Lambton Public Health says the water in Grand Bend is unsafe for swimming. Officials say it’s because of recent high levels of bacteria detected. The health unit conducts regular testing of the water. Swimmers should check Lambton Public Health’s website before going into the lake. Meanwhile, beaches in Kincardine, Goderich, Bayfield, and Port Stanley are safe and open for swimming. Pinery and Canatara Park beaches are open, but precautionary warnings are in place.
