River Deben Estuary Tide mills at Woodbridge have operated off the tide from the river Deben since at least 1170. The present mill, built in 1793, is producing stone ground wholemeal flour in the traditional way. It marks the point from which the River Deben flows into the
Deben Estuary. In 2009, the Deben Estuary Partnership was developed to enable the local communities to have an input into complex and increasingly important issues that will be crucial for the River Deben and the surrounding estuary area. In 2015, the Deben Estuary Plan was drawn up following feedback. The Deben Estuary is a
Special Protection Area and
Ramsar Site and within the
Suffolk Coast and Heaths Area of Outstanding Natural Beauty. Its significance arises from its over-wintering population of
avocets (
Recurvirostra avosetta). The estuary features shifting
sandbanks. Plant life is dominated by the
common reed (
Phragmites australis). The
salt marsh and intertidal mud-flats that occupy most of the area have the widest range of salt marsh flora in Suffolk. ==Water resource management==
