Work starts on the country's
largest fish pass
Jackson has started construction of what will be the largest fish pass in the country when it is completed in 2023.
Working on behalf of the Environment Agency (EA), the Jackson team is building the structure at Holme Sluices on the River Trent near the Nottinghamshire village of Colwick.
While the sluices form an important large-scale flood defence, they also act as a barrier to fish migrating upstream. The new fish pass will help improve the biodiversity of the River Trent catchment, allowing species to travel further into the Midlands river network.

When completed, the fish pass will be 200m long, 6m wide and 6m deep, and broken up into a series of 21 ascending chambers into which the water will flow through narrow slots. All fish species will be able to swim through these slots and rest in the next chamber above before continuing their journey up the pass and into the river above.
It will also include an eel pass to help support the critically endangered European Eel, as well as a public viewing platform, so people can try and spot fish as they make their way through the pass.
Councillors along with other dignitaries, including EA Area Director Louise Cresswell and local MP Tom Randall, visited the site last Friday to hold a ground-breaking ceremony to mark the beginning of the works

'It is wonderful that work is underway on this landmark scheme. This is an important and exciting project designed to boost biodiversity in the River Trent and Jackson is delighted to be working alongside the Environment Agency on the scheme.'
