8. Hertford Weirs - Enhancing Fish Passage
Theme: Ecology and biodiversity
- Have thriving and spawning fish populations
- Improve the river’s morphology
This project aims to improve fish and eel passage along the River Lea and River Beane through Hertford.
Hertfordshire's rivers have been modified historically to serve past industry, transport and flood defence schemes. At many points along the River Lea and its tributaries, weirs and other man-made structures have been introduced.
These cause major problems for fish and eel passage, preventing them from easily moving upstream and downstream. They also cause the river directly upstream to become impounded, resulting in sluggish flows, excess siltation and habitat degradation that impacts more widely on biodiversity.
The Environment Agency, in partnership with Countryside Management Service and East Herts District Council, commissioned a Feasibility Study in 2018 to identify options for adapting six weirs through Hertford to address these issues.
After public consultation in autumn 2018, preferred options for each of the six weirs were identified. Outline designs are being prepared by JBA Consulting in early 2019 and costed for implementation.
Further funding is sought to develop the outline plans into detailed designs, with a view to start implementing these from 2020/21.
