We are seeking volunteers to assist with eel monitoring throughout September as part of the Conserving Slimy Wrigglers Project.

Volunteers will work with staff from HMWT, the Environment Agency or Lea Valley Regional Park Authority to monitor eel numbers on two eel passes in Lea Valley Regional Park. Volunteers must be physically fit and able to work in water. Full training will be provided.


In 2016 HMWT in partnership with the Environment Agency and Lea Valley Regional Park Authority installed two eel passes on a flood defence weir in the River Lea as part of the Conserving Slimy Wrigglers Project. Eels are a critically endangered species and barriers to migration are considered one of the main reasons for a 95% decline in global numbers. Through September 2017 the eel passes installed by the partnership will be monitored continuously to make sure they are working and also to gather vital data on eel populations in the River Lea. Monitoring involves setting special net traps onto the two passes which must be checked and reset every three days. We are seeking volunteers to give 2-3 hours of their time on mornings that suit them throughout September.
