The Rediscovering the River Colne programme aims to enhance and revive the river for both nature and people, allowing visitors of all ages to once again enjoy and value this key natural asset. We plan to do this by creating a healthy river corridor with cleaner water and restored habitats, so that native mammals, birds, fish, insects and plants can return to the river and its banks.

Before we began our work, we extensively assessed, investigated and modelled a number of key sites on the north and south sides of the river (northern section from Knutsford Playing Fields to Waterfield Recreational Area; southern section from Oxhey Park to Lairage land).


We are also continually consulting with key groups and local people to better understand how we can achieve our collective goals. Click here for an overview of the history and key river issues.

For the northern sites, we now have reports that detail the key issues faced in each section with recommendations on the key works that will be conducted – please click on the links below to find out more:
