On other watercourses

These gauges are filed under the Deben, but the river map places them on another watercourse, so they are not in the Deben’s order above.

Debenhamon The GullsDebenham0.26 mASD 31m agoNormal—
Its water joins the Deben above Brandeston, 10.5 km by river.

Stations are listed from source to mouth as the water flows, traced on the river map (OS Open Rivers) and the Environment Agency’s own links between its gauges. A distance “by river” is along the river, and is shown only where the map traces the path.

Gauged tributaries

Streams and rivers with a gauge whose water joins the Deben above one of its gauges, from the source down. The river map knows where gauges are, not every stream, so a tributary without a gauge is not listed here.

1 gauged tributary, 1 gauge

The Gulls name from the river map

Joins the Deben above Brandeston, its highest gauge, no more than 10.5 km by river above Brandeston.

Debenham0.26 mASD 31m agoNormal

Its water passes every gauge on the Deben, from Brandeston down.

Where the Deben goes

Below Brandeston, its water next reaches Woodbridge (distance by river not measured).

Tributaries and where they join are traced on the river map (OS Open Rivers, edition 2026-04) and the Environment Agency’s links between its gauges. The map holds distances between gauges, not the junctions themselves, so a junction is placed between two gauges, and no further up than the tributary’s own lowest gauge.

Storm overflows upstream

1 storm overflow is traced upstream of Brandeston, the Deben’s lowest gauge on the river map: on the Deben itself, on its gauged tributaries, and on smaller streams that join above there.

Official figures for 2025, for the overflow traced upstream of Brandeston: 5 spills over 24 hours.

Each overflow is listed in the stretch above the first gauge its water reaches, from the source down, as on the Gauges tab. A stretch of the Deben includes the smaller streams that join it there.

Above Brandeston, the Deben’s highest gauge1 overflow

A status is the water company’s own monitor: it says whether an overflow is discharging, never how much or why, and a spill does not by itself explain a change in a river level. A status older than two hours is shown as unknown. Annual figures are the official returns: 12/24-hour spills for England and Wales, overflow events for Scotland (Scottish Water counts differently, so the two cannot be compared). “No data” means the monitor produced no usable data that year, not zero. Overflows are placed on OS Open Rivers (edition 2026-04), which leaves out many small channels: an overflow the map cannot place may still drain here.

Water samples

Dated samples taken by the Environment Agency, not live readings. Results are published days to months after the sample is taken, and many points are sampled only a few times a year, or have not been sampled for years.

21 sampling points on the River Deben and the streams that join it above Brandeston, and below it. 3 have a sample from the last 12 months; 5 have any sample banked. Listed from the source down, grouped by the next gauge each one's water reaches.

Distances are along the river to the gauge named. England's samples only.

FloodRadar does not grade these results: there is no overall score, and official river classifications are a separate dataset. A sample taken downstream of an overflow does not by itself show where anything in it came from. River connections and distances are traced on OS Open Rivers (edition 2026-04), which leaves out many small channels.
