Kent Water

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

Kent Water is a stream on Ordnance Survey’s river map near Cowden, Kent, with about 11 km of mapped channel. On the map it flows into the River Medway and out to the sea.

Next gauge downstream

Chafford on the River Medway, about 900 m along the river below where Kent Water ends on the map.

After that, Colliers Land Bridge, about 2.0 km along the river.

No gauge measures Kent Water 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 Kent Water

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 →

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 Kent Water 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.
