💧 Storm overflows upstream of this gauge

None of the storm overflows FloodRadar holds is traced upstream of this gauge on the mapped river network. That is not the same as none: the map leaves out many small streams and culverts, so an overflow it cannot place may still drain here, and not every company publishes every overflow.

4 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

🌊 Steep & flashy Steep catchment sheds rain quickly — expect fast, sharp rises after heavy rain.

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

Velocity-area station 250 m upstream of Windermere lake; one of the four main lake tributaries.

More detail

The catchment

Steep, mountainous catchment rising to over 700m.

The station

Established Nov 1995 as a temporary site to monitor low flows. Timber bed control present 2004-2009, bridge-mounted radar installed 2018. Station good for low and medium flows, suspect at high flows. Troutbeck Bridge (EA station 735327) was approximately 1.2km upstream and recorded from June 1967 to April 1983 (possibly poor data quality).

How it measures flow

Originally, pressure sensor in river that lacked accuracy. Whole river section subject to extensive work (from 10/07/1997) in strengthening the banks and re-grading the bed. A low timber bed control installed 10/09/2004 to improve stability but still prone to rating change and hence not replaced when destroyed in Nov 2009 flood; subsequently fully open channel again. Significant gravel deposition through reach during storm Desmond, Dec 2015. Levels over 2m affected by bridge immediately upstream causing significant afflux and some out of bank flow. Very high Windermere lake levels can also influence levels. Mobile gravel bed at the site results in frequent rating changes. Top end ratings are very uncertain and inconsistent, with lack of high gaugings.

Flow regime

Very flashy.

The flow record

Flows not held before 01/07/2003 due to poor quality. Low flows remain poor quality until the control was installed. Quality improved since then but still affected by frequent bed movements and rating changes. Missing data July 2010, Jan-Feb 2011, Feb 2023 and Sept-Oct 2023 due to instrument faults.

Rain upstream

This gauge has no rain model of its own, but it usually follows Miller Bridge House: when about 6mm of rain falls near Miller Bridge House in 6h, this gauge usually starts rising about 2 hours later.

Recent rain upstream: 4.2mm/6h — approaching Miller Bridge House's usual trigger.

Frequently asked questions

Is the Trout Beck at Calgarth flooding today?

The current level is 0.71m, which is within the typical range of 0.22 to 1.50m. Flooding is unlikely at this level.

Is the river level rising or falling at Calgarth?

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.

What is a normal level for the Trout Beck at Calgarth?

The typical range at this station is 0.22m to 1.50m, based on Environment Agency historical data. Levels above 1.50m 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.
