  • Hesperia Ditch

    The Hesperia Ditch was the heart of a bold dream to turn part of the Mojave Desert into a thriving agricultural community. Built in the late 1880s, it was the centerpiece of an irrigation system designed to carry precious water from Deep Creek to the dusty, sun-baked mesa where Hesperia began taking shape.

    The story starts with a group of investors led by Dr. Joseph Widney, a former University of Southern California president. Along with the Hesperia Land and Water Company, Widney believed they could make the desert bloom by diverting water across rough terrain and under the Mojave River to what they hoped would become a green and prosperous settlement.

    In 1886, they began building the ditch. It wasn’t a simple trench—it was an engineering project that included miles of open canal, flumes, and a steel pipeline that dipped under the Mojave River. The water came from Deep Creek, a rocky stream that runs through a canyon just south of modern-day Hesperia. The company built a small concrete dam at the intake point to raise the water level and direct it into a ditch blasted and dug along the canyon wall. That channel clung to the hillsides, sometimes cut into solid rock, and sometimes supported by stone walls or wooden flumes. The route was carefully graded to use gravity to keep the water moving.

    One of the most impressive features of the system was a steel pipeline—about 14 inches in diameter—that crossed under the Mojave River in a kind of inverted siphon. From there, the water continued to a reservoir near present-day Lime Street Park in Hesperia. That earthen reservoir held about 58 acre-feet of water and was a local irrigation hub. Farmers could draw from it to water their fields, orchards, and gardens.

    At its height in the early 1890s, the ditch helped irrigate over a thousand acres of land. Apples, peaches, alfalfa, and other crops were planted, and the new town of Hesperia began to take root with a hotel, train station, and grand ambitions. Optimists thought it would become the next great inland farming colony.

    But dreams can be fragile in the desert. The irrigation system was expensive to build and even more complex to maintain. The 1880s land boom fizzled out, and Hesperia’s growth slowed. Legal disputes over water rights and the unpredictable nature of Deep Creek’s flow added to the difficulties. Floods often damaged the steel pipeline under the river and had to be repaired multiple times. By the early 20th century, much of the system was falling apart, and the amount of water it delivered had dropped significantly.

    In 1911, a new group took over under the name Appleton Land, Water and Power Company. They made some upgrades, including installing a larger 30-inch steel pipeline for part of the route and reinforcing the intake works. Still, only a few hundred acres remained in cultivation. In 1916, just 90 acres of orchard and 220 acres of alfalfa and corn were being irrigated—far less than what had once been envisioned.

    Even so, the ditch left its mark. Parts of the original channel along Deep Creek still exist today. A section of the Pacific Crest Trail follows the old ditch grade—its flat path a silent reminder of the engineers who carved it into the canyon wall over a century ago. The route is visible as a narrow shelf lined with old stonework along the hillside.

    At Lime Street Park, where the reservoir once stood, a historical plaque honors the day in 1886 when “life-giving water” first reached Hesperia. Without the ditch, the town might never have taken hold. Though modern wells and pumps eventually replaced the irrigation system, the ditch was the first to prove that water could be brought to the high desert—and with it, the chance for people to stay, build homes, and try to make the desert bloom.

    Today, the Hesperia Ditch is part of local lore, remembered as both a technical feat and a symbol of frontier determination. While the system didn’t fulfill all the lofty hopes of its founders, it made settlement possible in a place where nature had said no, and that’s no small thing.

  • Lake Adelaide

    by Walter Feller

    A small dam was erected to raise the water level up against a gate to a flume that could be opened letting water from Deep Creek flow into a stone-walled channel. This channel ran along a carefully continuous slope to a headwater, into a pipeline across the Mojave River, then on to an open reservoir in what is now the City of Hesperia, Ca.

    Canal at flume looking downstream.

    The slope along the canal has to be even to avoid turbulent flow. The walls need to be high enough all along the canal to maintain volume, accommodate hydraulic jump and prevent sloshing over the side. A smooth, even flow like that is called laminar flow.

    The smooth flow we look for in an open channel aqueduct is called ‘laminar flow.’ As water passes through the 3 or 4 miles, if the flow is turbulent, all kinds of contaminants may become entrapped and entrained in the water, which is undesirable.

    The floor of the channel needed to be flat and to hold a uniform, gentle, even slope for a long distance.

    So, water diverted at the flume passes through the gate and into a specifically engineered channel to be delivered to the next step, the headworks.

    This is the last stretch before the water leaves the mountains. The headworks were at the washed out area to the left.

    Think of the headworks as sort of a funnel with the water pouring from the channel into the top of the siphon. There most likely was a grate on there to keep large objects from falling into the pipeline and clogging it.

    The pipeline changes direction at Hesperia Lake. The origin of the lake is not exactly clear. One story I have heard is that the lake began when the pipeline was leaking and the water did not drain. There is a shallow well in the park that empties into the lake. The spiral-coiled pipe that was used may very well have sprung a leak under the high pressure of being the lowest point of the siphon, as well as a turning point in the line.

    The pipeline turned west at the lake and continued up the little canyon crawling up to the area locally known as ‘the mesa.’ The pipeline then terminated at an open reservoir at what is now Lime Street Park.

    All of this rather than dig a hole for a well.

    Rotary drilling was being developed, still. Water was down 500-600′ below the surface at this specific location where the reservoir needed to be. Building this canal the 12-14 miles it was, was preferable to digging a well that deep by hand.

    The location of the reservoir was well thought out. The water needed to be here for the community that was being developed. Also, water in an open reservoir that could be seen from a train window was a big attraction for those interested in the area.

    The canal and pipeline were completed in 1886 when the California Southern track was finished and trains began running.

    The water in the reservoir would be fed into the water system to fill the tank at the little railroad station across the street from where Walters’ General Store and the Hesperia Hotel would be built, and at the school just over on the east side of the tracks. There at the little schoolhouse at the center of the little community the water that would be delivered at a pressure of 45 PSI, which is about the perfect pressure for use in a home or commercial business.

    Water at this location was critical. 500 feet below the surface there was plenty of water, but the drilling technology to get to it was 30-40 years in the future.
    circa – 1900

    So, hopefully, all things have been considered and that is the story of how and why water was brought to our mesas and providing our opportunity to grow into the collective mega-empire we are to this very day. IMO.
