Sewage Threatens Rare Salmon in Hampshire Rivers
27 Feb
Summary
- Sewage spills into the River Itchen may endanger Atlantic salmon during their egg-laying period.
- MP Danny Chambers warned of potential 'ecological catastrophe' if waterways aren't protected.
- The Hampshire and Isle of Wight Wildlife Trust urged caution to protect salmon eggs.
Sewage continues to pour into Hampshire's River Itchen, raising urgent concerns for the future of Atlantic salmon. MP Danny Chambers has warned of an impending "ecological catastrophe" as the endangered fish, crucial to the local ecosystem, are currently laying eggs in the sensitive chalk stream.
At one monitoring location near Headbourne Worthy, sewage has been reported flowing for over 400 hours. In the River Meon, more than 500 sewage dumps have been confirmed this year alone. These incidents threaten the unique biodiversity of these rare habitats.
Conservationists from the Hampshire and Isle of Wight Wildlife Trust are urging people to stay out of the River Itchen. This measure is to protect the salmon eggs, which are laid in gravel nests called redds. The trust noted a record low of 133 adult salmon returning to spawn in 2022.
The government states it has enacted measures to clean up waterways and hold water companies accountable. Southern Water, in its 2025 Pollution Incident Reduction Plan, acknowledged progress in tackling pollution and is analyzing root causes.
