River Len

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

The River Len is a stream on Ordnance Survey’s river map near Maidstone, Kent, with about 16 km of mapped channel. On the map it flows into the River Medway and out to the sea.

Next gauge downstream

Maidstone on the River Medway, about 80 m along the river below where the River Len ends on the map.

After that, ALLINGTON USGS, about 2.4 km along the river.

No gauge measures the River Len 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 Len

9 storm overflows are 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 Len

7 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.
