Mojave River

A desert branch of the Serrano Native Americans called the Vanyume or Beñemé, as Father Garcés called them, lived beyond and along much of the length of the Mojave River, from east of Barstow to at least the Victorville region, and perhaps even farther upstream to the south, for up to 8,000 years in a series of villages, including the major village of Wá'peat. The Mohave's trail, later the European immigrants' Mojave Road, ran west from their villages on the Colorado River to Soda Lake, then paralleled the river from its mouth on the lake to the Cajon Pass. Native Americans used this trade route where water could easily be found en route to the coast. Garcés explored the length of the Mojave River in early 1776. Frémont named the river Mohahve after the Mohave people on April 23, 1844, although these people lived two mountain ranges away on the Colorado River. He had met six traveling Mohaves that day. Some early Mormon ranchers called it the Macaby River. Additionally another cutoff to the Old Spanish Trail had developed before 1844, where the trail forked northeastward from the Mojave River and Mohave Trail, east of what is now Yermo, California running over Alvord Mountain, to Bitter Spring, then through Red Pass, to join the Armijo route near Salt Spring in the Silurian Valley. From 1847, Mormons pioneered the wagon road that became the Mormon Road from Salt Lake City to Los Angeles, closely following the route of the Old Spanish Trail from Parowan, Utah. They followed the Mojave River from the Fork of the Road to the Lower Narrows and left the river for the Cajon Pass on the route Frémont had found. In 1849, Forty-niners late on the main trail to California used the Mormon Road as a winter alternative route to California, referring to it as the "Southern Route" of the California Trail. Later, emigrants to California followed the same route during the winter months. In 1855, the Mormon Road was improved, and the route changed in places, becoming a major commercial wagon route between Utah and southern California, ending Utah's winter isolation until the railroads arrived there in 1869. In 1859, as part of the Mohave War, the Mohave people's trail was improved as the wagon route of the Mojave Road. It followed the Mojave River from where the Mormon Road turned north away from the river at Fork of the Road, near Daggett, to where historic Camp Cady was located. It then followed the river to Soda Lake, where the road turned eastward to Fort Mojave, and in 1862 following the gold and silver strikes on the Colorado River, to Hardyville and the mining districts near it, and its connection at the head of the toll road to Prescott and the mines in the interior of Arizona Territory. From 1863 to 1864, the Mojave River valley was a refuge from the great drought in California in those years; cattle of some resourceful ranchers of southern California were preserved by its resources. ==Course==

The West Fork Mojave River flows into Silverwood Lake, formed by Cedar Springs Dam, which overflows in the Mojave River Forks Reserve area. On occasion, the lake releases water into the river. Downstream, Deep Creek meets the West Fork, forming the Mojave River mainstem immediately upstream of the Mojave Forks Dam, which provides flood control. Downstream of the dam, the Mojave River flows north and east, underground in most places, through Hesperia, Victorville, and Barstow. Near its terminus, the Mojave River flows out onto a large inland delta called the Mojave River Wash at the western edge of Mojave National Preserve. During heavy flows, the river reaches Soda Lake near Baker at the north end of Wash, and has reached Silver Lake, even further north, in historic times. For example, during the unusually wet winter of 2004–2005, the Mojave River flowed on the surface to Silver Lake and filled both Soda and Silver Lakes to a depth of several feet. A shallow pass, around 30 feet in height, separates Silver Lake from the Silurian Valley that contains Salt Creek, a tributary of the Amargosa River and thus the Death Valley drainage basin. The water in the river is mostly underground. The channel at the surface remains dry most of the time, but extreme flooding is possible. For example, during a heavy El Niño in the Mojave Desert, rains caused the Mojave River to overflow onto overpassing bridges on February 22, 1993, the most damaged being on Bear Valley Road, where Victorville and Apple Valley are separated. The water comes to the surface only in areas with impermeable rock, such as the upper and lower narrows near Victorville and in the Afton Canyon area northeast of Barstow. ==Afton Canyon Natural Area==

It is located northeast of Barstow along Interstate 15 between the Afton Road and Basin Road exits. Afton Canyon is designated as an Area of Critical Environmental Concern to protect plant and wildlife habitat, and to preserve scenic values of the Mojave River's riparian area within the canyon. The Rasor Off-Highway Vehicle Area boundary enforcement has begun to reverse the heavy off-road vehicles use and damage that occurred in the riverbed and canyon. Restoration projects are ongoing and have already brought the river's "proper functioning condition" from a "non-functioning" to a "functioning at risk" status. The objectives of the ambitious restoration project are to control exotic plants, particularly the phreatophyte Saltcedar - Tamarix (primarily Tamarix ramosissima and Tamarix parviflora), and restoring critical desert California native plant community "structural elements" for a functioning flora and fauna habitat. ==See also==
