Bowston weir removal

Project summary

Edit project overview to modify the project summary.

Bowston weir is the first weir to be removed on the River Kent Site of Special Scientific Interest and Special Area of Conservation (SSSI/SAC). Bowston weir removal forms part of the Cumbria River Restoration Strategy (CRRS) which aims to restore the three Cumbrian SSSI/SAC rivers to their natural form and function and help them achieve Favourable Condition.

Monitoring surveys and results

This case study hasn’t got any Monitoring survey and results, you can add some by editing the project overview.

Lessons learnt

Edit project overview to modify the lessons learnt.

SCRT created a Local Community Engagement Plan with local representatives which explained how, what and when we would communicate with local stakeholders and the public. This was extremely effective in setting out our engagement responsibilities and ensured a standardised approached to our communications.
