California and Water: How the Driest Rich Place on Earth Plumbed Itself
California grows a third of the nation's vegetables and waters forty million people on a brutal mismatch: about three-quarters of the water falls in the north, and about four-fifths of the demand sits in the south and the farm belt. This 8-part ReThink History series is the history of how the driest rich place on earth plumbed itself — and the bill now coming due. It traces the great grabs (Owens Valley and the Los Angeles Aqueduct, the drowning of Hetch Hetchy, hydraulic mining), the machine that followed (Reclamation, the 1922 Colorado River Compact, Hoover Dam, the Central Valley and State Water Projects, the fragile Delta), where the water actually goes (alfalfa, almonds, the Salinas 'upside-down river,' and the real Saudi-hay story), the over-drafted aquifers and the ghost of Tulare Lake that returned in 2023, the salmon and the Klamath dam removals and the tribal treaties California never honored, the shrinking Colorado and the 1944 treaty with Mexico, and the hard futures of desalination, data centers, and a whiplashing climate. The through-line: California is wedged between a set of rocks and hard places, and there is no clean solution — only trades, each with a loser. Told in part by a narrator who has lived through California's droughts and watched the ancient lake return and the Salinas Valley flood. Narrated by AI voices from sourced, human-reviewed research. © 2026 Selway Solutions LLC · <a href="https://history.selwaysolutions.io/index.html#license">Educational & Institutional Use License</a> · <a href="mailto:nick@selwaysolutions.io">Contact</a>

Episodes
Why California Can't Build Its Way Out of Its Water Crisis
Why not just desalinate the ocean, or engineer the shortage away? Because every exit is a trade with a loser.
The Colorado River's Fatal Math — and the Line to Mexico
The Colorado River ties California to six other states and another country — and it's running out.
Salmon, Stolen Water, and the Biggest Dam Removal in U.S. History
California's plumbing left out the living things — the salmon blocked behind the dams, the near-extinct Delta smelt caught in the pumps, and the Native nations whose water rights were never honored.
The Ground Is Sinking — and a Dead Lake Came Back
California overdrew its underground savings account for a century, and the ground itself is keeping the books: parts of the San Joaquin Valley have sunk nearly thirty feet, and in 2023 an ancient lake the maps said had been gone for 130 years suddenly came back.
Alfalfa, Almonds, and Why Saudi Cows Drink California Water
Agriculture uses about 80% of California's developed water, and the two biggest drinkers are alfalfa and almonds.
The 1922 Deal That Split a River That Didn't Have Enough Water
In 1922, seven states divided the Colorado River into more water than it actually carries — and California built the most engineered water system in human history on top of that math.
How Los Angeles Drained the Owens Valley — and Drowned Hetch Hetchy
Los Angeles reached two hundred miles into the Owens Valley and drained it; San Francisco drowned a valley inside Yosemite at Hetch Hetchy; and the Gold Rush's hydraulic miners buried the rivers until a judge finally said stop.
California's Water Paradox: Why the Rain Falls in the Wrong Place
California waters forty million people and the nation's biggest farm economy on a brutal mismatch: about three-quarters of its water falls in the north, and about four-fifths of the demand sits in the south and the farm belt.
