FOR almost two years Whitehaven's harbour water has turned to a dark orange and brown colour. 

The colour change initially began to affect the water in the Queen's Dock area, however, this has begun to spread further with water surrounding the Lime Tongue and South Harbour becoming more discoloured. 

Whitehaven's inner harbour is separated from the outer harbour by lock gates, which open and close to let boats and yachts pass through. 

Depending on the weather and the way of the tides, discolouration can sometimes be noticed around the outer harbour towards the North and West Pier Lighthouses. 

However, this is more diluted than that in the inner harbour and looks less discoloured. 

The issue has been ongoing for almost two years, with the problem first arising in late 2022. 

It is not yet known what the specific cause of the discolouration in the water is, however, it is thought to be linked to the former mine works that were once a bustling trade in Whitehaven and the surrounding areas. 

Organisations like Network Rail and the Environment Agency are working on tests to try and detect the specific cause of the colour change.

It is thought that the discoloured water is entering the harbour through the Queen's Dock area as it is partly connected to the Bransty Railway tunnel. 

Whitehaven Harbour Commissioners are currently working with Copeland MP Trudy Harrison to see what can be done about the ongoing problem. 

Mrs Harrison said earlier this year: “There remains some uncertainly as to the exact cause, and there was general agreement the brown water could be down to multiple causes.

"Therefore the continued visual and geo-physical monitoring will be required with results updated to the group in coming weeks.

Regular meetings are scheduled between the relevant parties to provide updates. 

The Environment Agency has said that the water is not harmful to the health of humans or animals despite its appearance. 

Deanne Shallcross, CEO of Whitehaven Harbour Commissioners, previously said: "We are pleased to be part of the multi-agency task force and look forward to further conversations, meetings and working together for the benefit of our wonderful 400-year-old harbour, its users and the town as a whole."
