Volunteer reported: HAB is extensive at 6413 Lower Lakewood and 3 properties around it. We patrolled our 3443 area and saw signs of HABs forming in the Van Riper Preserve and Poplar Beach both north of us. Some cottagers reported HABs forming around their docks that day. Some reported to CSI. But looked dissipated when we patrolled around 2 pm. HABs on Lower Lakewood have continued.
