San Juan Creek is a stream in Orange County, California that consists of a catchment basin encompassing 133.9 square miles[2][3]. Its mainstem rises in the Santa Ana Mountains, in the Trabuco Ranger District of the Cleveland National Forest. From here, it parallels Ortega Highway as it winds west and south through San Juan Canyon, where it is joined by numerous small tributaries, and is joined by the Arroyo Trabuco and Oso Creek as it passes through San Juan Capistrano.

Once out of the foothills, San Juan Creek flows thorough the city of San Juan Capistrano where groundwater flow direction generally is from the northeast to the southwest. Groundwater in this basin at the San Juan Capistrano reach is considered good[4]. Recent efforts of stream conservation have been in the planning stage including habitat conservation plan work[5].
