Where is the drainage divide of San Francisco, separating areas of the city that drain to San Francisco Bay from those that drain directly to the Pacific Ocean?

The Wikipedia article on The Wiggle
, a biking route in San Francisco, mentions that "After climbing 50 more feet, the peak of The Wiggle is reached near Stanyan Street at the peninsular drainage divide, i.e., the dividing point between surface water flowing to the San Francisco Bay on the east side and flowing to the Pacific Ocean on the west."
Is there a map anywhere indicating this drainage divide? Alternatively, if no such map exists, how could I figure out where that divide is myself? (I guess this extends down the Peninsula as well, but I don't care about the Peninsula.)
