Minutes before sunrise Monday, nearly a dozen boat owners were already lining up in the Beals Point parking area for the first day of boat inspections and a 30-day quarantine aimed at preventing an invasive species from finding its way into Folsom Lake. “It’s long before the scheduled 9:30 a.m. start time for inspections, but I’m glad I got here early,” said Rudy Divin, a fishing guide. Starting Monday, Folsom Lake and Lake Clementine are closed to all motorized and trailered vessels for the next month. All boats seeking to launch on either lake are required to go through a mandatory 30-day quarantine.
