7. Lock Farm (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.
  • 19. The effects, on fish and fisheries, of restoring rivers to a more natural state will be clearly identified and taken into account in river restoration plans.

Project description

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

The Lock Farm Penstock controls the western arm of the river Adur. The lock structure just below the penstock is currently in a state of disrepair and inoperable as a navigational structure.  The structures currently act as a barrier to the migration of migratory and coarse fish and elvers.  They are also causing an impoundment, resulting in siltation, lack of flow variability and a lack of in channel and marginal vegetation.

There is potential here to modify the channel, perhaps using rock placement to create a series of weirs, and to undertake channel improvement and re-grading works. These options have yet to be costed up and funded.
