River Liza

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

The River Liza is a stream on Ordnance Survey’s river map near Rosthwaite, Cumberland, with about 10 km of mapped channel. On the map it flows into the River Ehen and out to the sea.

Next gauge downstream

Bleach Green Weir on the River Ehen, about 4.7 km along the river below where the River Liza ends on the map.

After that, Egremont, about 19 km along the river.

No gauge measures the River Liza 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 the River Liza

3 Environment Agency sampling points are 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 the River Liza 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.
