Anne Arundel County health authorities warned the public Wednesday to stay out of the water at four beaches or recreational areas because of high bacteria levels. People are urged not to swim, ski or have direct contact with the water at Herald Harbor in Crownsville, at Lake Claire in Cape St. Claire, at Magothy Manor in Arnold and at Glen Isle in Riva.

Regular testing of the county's recreational waters detected high bacteria levels in samples taken on Monday. Glen Isle has had a swim warning since June 13, though, based on earlier tests.
