 The Task Force strictly enforced fishing restrictions around Lake Naivasha, arresting fishermen and confiscating and burning nets, in an attempt to stop overfishing and in particular catches of undersized fish.This was however controversial with locals who saw Lake Naivasha as a necessary and communal resource of food.On 13 January 2006, five days before her 70th birthday, Joan Root was murdered at her home in Lake Naivasha by four men who came to her door carrying AK-47s.
