9. 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 for historic industry, transport and flood defence. 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 engagement in autumn 2018, preferred options for each of the six weirs were identified. Outline designs were then completed in early 2019, and further funding is now being sought to develop the outline plans into detailed designs and deliver the improvements.
