How is South West Water helping Atlantic salmon populations?

South West Water is adding over 1,000 tonnes of gravel to the River Teign to restore spawning habitats for salmon.

What impact has the gravel augmentation had on River Teign salmon?

The gravel addition has recreated near-original conditions, allowing salmon and trout to access more upstream spawning grounds.

Why are salmon populations declining in Devon and Cornwall?

Factors include reduced gravel supply due to reservoirs and water pollution, with no principal salmon rivers currently supporting sustainable populations.

Efforts to bolster Atlantic salmon populations have involved the addition of over 1,000 tonnes of gravel to the River Teign since 2015. This extensive project, spanning 11 years, has focused on restoring vital spawning habitats below Fernworthy Reservoir.

The intervention aims to counteract the impact of dams and reservoirs, which reduce natural gravel supply to downstream spawning grounds. Experts report that salmon and trout are already benefiting, utilizing the improved habitats and accessing areas further upriver than previously possible.

While this gravel augmentation represents a significant step, some conservationists emphasize the need for broader action, including reducing water pollution from sources like sewage, to ensure the long-term sustainability of salmon populations in the region.
