I would like to thank all the contributors, contracters, bailiffs, fishermen and birders who have contributed to this report in these difficult times, especially when the general public were overrunning the lake causing a degree of mayhem and destruction. The poachers were better mannered! In particular, the fishing bailiffs of the Colne and Stocker’s who were on the front line, however there was a disappointing response from the conservationists. We are all in this together so thank you all.
