Environmental Protections for the River Deben

Posted on by

By Liz Hattan, RDA Vice Chair

We are so lucky to live near the River Deben – many of us enjoy sailing and kayaking on it, walking by it, or swimming in it. It’s also special for its wildlife and landscapes resulting in it being designated under international and domestic law to help conserve it.   

The Deben Estuary is designated under international law by the Ramsar Convention on Wetlands, and under domestic law (England and Wales) as a Special Protection Area, as well as a Site of Special Scientific Interest, and as part of the Suffolk and Essex Coasts and Heaths National Landscape (previously known as an Area of Outstanding Natural Beauty AONB).[1]  But why has the Estuary received such designations and why does it matter?  In summary, it is designated because of the Deben’s unique and invaluable biodiversity and special landscape features; by having such designations it makes it easier to protect and conserve the area, both legally and because it helps remind us all to take extra special care of it.[2]

Citizen Science – Fish Survey 2024

Report from the Third Fish Survey conducted by the RDA and the Institute of Fisheries Management July 2024  by Steve Colcough

Introduction by Julia Jones

For the past three years, 2022, 2023 and 2024  the RDA has supported annual fish surveys in partnership with the Institute of Fisheries Management, represented by Steve Colclough. From the RDA side, enthusiasm and leadership come from Richard Verrill who initiated this project and has reported on it both here and in the Deben Magazine.

The 2024 survey also involved Suffolk Wildlife Trust as a new sampling site was located in the area of saltmarsh adjacent to Martlesham Wilds. Writing for the Deben Magazine Richard described the method of operating in this new site — setting a winged Fyke net across the creek at low tide, as well as using the seine netting techniques deployed at Bawdsey and elsewhere. 

Juvenile fish come in with the tide to feed on the saltmarshes and then are caught on their way out, counted and released back into the river. The quantities of fish caught at Martlesham in the 2024 survey were very impressive and a good indicator of the health of that area of the river — as well as a reminder of the importance of the Deben saltmarshes.  

Over the 2022, 2023 and 2024 numbers of juvenile fish have been good and the project is attracting interest from scientists in other areas.

Water Quality Update

Swimmers enjoying the water at Waldringfield January 2025

There continues to be much local and national interest and activity about the water quality of the River Deben.  This interest has led to a huge increase in knowledge of what is going on where, but there remains much to learn.  Below is a personal perspective of where we are now and further activity.

Introduction  – “What is the Water Quality of The Deben?” and “Can I swim in the Deben?”

“What is the Water Quality of The Deben?” and “Can I swim in the Deben?” are questions that are often asked.

River Deben Swimming and the Elephant in the Room

This is an extended version of Ruth Leach’s article ‘The Deben Bluetits Swim Group’, published on The Deben #68. It’s written in her capacity as co-founder of the Save the Deben campaign group and contains an update on water quality. This topic is scheduled for panel discussion at the River Deben Association’s forthcoming AGM, April 24th 2024.

During the recent pandemic our lives were deconstructed in so many ways, ‘free time’ – that precious commodity, was suddenly in abundance for many of us. People reconnected with their natural environment and for those fortunate enough to be near a blue space the love affair with nature soon flourished. Continue reading →

Report from the Second Fish Survey conducted by the RDA and the Institute of Fisheries Management September 2023  

by Steve Colcough

A small group of RDA volunteers, led by Richard Verrill, have been working together with Steve Colcough from the Institute of Fisheries Management and others to collect up to date information about fish stocks in the Deben. RDA Journal readers will remember Richard’s report from August 2022 – Deben Fish Survey 2022 

Now, following a second sampling session from higher up the river, Steve Colcough has produced a formal report available here — River Deben fish surveys 2023. Continue reading →

Leave Only Ripples

By Matt Lis

“Leave only footprints. Take only memories” they say of walking in the countryside, for those of us who enjoy hours afloat I suppose that translates to “Leave only ripples” so how do we achieve that?

When Julia asked me to write an article on how boaters can reduce their impact on the Deben I wonder whether she appreciated the enormity of the topic. I will fail to answer all questions for all people but by focusing on just a few topics I can try to summarise those things in just one long article.
