Temecula Creek, formerly known as the Temecula River,^[2] runs 32.6 miles (52.5 km)^[3] through southern Riverside County, California, United States, past the rural communities of Radec and Aguanga, and ending 0.5 miles (0.80 km) southeast of the original city center of Temecula. The creek is filled with boulders and is typically dry and sandy. It is a relatively undeveloped coastal-draining watershed.^[4] Until the 1920s, water flowed in Temecula Creek year-round.^[5]

History[]

A Luiseño Indian rancheria named Temeca or Temeko was named as early as 1785. In 1828 Temecula became the name of a rancho of Mission San Luis Rey. Alfred Kroeber noted that the name may be derived from the Luiseño word temet meaning "sun".^[6] The village of Temecula originated on a bluff on the south bank of Temecula Creek opposite the old Wolf's Store according to an 1853 survey.^[7]

In 1948, the owners of the Vail Ranch built a 132-foot-high (40 m) dam on Temecula Creek, the Vail Lake Dam, approximately 10 miles (16 km) above the confluence with the Santa Margarita River. Today the lake is a public recreational use area.

Watershed[]

Temecula Creek originates on the north slope of Aguanga Mountain, flows northeast 1 mile (1.6 km) to , where it continues northwest through Dodge Valley, , , , , Butterfield Valley, into Vail Lake Reservoir, after which it flows southwest through Pauba Valley to Temecula Valley where it joins Murrieta Creek.^[1] Temecula Creek has a slightly larger drainage area than Murrieta Creek. The Santa Margarita River begins at the confluence of the two creeks at the head of .^[8]

With the encroachment of homes on both sides of Temecula Creek, portions may be channelized.^{[citation needed]}

Ecology[]

Biologically diverse, supporting both coastal and desert fauna and flora, it is bounded by the Agua Tibia Wilderness area and the Cleveland National Forest. The creek supports coastal sage scrub, including Jojoba, alluvial fan scrub, mesquite bosque mix, coast live oak woodland, and mature Fremont cottonwood-willow woodland.^[9]

In addition to riparian breeders, birds include least Bell's vireo, Nuttall's quail, ladder-backed woodpecker, and California and Gambel's quail. Arroyo southwestern toad are also found in Temecula Creek.^[9]

North American beaver (Castor canadensis) may gradually raise the water table and return portions of the stream to perennial flow at sitei such as its confluence with Murrieta Creek.^[10] However, cattle grazing along Temecula Creek have injured its understory.^[9]
