THOUSANDS of dead fish can be seen in what remains of Colt Crag Reservoir.

Concerns have been raised about the condition of the reservoir, on the A68 near Barrasford, which is almost dry.

Colt Crag forms part of a series of reservoirs along the A68 which are connected by tunnels and aqueducts from Catcleugh Reservoir to Whittle Dene.

In pictures seen by the Courant, dead fish litter the shoreline.

Northumbrian Water has now said it plans to restock the reservoir with fish once it returns to its normal level.

A spokesperson for the company said: “Colt Crag reservoir was partially reduced over the summer to support essential engineering works within the valve tower.

“A lack of rainfall in the area has also contributed to the water level being lower than normal.

“We’re aware that this has had an impact on the fish within the reservoir, and that some have sadly died because of the low water levels and the lack of dissolved oxygen in the remaining water. We’re extremely sorry that this has happened.

“We looked at the possibility of moving the fish – or further aerating the water – but this would have been too dangerous at the time. However, we will continue to assess the situation and if it is at all possible we will endeavour to proactively manage the water quality.

“We are working with the Environment Agency in monitoring Colt Crag and we will continue to visit the site on a daily basis. We will restock the reservoir with fish once it returns to its normal level.”
