River Colne

This catchment consists of the River Colne, Stambourne Brook, Toppesfield Brook, Pebmarsh Brook and Salary Brook. The Colne has been split into 3 sections and covers a total length of 50km. Stambourne (6km in length) and Toppesfield Brook (6km in length) flow into the middle section of the Colne (identified as Great Yeldham to Doe’s Corner), Pebmarsh (5km in length) and Salary Brook (15km in length) flow into the downstream section (identified as downstream of Doe’s Corner). Bourne Brook also flows into the River Colne.

This map shows the current projects; potential, in progress and completed, for the River Colne.

River Colne data on the NBN Atlas

Essex Wildlife Trust Biological Records Centre received funding from the Environment Agency in late 2017 to digitise river corridor survey data for the River Colne and a number of tributaries along the catchment.

The River Colne is an asset for wildlife and water through Essex, however it is known to have low flows and low dissolved oxygen levels at certain times of the year. This can affect fish, insects and other aquatic wildlife. Planting trees along the river can help to reduce these impacts by creating shading which results in cooler water temperatures and higher dissolved oxygen levels.

Darren Tansley, Essex Wildlife Trust's Water for Wildlife Officer, worked with landowners in Sible Hedingham to improve a lake that was previously a carp fishing lake.

The lake is no longer fished and the carp have been removed and is now left to become a wildlife area. The quality of the water within the lake is poor
