Project summary

Edit project overview to modify the project summary.

The Avon Barriers project is a partnership project between the Rivers & Fisheries Trust for Scotland (RAFTS), SEPA, South Lanarkshire Council and the Clyde River Foundation. It seeks to open up fish passage across two weirs on the Avon Water. The project is currently at the end of the feasibility & optioneering phase and is currently in a review period to select the best option for both weirs from those identified, to proceed to design and build.

This project has been funded through the Water Environment Fund (WEF) administered by SEPA on behalf of the Scottish Government, with contribution from South Lanarkshire Council. The project has been managed by RAFTS.

By opening up fish passage across these two weirs almost 35km of salmonid spawning habitat will be accessable, improving the regeneration of the Clyde catchment as a valuable salmon fishery.

For further information on the Water Environment Fund please visit: http://www.sepa.org.uk/water/water_environment_fund.aspx

For further information on the project please examine the individual barrier project pages for Fernegair Weir and Millheugh Weir.
