30. Denham Weirs Eel Passage Improvements

Aim: Improve wildlife corridors

Water body: Rivers Colne & Frays
Project description

Weir modification to provide eel passage.

Three barriers were identified: one on the River Colne at Denham Lodge in New Denham and in Denham Country Park where the River Frays and Colne meet. Eel Passes were successfully installed, to allow eels to negotiate the weirs in all three of these positions. Groundwork South worked in partnership with Affinity Water, Thames Water and The Environment Agency (with additional funding from Grundon) to resolve barriers to the migration of European Eels.
