The County still has an advisory up for Dog Beach in OB. They advise that bacteria levels exceed health standards and that people and dogs should avoid water contact in the advisory area. It’s been on since June 6. The advisory covers the San Diego River outlet to 300 yards south.
There’s also an advisory for a part of Mission Bay — for the North Cove of Vacation Isle and 150’ each side of the southern drain. This has been on since May 30, 2024.
The County advisories are issued to warn beach users as follows:
– A Bacterial Exceedance Advisory is issued when ocean or bay water sample results exceed State health standards due to high bacteria levels.
– A Precautionary Advisory is issued when DEHQ determines there is a potential for elevated bacteria due to dredging, lagoon opening or other sources in the
vicinity of coastal areas.
The County Department of Environmental Health and Quality directs beach users to avoid contact with ocean and bay waters in the advisory area.
Beach water quality monitoring uses bacterial indicators to test for the presence of possible pathogens. The bacterial indicators are not specific to humans, and may be from other sources including wildlife, pets, soils, and rotting vegetation like kelp. Ocean or bay waters with elevated bacterial indicators may contain human pathogens that can cause illnesses.
Tuesday, June 11: the advisory is still in effect at Dog Beach.
