Rattle Stream

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

Rattle Stream is a stream on Ordnance Survey’s river map near Westham, East Sussex, with about 1.1 km of mapped channel. On the map it flows into Mountney Sewer, which flows on into East Langney Sewer, then Langney Sewer, then Salt Haven; beyond that the map has a gap, so where it goes next is not known.

Next gauge downstream

Pevensey on Salt Haven, about 5.1 km along the river below where Rattle Stream ends on the map.

No gauge measures Rattle Stream 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 Rattle Stream

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 →

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 Rattle Stream 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.
No water-sampling point with a banked sample is placed on this stream. Only England’s samples are banked, and only where the map can place their sampling point.
Nothing on this page says whether any place floods. For an address, see its postcode page.
