River Fynn

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

The River Fynn is a stream on Ordnance Survey’s river map near Playford, Suffolk, with about 13 km of mapped channel. On the map it flows into Martlesham Creek, which flows on into the River Deben and out to the sea.

Next gauge downstream

None before the water reaches tidal water, about 10 m downstream. Below that, gauges read the tide.

Storm overflows on the River Fynn

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 →

Water-sampling points on the River Fynn

9 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.
