Swim Beach Water Quality Program

NOTICE: Swimming at Shadow Cliffs is currently NOT ALLOWED due to low water levels.

Shadow Cliffs Beach is tested for bacterial levels weekly from April to October and twice a month from November to March. The map below shows the two sample sites on the beach. 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 Fresh Water Beaches to determine water quality at Shadow Cliffs Beach. Our stop light sign is used to display the relative water quality from our latest bacteriological tests and cyanobacteria (blue-green algae) conditions.
