Another swim advisory has been posted for Gull Lake. The town government has said that samples collected on Monday by the Simcoe Muskoka Health Unit led to a recommendation for a swim advisory at Gull Lake Rotary Park Beach, due to high levels of e.coli. The town will be providing modified swimming lessons at Gull Lake Beach and be in contact with all participants should there be further changes to the schedule. During a swimming advisory, the beach is posted with warning signs that the most recent water samples showed bacteria in numbers that may increase the risk of developing minor skin, eye, ear, nose or throat infections or stomach illness. If anyone chooses to swim during a swimming advisory, they should avoid dunking their head or swallowing the water.
