May 2025 update

Project timeline

Construction is planned between Winter 2026 and Summer 2028, subject to funding and approval.

Preparation works, scoping the locations where works are to take place, and design, have already begun. The project will likely include vegetation removal, topping up low spots on embankments, access improvements to carry out routine maintenance, and restoring banks that have eroded in channel.

Work completed so far

A LiDAR topographical, and ecological survey have been completed to help us understand the work needed.

A LiDAR survey (Light Detection and Ranging) collects highly accurate, three-dimensional data of the Earth's surface. The data collected supports project development by identifying 'low spots' and other features of the banks and enabling our project team to identify priority areas for the project works.

Geophysical surveys have been carried out to inform our understanding of local archaeology. Ecological surveys are ongoing to help us understand what species are present and what we can do to protect and improve their populations. To date, bat and owl surveys have been completed.

What's next

• Our project team will be working on developing the outline design incorporating elements to maintain the standard of service by stabilising banks and to improve maintenance by widening the banks and adding access routes where feasible.
• Analysis of the LiDAR results will allow the project team to provide design solutions and forecast costs to bring the banks back to the previous standard of service.
• Ecology field work including water vole, otter, newt, and breeding bird surveys.

Impact on local residents

Surveyors may be visible along embankments and nearby fields Monday to Friday, 08:00–18:00.
