The first weed treatment this summer on Lake Zoar seemed to be effective, but there was a regrowth. The post treatment survey was delayed however due to short staffing with the research agency. A second weed treatment will be scheduled for this month for the targeted areas with regrowth. It's estimated at one quarter of the total acres originally treated. The Lake Zoar Authority says improved signage has been requested to alert residents of the second treatment. The Cyanobacteria Monitoring Program at Western Connecticut State University continues this month, with results continuously low. Measurements for blue green algae are taken at Eichler’s Cove in Newtown, Jackson’s Cove in Oxford and Kettletown State Park in Southbury.
