Lake Temescal

Prioritizing time outside can be difficult for those with busy schedules who live in urban areas. Lake Temescal rules out this excuse, offering itself as an accessible natural space, welcome to even the busiest of us all. 

Large amounts of blue-green algae, or cyanobacteria, have been recorded in multiple East Bay lakes, including Lake Anza in Tilden Regional Park and Lake Temescal in the Oakland Hills.

A toxic blue-green algae bloom has reared its head again in Lake Anza, forcing East Bay Regional Park District officials to close the popular summer destination just as swim season comes to an end.

Excessive heat and dry weather have fueled a toxic blue-green algae bloom in Lake Anza, leading to a temporary closure that began Thursday.
