A beach wheelchair is available free of charge on a first-come, first-served basis. See Park Accessibility on Quarry Lakes park page for more information.

Once the swim facility capacity is reached, there will be no new entries allowed for the remainder of the day. Please take this into consideration when you are planning your visit.

Swim Beach Water Quality Conditions

Quarry Lakes' Niles Beach is tested for bacterial levels weekly from April to October and twice a month from November to March. The map below indicates 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 Niles Beach. Our stop light sign is used to display the relative water quality from our latest bacteriological tests and blue-green algae conditions.

* Do not swim in the lake for 3 days after a rainstorm
