The San Gorgonio River is a 26.8-mile-long (43.1 km)[1] river primarily flowing in western Riverside County, with a small upstream section in southwestern San Bernardino County, in southern California.
Geography
The river's headwaters are in the San Bernardino Mountains, southwest of San Gorgonio Mountain at the southern base of Galena Peak within Sand to Snow National Monument.
The river flows southwest through Banning Canyon then cuts back southeast through the town of Banning, California. It then heads east to its confluence with the Whitewater River in the western Coachella Valley. It drains the land east of the San Gorgonio Pass, while the South Fork of the Santa Ana River drains the land west.
The river is intermittent, with significant flow only following winter storms and snowmelt in the spring.
