Lake Mathews is a large reservoir in Riverside County, California, located in the Cajalco Canyon in the foothills of the Temescal Mountains. It is the western terminus for the Colorado River Aqueduct that provides much of the water used by the cities and water districts of the Metropolitan Water District of Southern California. The reservoir is fenced and closed to all public access. The lake is near the Riverside community of Lake Hills, and is skirted by Cajalco Road on the south, El Sobrante Road on the north and east, and La Sierra Avenue on the west. La Sierra Avenue traverses the top of the west dike.
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.
The Temecula Valley is a graben rift valley in western Riverside County, California.
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.
Rancho Temescal was a farming outpost of Mission San Luis Rey de Francia, one of the 21 Franciscan missions established in California by Spain during the late 18th and early 19th centuries. The Mission was located on the coast where Oceanside, California is today.

Morrell Canyon Creek is a stream or Arroyo, tributary to San Juan Creek, located in the Cleveland National Forest in Riverside County, California, at an elevation of 3,080 ft (939 m), in the Elsinore Mountains northeast of Elsinore Peak. It arises on the eastern slope of San Mateo Peak. An eastern fork draining the Morrell Potrero joins it a little over a mile north of its source and then flows northwestward about a third of a mile where it turns southeast descending the narrow Morrell Canyon east of Lion Spring. After descending 2.5 miles it turns north for half a mile then returns to a southwestern direction for another mile, the canyon widening here until it turns northwestward and down a steep canyon again for half a mile where it takes in from the right Decker Canyon Creek and Long Canyon Creek. It then turns southwestward again into a wider canyon and descends to its confluence with Bear Canyon Creek and becomes the head of San Juan Creek.
Los Alamos Canyon Creek, a stream or arroyo, tributary to San Mateo Creek, in the Cleveland National Forest in Riverside County, California. Its source is at an altitude of 2300 feet, in a canyon on the south face of the ridge of Elsinore Mountains that descends to the southeast from Elsinore Peak. The creek descends southward for a short distance then turns southwest for 4 miles where it turns west for 3 miles down Los Alamos Canyon to its confluence with San Mateo Creek at an elevation of 1312 feet.
Temescal Mountains, also known as the Sierra Temescal, are one of the northernmost mountain ranges of the Peninsular Ranges in western Riverside County, in Southern California in the United States. They extend for approximately 25 mi (40 km) southeast of the Santa Ana River east of the Elsinore Fault Zone to the Temecula Basin and form the western edge of the Perris Block.
Temescal Valley in California is a graben rift valley in western Riverside County, California, a part of the Elsinore Trough. The Elsinore Trough is a graben between the Santa Ana Mountain Block to the southwest and the Perris Block on the northeast. It is a complex graben, divided lengthwise into several smaller sections by transverse faults. The Temescal Valley is one of these graben, at the northern end of the trough. The Temescal Valley graben is bounded northeast side by the Lee Lake longitudinal fault and similarly on the southeast by the Glen Ivy Fault.
The Perris Block is the central block of three major fault-bounded blocks of the northern part of the Peninsular Ranges. The Perris Block lies between the Santa Ana Block to the west and the San Jacinto Block to the east. The Perris Block, was named by Walter A. English in 1925 for the city of Perris, located near the center of the block.
Rice Canyon Creek is a tributary creek or arroyo of Temescal Creek in Riverside County, California. Rice Canyon Creek has its source at the head of Rice Canyon at an elevation of 3440 feet in the Santa Ana Mountains at 33°41′54″N117°24′11″W east of the 4313 foot peak on the north south divide of the range. It is a wash that runs down from the canyon mouth 33°41′07″N117°27′08″W at 1631 feet to its mouth at its confluence with Temescal Creek near Alberhill, California at an elevation of 1220 feet. Rice Canyon Creek has a tributary, Bishop Canyon Creek which enters the wash on the left a little below the mouth of Rice Canyon at 33°42′05″N117°24′07″W.
Warm Springs Valley is a valley located within the city of Lake Elsinore in Riverside County, California. It lies between the main body of the Temescal Mountains to the north, east and south and the Clevelin Hills to the west. The valley was named for the warm springs that used to be found flowing there.
Gavilan Hills, sometimes called the Gavilan Mountains, are a range of the Temescal Mountains, in Riverside County, California. The name given them came from local New Mexican and Californio miners of the mountains and Gavilan Plateau. In Spanish Gavilan, means "sparrow hawk".

Temescal Creek flows northward through the canyon from where it heads at 33°42′33″N117°21′43″W in Warm Springs Valley into the upper reach of the Temescal Valley near Alberhill, California. Coming from the Temescal Mountains to the east, Gavilan Wash has its confluence with Walker Canyon near mid way along its length, and Alberhill Canyon has its confluence with Walker Canyon at its mouth.
Eagle Valley is a basin in the Temescal Mountains, of Riverside County, California. It has a elevation of 1,283 feet / 391 meters. The basin is overlooked by summits of the Temescal Mountains on the west, north and east, the tallest is 1,857 foot Arlington Mountain on the northeast.
