The East Bay Regional Park District has closed Lake Temescal in Oakland for swimming due to a bloom of toxic blue-green algae. The rest of the park remains open.
The District plans to treat the algae with Pak 27, an oxidizing agent, next week. Last summer, Lake Temescal was closed for more than two months because of a toxic algae bloom.
Due to the drought and warm weather conditions, toxic algae blooms have been occurring more frequently in the Park District and elsewhere. District staff regularly monitor lakes and shorelines and post warnings or closures when appropriate. Toxic algae can be fatal to dogs, and we urge dog owners to be extra cautious with their pets near any bodies of water in the Park District.
The Park District encourages visitors who wish to enjoy water activities to visit these other popular lakes, beaches, and swim lagoons: Lake Anza at Tilden Regional Park in Berkeley, Cull Canyon in Castro Valley, Contra Loma Lagoon in Antioch, Don Castro in Hayward, Del Valle Recreation Area in Livermore, and Roberts Pool at Roberts Regional Recreation Area in Oakland.
The East Bay Regional Park District is a system of beautiful public parks and trails in Alameda and Contra Costa counties east of San Francisco Bay, established in 1934. The system comprises 119,000 acres in 65 parks including over 1,250 miles of trails for hiking, biking, horseback riding and nature learning.
