Worm Brook

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

Worm Brook is a stream on Ordnance Survey’s river map near Kilpeck, County of Herefordshire, with about 13 km of mapped channel. On the map it flows into the River Dore, which flows on into Afon Mynwy (River Monnow), then Afon Gwy (River Wye), then Afon Hafren (River Severn) and out to the sea.

Next gauge downstream

Grosmont Rhosllwyn River Station on Afon Mynwy (River Monnow), about 6.2 km along the river below where Worm Brook ends on the map.

After that, Skenfrith River Station, about 16 km along the river.

No gauge measures Worm Brook 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.

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 →

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 Worm Brook 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.
