The San Jacinto River is a 42-mile-long (68 km) river in Riverside County, California. The river's headwaters are in Santa Rosa and San Jacinto Mountains National Monument. The lower portion of the 765-square-mile (1,980 km2) watershed is urban and agricultural land. As a partially endorheic watershed that is contiguous with other Great Basin watersheds, the western side of the San Jacinto Basin is a portion of the Great Basin Divide.
Rancho La Laguna was a 13,339-acre (53.98 km2) Mexican land grant in present-day Riverside County, California given in 1844 by Governor Manuel Micheltorena to Julian Manriquez. The rancho lands are included in the present day city of Lake Elsinore and Wildomar. At the time of the US Patent, Rancho Laguna was a part of San Diego County. The County of Riverside was created by the California Legislature in 1893 by taking land from both San Bernardino and San Diego Counties.
Temescal Creek is an approximately 29-mile-long (47 km) watercourse in Riverside County, in the U.S. state of California. Flowing primarily in a northwestern direction, it connects Lake Elsinore with the Santa Ana River. It drains the eastern slopes of the Santa Ana Mountains on its left and on its right the western slopes of the Temescal Mountains along its length. With a drainage basin of about 1,000 square miles (2,600 km2), it is the largest tributary of the Santa Ana River, hydrologically connecting the 720-square-mile (1,900 km2) San Jacinto River and Lake Elsinore watersheds to the rest of the Santa Ana watershed. However, flowing through an arid rain shadow zone of the Santa Ana Mountains, and with diversion of ground water for human use, the creek today is ephemeral for most of its length, except for runoff from housing developments and agricultural return flows.
