It is sad news. Like most environmental problems its a complex issue, the catchment area for Bassenthwaite is large over 350km2. So they do need all the farmowners on their side to reduce over-grazing to stabilize the soil-erosion. Plus theres a 100km of river banks to plant up with woodland again to reduce soil erosion.
Its quite worrying the level of Phosphates in the lake and associated algal blooms. All the remediation measures to reduce the algal levels using barely straw and ultrasonic blasting seem to be unworkable for a lake this size. Even if they manage to reduce future pollution from my own involment in ocean sediments I know the effect that resuspension of material layed down over many years can have.
I'm glad to see Dr Winfields news that field trials are being conducted into a range of artificial spawning methods to keep (Vendance) eggs free from excessive silting.
