South East Rivers Trust (& the Wandle Trust)

Thames Catchment Community Eels Project is a partnership, led by Thames Rivers Trust, with Action for the River Kennet, South East Rivers Trust and Thames21.  We are working together to aid the long-term survival of the European eel.  Through new citizen science monitoring, we will be collecting and analysing robust data, which can then be used to make strategic decisions for future eel recovery projects. 

Our aim is to raise the profile of this Critically Endangered fish through education and engagement with local schools and communities.

Education Sessions

The South East Rivers Trust is delivering sessions about the local river and the European eel in the River Mole area. We are now offering primary schools:

  • FREE online assemblies
  • FREE online workshops
  • FREE classroom workshops
  • FREE river sessions at Grattons Park, Crawley.

We are taking bookings for the autumn term. Sessions are linked to ‘Living things and their habitats’ and provide a valuable contribution to a range of topics such as ‘Rivers‘ or ‘Flow‘. 

It’s fun and it’s free!

As well as education sessions, amazing educational resources are available and can be found here.

Obstacles in rivers are major factors contributing to the dramatic decline of the European Eel but there are huge gaps in our knowledge of where they are and how they impact eel migration.

We’re working with our fantastic volunteer ObstacEELS surveyors to map obstacles to eel migration across the Mole Catchment. The data they collect will enable a strategic approach to future eel projects along the Mole which will improve the river for this critically endangered species.

Community Talks and Guided Walks

 The South East Rivers Trust is also looking to deliver a number of guided walks and talks with local community groups in the Mole catchment.

We will introduce the species and talk about its incredible life cycle, before covering some of the threats it faces and what’s being done to help it. It is a great opportunity to raise awareness about the plight of the eel which is an incredibly fascinating creature.

If you’d like us to come and talk to your community group or run a guided walk with you, please email

Elver Migration Monitoring

We’re working with an amazing bunch of volunteers to monitor the migration of young eels (elvers) on the River Ember, a side branch of the River Mole.

Recruitment of young eels has fallen significantly over the last 40 years so this monitoring is incredibly important to help them survive and thrive. The data collected at this site feeds into a project spanning the Thames, coordinated by ZSL. It provides essential information which helps prioritise and plan work across London and beyond to help these endangered creatures.

Between April and September our team of volunteers are

  • Checking the eel trap regularly
  • Counting, measuring and releasing any eels found
  • Uploading records to the ZSL website.

This gives us data on the number of young joining the adult population and can highlight the impact of barriers, one of the principle threats to eels in freshwater.
