Adobe Creek, historically San Antonio Creek, is a 14.2-mile-long (22.9 km) northward-flowing stream originating on Black Mountain in the Santa Cruz Mountains. It courses through the cities of Los Altos Hills, Los Altos, and Palo Alto on its way to the Palo Alto Flood Basin and thence to southwestern San Francisco Bay in Santa Clara County, California, United States. Historically, Adobe Creek was a perennial stream and hosted runs of steelhead trout entering from the Bay, but these salmonids are now blocked by numerous flood control structures, including a tidal gate at the creek's mouth and a long concretized rectangular channel culminating in an impassable drop structure at El Camino Real. The co-founders of Adobe Systems both lived on Adobe Creek.
