Hogsmill eels get a helping hand


Clattern Bridge eel tiles

Working in close partnership with the Zoological Society of London and Thames Anglers’ Conservancy, we’ve recently been delivering a small but important project to improve eel passage on the little Hogsmill River through Kingston.

Like the Wandle and the Mole, the Hogsmill should be an important stronghold for eels, which are now considered critically endangered. But recent monitoring efforts by volunteers from Kingston University have found no elvers in the river at all, leading to suspicions that they find the concrete sill under Kingston’s historic Clattern Bridge an impassable barrier.

By installing specially-designed eel tiles, we hope we’ve now solved this problem, and that eels will now be found swimming up the Hogsmill.
