Seguin Township has “posted” Horseshoe Lake beach due to a potential blue-green algae bloom. Councillor Dale Graves posted the warning to Facebook advising that drinking, swimming or any other contact with the water at Horseshoe Lake Beach was not recommended. Water samples have been sent out for testing and the results are expected back some time on Tuesday. At this time the beach has warnings posted and it is believed that just the beach area is affected.
