Efforts fail to remove algae bloom from Lake Temescal in Oakland

OAKLAND, Calif. (KGO) -- Efforts to remove toxins from Lake Temescal are apparently not working.

The lake is now expected to remain closed this weekend.

SKY7 HD showed people on the beach Wednesday avoiding the water.

The popular swimming area in the Oakland Hills has been closed since last week when toxic blue-green algae was discovered.

Water management supervisors said they treated the water with an oxidizing agent, but new tests shows toxins remain in the lake.

An algae bloom closed the popular lake for two months last year.
