Due to the drought and unusually warm weather conditions, toxic blooms of blue-green algae and other water-quality issues are occurring more frequently in the East Bay Regional Park District and elsewhere. We monitor our lakes and shorelines regularly, and post warnings and closures when appropriate. Here’s a current update of which lakes and shorelines are affected:
The Park District encourages visitors who wish to enjoy water activities to visit these other popular lakes, beaches, lagoons and pools: Cull Canyon in Castro Valley, Contra Loma Lagoon in Antioch, Don Castro in Hayward, and Roberts Pool at Roberts Regional Recreation Area in Oakland.
