Improving ecology in low flow conditions through river restoration on the River Gadder
The Water Industry National Environment Programme (WINEP) is a cornerstone of environmental regulation in England, setting out the actions water companies must deliver to meet statutory obligations and contribute to wider environmental goals. AMP7, which covered 1 April 2020 to 31 March 2025, represented one of the most ambitious WINEP cycles to date, with over 11,900 actions aimed at improving water quality, protecting biodiversity, and supporting sustainable water resources. The case study below provides an example of one of the completed AMP7 projects.
To improve the habitat for ecology in low flow conditions river restoration was carried out on a stretch of the River Gadder adjacent to Oxburgh Hall. The aim of this was to increase flow diversity and velocity.
Anglian Water worked with the National Trust at the Oxburgh Estate to complete the work. Several in-channel restoration techniques were utilised along with creation of a new channel to bypass a historic culvert. Woody and gravel berms (raised shelves) were deployed at regular intervals to narrow the channel and increase flow speed. Sections of the riverbed were augmented with gravel to restore the river to a more natural state. The old channel was left as a backwater habitat for fish.
In addition to work on the Oxburgh Estate, Anglian Water completed several other river restoration schemes in East Anglia
