The River Deben is a tidal estuary in Suffolk, flowing through largely unspoilt countryside for nearly 25 miles from its source near Debenham to the North Sea at Felixstowe Ferry. The Deben is tidal for about 13 miles, from Bromeswell, just upstream from Woodbridge.

Membership of the RIVER DEBEN ASSOCIATION (RDA) enables individuals and organisations to influence what happens on and along this beautiful river. The association was established over 20 years ago to give a forum for issues relating to the wellbeing of the river.  In 1997 it took an active part in voicing concerns over the potential adverse impact of commercial development of the former Bentwaters airbase.  Since then it has been engaged in a wide range of projects, and now has around 700 members.

The Association works closely with local authorities and statutory organisations through its representation on the River Deben Partnership, of which the RDA is a founding member.
