Colma Creek (Calif.)

Colma Creek is a small creek that flows to the San Francisco Bay from its source in the Crocker Hills portion of San Bruno Mountain State and County Park, north of San Mateo County's Guadalupe Canyon Parkway, with contribution from April Brook on San Bruno Mountain proper, south of the Parkway. It flows southwest and makes a 90-degree bend in Daly City to flow southeastward, through Daly City, Colma, and South San Francisco to the bay. Its small delta is between South San Francisco and the San Francisco International Airport. The creek has a tributary stream named Twelvemile Creek, which joins it from the southwest along Westborough Blvd. in South San Francisco.
