    Toxic Algae Prompts Swimming Bans at Two More East Bay Lakes
    NBC Bay Area
    Toxic algae has caused two more swimming bans at East Bay lakes.

    Outbreaks of toxic algae have prompted swimming bans at Lake Temescal in Oakland and Quarry Lakes in Fremont, according to the East Bay Regional Park District.

    The lakes remain open for fishing, and the parks remain open for picnicking, hiking and other activities, the district said.

    The closures bring to three the number of swimming bans at lakes in the district due to toxic algae. Lake Anza at Tilden Regional Park in Berkeley has been closed since August. Visitors at Lake Del Valle in Livermore and Shadow Cliffs in Pleasanton are warned to swim at their own risk.

    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.

    Other lakes in the district that contain algae include Big Break Regional Shoreline, Lake Chabot and Shinn Pond, according to the park district website. District staff monitor all lakes regularly. For updates, visit the park district website.
