Anglers launch legal campaign to help Atlantic salmon on the River Eden
Ahead of World Fish Migration Day, a campaign was launched to help wild Atlantic salmon and other fish species migrate to and from their spawning grounds in the River Eden in Cumbria, UK. #BreakThroughCorbyWeir has been initiated by local anglers from the Yorkshire Fly Fisher’s Club, the Carlisle Angling Association and Fish Legal. The campaign’s objective is to ease fish migration at Corby Weir near Wetheral, which is a major obstacle for them in the highly protected river.
Corby Weir was built in just three months by the Environment Agency in 1996 and completed eighteen months before the River Eden was designated as a Special Area of Conservation. It has very limited use except as an Agency gauging station.
Such artificial barriers are a primary reason why freshwater ecosystems are the most threatened environment globally. It became clear almost immediately after the weir’s construction that adult salmon returning to the Eden to spawn were struggling to ascend it.
Just as importantly, shoals of juvenile salmon (smolts) migrating out of rivers to sea are delayed by weirs and become highly vulnerable to predation. Tagging studies on the nearby rivers Ettrick and Derwent have shown a loss of up to 40% of smolt runs – effectively 40% of the river’s whole salmon population – at similar major weirs.
In addition, investigations by Fish Legal on behalf of the Yorkshire Fly Fisher’s Club have found that the weir is likely to be illegal as it does not have an impoundment license.
Bob Bradney of Yorkshire Fly Fishers Club said: “For over 10 years our members have been asking the Environment Agency to do something about a weir that they own and which has been damaging a river we love. The inaction cannot continue. We and the river need them to do something, whether that is to modify or preferably, remove the weir entirely.”
Penelope Gane, Head of Practice at Fish Legal commented:
“Sometimes there is a reluctance to remove or modify weirs because they are part of the historic landscape or a flood defense. That isn’t the case here. Corby Weir is an illegal impoundment on a protected river that is threatening the survival of Atlantic salmon, a species that is in sharp decline in the Eden and other rivers in the UK.
She added: “The time for talking has passed. The Environment Agency now need to deal with this problem and give salmon on the River Eden a fighting chance.”
