Marsh Dykes and Thamesmead

The Marsh Dykes and Thamesmead Catchment Improvement Group (MDTCIG) want to improve the water environment in the Woolwich, Erith and Thamesmead area. Our aim is to make the waterways healthier and more attractive for your community and wildlife. For this, we need your help to tell us what you care about the most, so this can shape the work we do.

Thousands of people live or work by these rivers, canals and lakes – we want to know what you like about them, and what you don’t.


About us

We are a group of organisations committed to creating healthy marshes in Erith, clean ponds on Shooters Hill and attractive canals in Thamesmead. The group is co-hosted by charities Thames21 and London Wildlife Trust.

We joined forces in 2016, and so far we have concentrated on running community events, such as removing plastic and other waste from canals and lakes in Thamesmead, and creating and enhancing green space such as installing 280m2 of floating reedbed in the Thamesmead canals and lakes.

The Marsh Dykes and Thamesmead Catchment

The catchment is the natural drainage area for rainfall between Erith Marshes in the east, Shooters Hill in the south and Woolwich in the west. All the water bodies we work on are highlighted in the map above.

We are creating a vision to lead the work of the MDTCIG

Our vision will spell out the core purpose of the MDTCIG. It will be our compass, to make sure we concentrate on projects that fit that purpose.


Why do we need your help?

With your input, we can make our vision relevant to your community and reflect what you care about. This will make sure our projects meet your needs, and create places for wildlife to thrive.


Please can you spend 5 minutes to give us your thoughts on the freshwater near you?

The survey is open for you to participate until 7th January 2019.


What happens next?

We will use the information you have provided to identify the priorities for our vision statement. We will draft vision statements and ask the community to vote on their preferred vision for the waterways in February 2019.
