Mill Beck

A stream near Yarlside, Westmorland and Furness. No gauge of its own: what the river map and the banked data say about it.

Mill Beck is a stream on Ordnance Survey’s river map near Yarlside, Westmorland and Furness, with about 5.4 km of mapped channel. On the map it flows into Low Level Beck, which flows on into Walney Channel and out to the sea.

Next gauge downstream

None before the water reaches tidal water, about 1.0 km downstream. Below that, gauges read the tide.

Storm overflows on Mill Beck

A status says whether an overflow is discharging now, never how much or why. A monitor that is offline or has not reported is not “not discharging”. Sewage in Britain’s rivers →

A sample is taken on a date; it says nothing about the water today. A sample below an overflow does not by itself show where anything in it came from.

What this page can and cannot tell you

Its line, its name and where it flows come from Ordnance Survey’s river map (OS Open Rivers, edition 2026-04), which leaves out many small streams, ditches and culverts. “Flows into” is the map’s word: a channel that is not on the map is not shown here, which does not mean it is not there.
No gauge measures Mill Beck itself, so its own level is not known here.
Storm overflows are listed only where the river map places them on this stream; an overflow it could not place is not counted.
Water samples are England’s only (the Environment Agency’s archive), placed where the map can place their sampling point.
Nothing on this page says whether any place floods. For an address, see its postcode page.
