The River Ribble at the rear of the site runs very close beside The Nook, and the windows of room I've always had when I lodge there overlook it. Normally, it's a very pleasant little river. It empties into the Holme not far from there, so that river will be running black, as well.
One hopes there is nothing toxic in the dye that impacts on the river wildlife and vegetation thankfully all the employees managed to escape . One hopes the Business can recover it would be tragic if the Business went to the wall in such sad circumstances
