GRAVENHURST — Just as beaches begin to re-open, the first of the annual summer swim advisories at Gull Lake Rotary Park has been announced today.

In what has become an all-to-common occurrence at the downtown watering hole, swimmers are again faced with signs warning them to use the water at their own risk.

The Town of Gravenhurst posted the advisory signs Tuesday, June 23.

They say, in a release today, that based on beach water samples collected by the Simcoe Muskoka District Health Unit (SMDHU) on Monday June 22, it has been recommended by the SMDHU that Gull Lake Rotary Park Beach be posted with swim advisory signs.

The beach itself will remain open to the public.

Officials say that during a swim advisory the beach is posted with warning signs that the most recent water samples showed bacteria in numbers that “may increase your risk” of developing minor skin, eye, ear, nose or throat infections, or stomach illness.

They say that if you choose to swim during a swim advisory, avoid submerging your head or swallowing the water.
