Crane Brook

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

Crane Brook is a stream on Ordnance Survey’s river map near Wilsley Green, Kent, with about 5.6 km of mapped channel. On the map it flows into Hammer Stream, which flows on into the River Beult, then the River Medway and out to the sea.

Next gauge downstream

Stilebridge on the River Beult, about 23 km along the river below where Crane Brook ends on the map.

After that, Teston, about 37 km along the river.

No gauge measures Crane 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 Crane 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.
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.
