High bacterial levels caused Bellevue to close the swim area at Newcastle Beach Park this afternoon, however the rest of the park remains open, according to a news release from the city.
The bacteria levels are probably from bird droppings caught in the currents of Lake Washington, the release says.
Water quality at beaches on Lake Washington is regularly tested by King County Water and Land Resources, and the tests will continue through the week, the release says.
King County Water and Land Resources, in cooperation with local jurisdictions, routinely tests and monitors water quality at beaches on Lake Washington. The county will continue to test and monitor the water next week.
