How Workers Built the 233-Mile Los Angeles Aqueduct Across the Mojave Desert

In 1908, William Mulholland sent 3,900 men into the Mojave Desert to build a 233-mile gravity-fed aqueduct by hand — no pumps, no heavy machinery, and a budget he hit to the exact dollar. Most of the men who built it are not in the history books. Some are not even in the official death count. This video tells the full construction story of the Los Angeles Aqueduct — how a self-educated Irish immigrant engineered one of the most precise water delivery systems in American history, how 142 tunnels were drilled by hand through solid granite, how inverted siphons carried water 895 feet into desert canyons and back up the other side using nothing but physics, and how the workforce that made it possible scattered the day after completion and left almost no record of where they went. The aqueduct has been running continuously since November 5, 1913. The concrete poured in the Mojave Desert in 1910 is still in service. Jose Reyes, listed in the payroll ledger as "Mexican laborer, Grade C," drilled rock in 110-degree heat for seven months in 1910. After October of that year, his name does not appear in any record we have found. If you care about the men who built this country with their hands — the workers nobody ever wrote a book about — subscribe to Forgotten Labor and hit the bell. Every video in this series recovers a story that official history left out.
