River Somer

A stream near Midsomer Norton, Bath and North East Somerset. No gauge of its own: what the river map and the banked data say about it.

The River Somer is a stream on Ordnance Survey’s river map near Midsomer Norton, Bath and North East Somerset, with about 1.7 km of mapped channel. On the map it flows into Wellow Brook, which flows on into Midford Brook, then the River Avon and out to the sea.

Next gauge downstream

Wellow on Wellow Brook, about 9.5 km along the river below where the River Somer ends on the map.

After that, Midford, about 16 km along the river.

No gauge measures the River Somer 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 Somer

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 the River Somer 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.
