Works are nearly complete on a ‘game changing’ river project along one of London’s most important rivers. Project leaders are now calling on volunteers to undertake conservation work along the river banks to help “nature return” to that stretch of the River Wandle. The South East Rivers Trust (SERT) has been carrying out works on the Mitcham stretch of the River Wandle for the past 10 weeks.

The project, carried out by a group of partners including landowners Sutton Council, aims to improve the health of the rare chalk stream and re-naturalise the area for public use. The project is focused on lowering the Goat Bridge Weir in Mitcham , which previously restricted about 500 metres of river, creating conditions more akin to a lake. This meant the flow of the river was obstructed, leading to stagnant pools of water where pollution thrives.

During a visit to the site last week, Hogan told MyLondon of some of the surprising things the project team had found whilst working in the river. Hogan said: “We’ve found a lawnmower, a couple of fridges and even a motorbike in there.

This stretch of the river was in a pretty poor state.” The river's course has been diverted around the weir throughout the 14-week project and is expected to return to its normal path .
