River Alham

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

The River Alham is a stream on Ordnance Survey’s river map near Alhampton, Somerset, with about 18 km of mapped channel. On the map it flows into the River Brue, which flows on into the River Parrett and out to the sea.

Next gauge downstream

Lovington on the River Brue, about 2.5 km along the river below where the River Alham ends on the map.

After that, Clyse Hole, about 16 km along the river.

No gauge measures the River Alham 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.

Storm overflows on the River Alham

1 storm overflow is placed on this stream on the river map. Each status is the water company’s own monitor.

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 →

Water-sampling points on the River Alham

9 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.
