Sail Beck

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

Sail Beck is a stream on Ordnance Survey’s river map near Rosthwaite, Cumberland, with about 730 m of mapped channel. On the map it flows into the River Liza, which flows on into the River Ehen and out to the sea.

Next gauge downstream

Bleach Green Weir on the River Ehen, about 13 km along the river below where Sail Beck ends on the map.

After that, Egremont, about 28 km along the river.

No gauge measures Sail Beck itself. A gauge downstream shows water that has already passed it, mixed with everything else that has joined on the way, so it says nothing exact about this stream.

Water-sampling points on Sail Beck

1 Environment Agency sampling point is placed on this stream. These are dated samples taken by hand, not live readings, and FloodRadar does not grade them.

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 Sail Beck itself, so its own level is not known here.
No storm overflow is placed on this stream on the river map. That is not the same as none: the map cannot place every overflow.
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.
