Lake Temescal and Quarry Lakes Closed to Swimming Due to Toxic Algae

10/4/2016

The East Bay Regional Park District has closed Lake Temescal and Quarry Lakes to swimming due to outbreaks of toxic algae.

The lakes remain open for fishing and the parks remain open for picnicking, hiking and other activities. Lake Temescal is located at Temescal Regional Recreation Area in Oakland and Quarry Lakes Regional Recreation Area is in Fremont.

Lake Anza at Tilden Regional Park in Berkeley has been closed since August due to a toxic algae bloom. The Park District’s swim season is over, but visitors may swim at their own risk at Lake Del Valle in Livermore and Shadow Cliffs in Pleasanton.

Exposure to toxic algae, either through ingestion or skin contact, can cause rashes, skin and eye irritation, allergic reactions or gastrointestinal problems, according to the California Department of Public Health. Toxic algae can be fatal to dogs and they should refrain from direct contact.

Park District staff monitor all our lakes regularly. Updates and more information.
