Del Puerto Creek, originally Arroyo de La Puerta (Creek of the Door) is a tributary of the San Joaquin River draining eastern slopes of part of the Diablo Range within the Central Valley of California, USA. The Creek enters the San Joaquin River, about 2 1/2 miles southeast of Grayson, California in Stanislaus County.[1][2]
Arroyo de La Puerta was a watering place on El Camino Viejo named for the narrow exit (Puerta or Door) where the creek emerged from the La Puerta Canyon into the San Joaquin Valley. It provided the southern boundry of Rancho Pescadero (Grimes) and the northern boundry of Rancho Del Puerto.[3]
