0.63m, based on Environment Agency historical data. Levels above 0.63m are higher than usually seen and may indicate a flood risk.

How often is this river level data updated?

Readings are taken by the Environment Agency gauge roughly every 15 minutes and FloodRadar refreshes its data continuously, so the level shown is normally less than an hour old.
