Current Water Quality Conditions and Available Test Results PDF

Crown beach is tested for bacterial levels weekly from April to October and twice a month from November to March. This map shows the sample sites which are: Crab Cove, the Bath House, Windsurf Corner, Sunset Road, 2001 Shoreline Drive, and Bird Sanctuary/Park Street. The East Bay Regional Park District works with the Alameda County Environmental Health Department in accordance with California Department of Public Health's Guidance for Salt Water Beaches to determine water quality at Crown Beach. Stop light signs along the beach are used to display the relative water quality from our latest bacteriological tests.
