Lakeshore town officials announced Monday evening that a boil water advisory in place since Dec. 23 for more than 550 properties had ended. Properties in northeast Lakeshore, including Lighthouse Cove, Crystal Beach, Laforet Beach and Couture Beach, were told to boil their water after a water main break Friday morning. “We appreciate everyone’s patience,” said Krystal Kalbol, Lakeshore’s corporate leader of operations. “We’d also like to thank all of our dedicated staff who responded.”
