Lobos Creek (from the Spanish for sea lion, lobo marino — literally, "sea wolf") is a stream in the Presidio of San Francisco in San Francisco, California.

[2][3] Lobos Creek runs from runoff in the Presidio and Seacliff areas and underground seepage from springs that form Mountain Lake to the Pacific Ocean, marking the division between Baker Beach and China Beach.

[2][3] Conservation and restoration efforts are under way to remove invasive vegetation and improve water flow, in addition to deculverting.

The division, which is constantly changing due locals and kids digging, natural phenomenon.

About a million gallons per day—half the average flow of the creek—is diverted to a water treatment facility in the Presidio.
