The San Jacinto River originates in the Santa Rosa and San Jacinto Mountains National Monument.
The Headwaters of the San Jacinto River
The river's headwaters are specifically located within the Santa Rosa and San Jacinto Mountains National Monument. This protected area serves as the starting point for the San Jacinto River's flow, collecting water that will eventually travel through a significant portion of Southern California.
Journey Through the San Jacinto River Watershed
From its mountainous origins, water from the San Jacinto River Watershed embarks on a journey downstream, playing a vital role in the regional ecosystem.
- The water eventually flows into Lake Elsinore, marking the river's terminal point and a significant destination for the watershed's runoff.
- During its natural flow, the San Jacinto River watershed is instrumental in the local ecosystem by carrying nutrient-rich sediment into the region's lakes each year. This natural process contributes to the nutrient cycling within these aquatic environments.
