The San Jacinto River is a 68 km long river in Riverside County in the US state of California . It is part of the river system of the Santa Ana River . Its headwaters are in the San Bernardino National Forest , but the lower part of its approximately 2000 km² catchment area is in urban and cultivated land.
River course
The San Jacinto River arises at the western foot of the San Jacinto Mountains by the confluence of its precursors South Fork San Jacinto River and North Fork San Jacinto River; the site of the confluence is east of Valle Vista near California State Route 74 . Before its confluence, the South Fork San Jacinto River already flows through Lake Hemet , a 17,000,000 m³ reservoir that has been supplying the city of Hemet with water since 1895 . After the North and South Fork meet, the course of the actual San Jacinto River, which has now been created, continues northwest to Mystic Lake . Excess water flows away from here towards the southwest. At Perris, the San Jacinto River crosses Interstate 215 and flows further downstream into the artificial Canyon Lake in the city of the same name, Canyon Lake , which has a capacity of 14,700,000 m³. The San Jacinto River emerges from the reservoir again and flows into Lake Elsinore after another 4.8 km . Water only occasionally emerges from this natural lake; this emerging river is called Temescal Wash . At Corona the Temescal Wash flows into the Santa Ana River .
As an Endorheic Basin related to the Great Basin , the western portion of the San Jacinto Basin is part of the North American Continental Divide .
