A group that has focused on keeping Lake Lanier full and clean in the past is putting more emphasis on safety advocacy. The Lake Lanier Association, in a press release this week, said it will join with government and marine-based organizations around Lanier to promote general water safety through education, with efforts aimed at improving awareness and possible lobbying efforts for state legislation. The efforts come in the aftermath of two highly publicized boating accidents on Lanier, one that killed two Buford boys, Griffin and Jake Prince, and one that critically injured a boy reported to be the stepson of entertainer Usher.
