Urban runoff may contain large amounts of bacteria from a variety of sources such as animal waste, soil, and decomposing vegetation. While many coastal storm drains within San Diego County are permanently posted with white metal warning signs, additional temporary warning signs are not posted for general advisories.
Activities such as swimming, surfing and diving should be avoided in all coastal waters for 72 hours following rain. This includes all coastal beaches and all of Mission Bay and San Diego Bay. Elevated bacteria levels can persist after a rainstorm depending upon the intensity of the storm, volume of runoff and ocean and current conditions.
Tijuana Slough National Wildlife Refuge and Border Field State Park
The Department of Environmental Health has issued a water contact closure for the ocean shorelines at Border Field State Park and the Tijuana Slough National Wildlife Refuge due to sewage-contaminated flows from the Tijuana River entering the United States.
The closure area includes the beach-line from the International Border to the north end of the Tijuana Slough National Wildlife Refuge (south end of Seacoast Drive). Signs will remain in place until sample results indicate the ocean water is safe for recreational use.
