The Mojave River: A source of water battles and innovation

Even in drought-stricken Southern California, the Mojave River could easily be described as one of the most unspectacular waterways in the Southwest. However, the historic significance of this strange desert paradox is hard to understate.

Through much of its 120-mile course, the Mojave River appears to be an irrelevant ribbon of sand. But in spite of its innocuous appearance, the river has provided the life blood for a broad stretch of the Mojave Desert since ancient times. It has also generated some of the West’s most ingenious water projects, and hard-fought legal battles.

The river flows above ground near its mountain sources, and through a few areas like the Mojave Narrows, and Afton Canyon, where the bedrock forces the water to the surface.

Indians were able to survive in the desert along the river where it flows above ground year-round, and provides an oasis of shade and food sources.

Early explorers and settlers counted on the river’s sections of dependable above-ground flow to get them across long, barren stretches of desert. The Mojave Road, The Mormon Trail, and The Old Spanish Trail, were the primary Indian and migrant trails into Southern California. These crucial routes all followed sections of the Mojave River through some of the driest stretches of the desert.

The Mojave River begins in the northern slopes of the San Bernardino Mountains, and flows northward under a dry bed of sand for much of its course. The east and west forks of the river merge just upstream of the present-day Mojave River Dam, in southeast Hesperia.

The eastern fork is known as Deep Creek, and its watershed begins in the mountains around and to the east of Lake Arrowhead. The watershed for the West Fork of the Mojave River begins in the mountains above, and to the west of Silverwood Lake. The river ends in Soda and Silver Dry Lakes, near the community of Baker.

One of the earliest settlers on the Mojave River was Captain Aaron Lane, a rancher who operated a trading post on the river. In 1858, Lane acquired a prime piece of Mojave River land near the present-day Turner Ranch, in Victorville and started a successful farm and cattle ranch.

Word of the successful agriculture effort on the Mojave River spread quickly, and sections of the river with regular flow, blossomed into a lush ribbon of farms and ranches.

A long-awaited railroad from San Bernardino, through the Cajon Pass, to Barstow was completed in 1885. Fred Perris of the California Southern Railroad chose a route through the High Desert that closely followed the grade of the Mojave River.

With a new railroad and a water source, land agents quickly began to promote the high desert as a prime region for new settlements. Beginning in the late 1800s, the High Desert communities of Hesperia, Apple Valley, Victorville, Oro Grande, Barstow, and Daggett, sprang up along the banks of the Mojave River.

In 1887, Judge Robert M. Widney and a group of investors incorporated the Hesperia Land and Water Company. The company purchased 35,000 acres on the high desert mesa that would later become the town of Hesperia. The company also began filing claims on water from the east fork of the Mojave River (Deep Creek), to irrigate the new colony.

The key to the success of the Hesperia Colony was an irrigation project to bring water from Deep Creek. Touted as a “marvel of engineering skill,” the project known as the “Hesperia Ditch” included a water channel blasted through solid rock, a ditch, and piping, that brought the water to a reservoir near the present-day Lime Street Park.

Challenges to Widney’s water rights began even before a spade was turned to dig the Hesperia Ditch. Land owners downstream in Victor and Oro Grande voiced loud opposition to the taking of their water, but Widney continued, and completed the canal in 1888.

A new high desert colony named Minneola was laid out in 1893, about 7 miles east of Daggett. A subsurface dam was built to divert the underground flow of the Mojave River into the “Mineola Ditch,” and an 11-mile irrigation channel was constructed to bring water to the townsite. The big dreams soon went bust, and in spite of the canal, the desert metropolis never materialized.

The largest single water project on the Mojave River was conceived in 1889, by Adolph Koebig, a San Bernardino city engineer. Koebig proposed a project to dam the upper portion of Deep Creek, and divert the Mojave River water south, into the San Bernardino Valley for irrigation.

The huge irrigation project to create the Little Bear Reservoir (later renamed Lake Arrowhead) began construction despite harsh objections and legal challenges from the downstream Mojave River water users. By the time the dam was finally completed in 1922, the Mojave River water users had successfully used the courts to block diversion of the water to San Bernardino.

The Little Bear Reservoir project was re-purposed from an irrigation project, to a recreational lake, and the precious Deep Creek water continues to flow into the Mojave River today.

By the early 1960s, population growth in the High Desert communities began to seriously overdraft the Mojave River Basin. Plans were made to bring State Water Project water into the Mojave River Basin, but delivery didn’t begin until 1991.

The State Water Project now supplies water from Northern California to recharge stations located along the Mojave River that stretch from Hesperia to Daggett. The recharge water percolates into the soil, where it is stored in the groundwater basins, and then pumped out for use by local water agencies.

Today, just as in the pioneer days, innovative irrigation projects continue to make the Mojave River the lifeblood of the high desert communities.
