Diageo, has announced the completion of a new weir and fish pass installation, to help boost the sustainability of salmon and trout stocks, in the Speyside whisky region.

The new weir and fish pass in the River Dullan – part of the River Spey catchment, which is crucial to the Scotch whisky industry, is the result of a £550,000 investment and a collaboration with the Spey Fishery Board.

Diageo announces completion of new Speyside river management system

Diageo’s Mortlach Distillery and Dufftown Distillery, currently use water from the River Dullan for cooling in the distilling process, but the weir will bring environmental benefits to the whole Spey water catchment area which is home to 11 Diageo single malt distilleries.

The project, which has taken three and a half years to design and construct, replaces an outdated and damaged weir, and will significantly improve upstream biodiversity and increase the opportunity for spawning trout and salmon.

Commenting on the news, Lee Oliver, Environment Manager at Diageo, said: “The design of the new fish pass is a vast improvement on the old, damaged weir at Dufftown and takes into account free passage for all fish species as well as different flow conditions. We have worked closely with the Spey Fishery Board to develop a weir system that will benefit all river users and in turn the local community. I am delighted to see the project complete and look forward to monitoring the results on fish populations over the next few years.”

A similar, smaller scale project has also recently been completed on the Burn of Linkwood at Linkwood Distillery in Elgin, in the neighbouring River Lossie catchment.
