WILSON – The state Parks Department announced Friday that poor results in water samples have prompted the closure of Wilson-Tuscarora State Park to swimming.

The beach on Lake Ontario will be closed until at least Sunday, spokeswoman Angela Berti said.

It was the first closure this year at Wilson-Tuscarora, which is several miles west of Krull Park Beach in Olcott, which has been closed three times this season because of elevated levels of e. coli bacteria.
