Major Tributaries
Among the many streams flowing from the range, Piru Creek and Sespe Creek stand out as the largest tributaries of the Santa Clara River. These waterways are essential for transporting mountain runoff to the valley floor.
Reservoirs
Within the boundaries of the mountains, Lake Piru serves as the only major reservoir, providing a critical point for water storage and management in the region.
