From South West Water:

In addition to supplying your water and sewerage services, South West Water have a responsibility to improve the environment. The Water Industry National Environment Programme (WINEP) holds us accountable on how we’re doing. It also tells us what sort of schemes we should be completing to fulfil our obligations.

Following consultation with the Environment Agency, it was found that the River Tamar plays a vital role for the highly protected allis shad. The river hosts the only spawning site for this fish in the UK. Unfortunately, the Gunnislake Weir presents a huge obstacle for the fish on their journey to this site. That’s why we’re proposing to construct a new fish pass there.

Although there’s already a fish pass on the Cornish bank at Gunnislake Weir, it’s only considered effective for the passage of salmon. The new fish pass would be useable by allis shad, as well as smelt, trout, salmon and eels.

We’d like to tell you more about this scheme, so we’re holding an information event at Gunnislake Village Hall, Fore Street on Tuesday 20 June 2023 between 2pm and 6pm, you can drop in at any time. Members of the project team will be there to answer your questions and discuss any concerns you might have about the scheme.
