Several water landmarks populate the Presidio. Mountain Lake near the corner of Lake Street and Park Presidio (where Highway 1 enters the tunnel on its way to the Golden Gate Bridge) was one of San Francisco's earliest sources of fresh water. In the past decade it has undergone extensive restoration. Lobos Creek, whose source is the surrounding watershed from Golden Gate Park to the ridges above Lobos Creek valley in the Presidio, remains one of only two original creeks still running on the surface in San Francisco (it ends at Baker Beach and the Pacific Ocean). Famously, El Polin Spring was an important water source for the original Spanish soldiers at the Presidio, and has also been recently restored and refurbished by the National Park Service. Excellent interpretive signage helps make historic sense of its surroundings after decades of neglect. The water courses from El Polin through MacArthur meadow and Tennessee Hollow to drain in the Crissy Field marsh, another interesting and successful restoration effort since the Park Service has taken over the Presidio.

Lobos Creek
Lobos Creek, seen here in 1958, which drains to Baker Beach, is one of only two creeks that still run above ground in San Francisco. It provides 4 million gallons a day of fresh water to the Presidio.
