3. Shipley Tilting Gate (ARPHA)

Themes: Fisheries; Natural rivers


  • 2. All constraints and risks to the establishment of thriving fish populations (comprising an appropriate range of species) within the Adur and Ouse systems will be identified.
  • 10. Identify, research and find funding sources for re-naturalisation projects throughout the catchment.

Project description

One of the 12 priority sites for appraisal and improvement in the Adur Restoration of Physical Habitats (ARPHA) strategy. 

Shipley tilting gate is an Environment Agency owned and maintained structure on the Knepp estate, which was preventing fish passage and impounding the river upstream.  It existed to maintain water levels at a certain depth upstream and was acting as a barrier to coarse fish and elvers. An associated issue was that the channel dried out downstream of the structure, when flow in the river was low, and the dry channel became clogged with vegetation.

The gate has now been removed and the clay banks have been stabilised with brushwood terracing. This not only removed the  barrier to fish passage but it has also helped restore natural river processes which will be beneficial to wider biodiversity as whole.
