Volunteers find double number of eel barriers on River Mole

European eels face more than double the number of barriers as had previously been recorded when travelling along the River Mole and its tributary rivers, a pilot conservation project has found.

Volunteers trained by the South East Rivers Trust (SERT) as part of the Thames Catchment Community Eels Project found 119 impediments – such as weirs, sluices and culverts – 66 of which were new to existing data.

Thames Catchment Community Eels Project

We’re eel-y excited to announce that Thames Rivers Trust in partnership with the South East Rivers Trust, Action for the River Kennet, and Thames21, have been successful in gaining funding to aid the long-term survival of the European eel.

Eels have a spectacular and complex life cycle! European eels spend most of their lives living in Europe’s rivers, including here in the UK. When they are ready to spawn they migrate more than 6,000km across the Atlantic to the Sargasso Sea, where their lifecycle begins again.

Once hatched, the larvae make the incredible journey back across the ocean to our rivers, and develop into young eels, also known as elvers, before swimming upstream.

Action on sewage in rivers

Raw sewage is entering UK rivers on a horrifyingly regular basis, damaging our river ecosystems and putting public health at risk. In 2019 alone, untreated sewage poured into England’s rivers for an astounding 1.5 million hours, over the course of 200,000 separate incidents.

What’s really shocking is that, much of the time, this practice is completely legal.

Across the UK is a network of Combined Sewer Overflows (CSOs). These are essentially Victorian-era relief valves on the sewage treatment infrastructure. If sewage piping, or even a sewage treatment works, is becoming overwhelmed with sewage and rainwater, it is diverted and discharged into a nearby watercourse instead of backing up into homes.
