Stay out of the water at Olcott Beach, that's the message coming from the Niagara County Health Department.
Health officials say the water is not suitable for swimming because of, "unsatisfactory bacteriological water quality".
This advisory is expected to remain in effect until further notice.
In the meantime, health officials will continue to monitor the situation and say they will reopen the beach for swimming when conditions return to a safe level.
