# The Docket

> The Docket is a weekly publication about the decisions climate change is already putting in front of Americans: whether to buy the generator, whether the flood insurance is enough, whether to stay in the city you love. It follows the people making those choices now. It treats climate anxiety as a reasonable response to real conditions. It won't tell you what to do, but it shows the tradeoffs clearly.

## Issue 47 — Climate Past

Learning from history's climate interventions, migrations, and transformation attempts

### The Founding Negotiation

- [Dividing a Number at Bishop's Lodge](<https://anchor.is/docket/issue/47/archive/article/36624/markdown>) — By [Wren Castellano](<https://anchor.is/docket/team/73/markdown>) · Published 2026-08-28 · Format: The Founding Negotiation

In November 1922, commissioners from seven Western states spent eighteen days at a remote lodge outside Santa Fe dividing the Colorado River. They worked from roughly twenty years of streamflow records compiled by federal hydrologists, which was the best data anyone had. Half a century later, tree-ring scientists at the University of Arizona reconstructed the river's flows back to 1564 and found that those twenty years had caught the wettest stretch of comparable length in the entire record. The number the commissioners divided was real. It just wasn't the river's usual number, and nothing available to them in 1922 could have told them so.

### The Corrected Measurement

The trees that eventually exposed the Colorado River's overallocation don't grow anywhere near its banks. Ponderosa and pinyon pine on dry, rocky slopes record wet and dry years in their ring widths with a fidelity that twenty years of gauge readings at Lees Ferry never could.

### The First to See It

In 1976, two researchers at the University of Arizona published a 70-page bulletin that should have detonated the legal foundation of water management in the American West. Charles Stockton and Gordon Jacoby had used tree-ring data to reconstruct 400 years of Colorado River streamflow, and their conclusion was blunt: the river's long-term average flow at Lees Ferry was approximately 13.5 million acre-feet per year, roughly 10 percent less than the observed record and *far* below the 16.5 million acre-feet already committed to states and Mexico under the 1922 Colorado River Compact. The compact had been negotiated during the wettest quarter-century in at least four centuries. Every dam, every delivery contract, every city water system built since 1922 was premised on a river that was larger than it actually was.

### Consequence and Reckoning

- [The Century Built on the Wrong Number](<https://anchor.is/docket/issue/47/archive/article/36625/markdown>) — By [Wren Castellano](<https://anchor.is/docket/team/73/markdown>) · Published 2026-08-28 · Format: Consequence and Reckoning

The 1922 Colorado River Compact divided roughly 16.4 million acre-feet of water a year. The river's long-term average is closer to 14.5 million — a fact nobody could have known at the time. Then came Hoover Dam, Glen Canyon Dam, the Central Arizona Project, and cities that grew by millions. Each one made the original number more expensive to revise.

Lake Mead hit a provisional record low this week: 6.9 million acre-feet in a reservoir built to hold 30 million. The century of infrastructure described in our companion piece is now operating on a river that has averaged 12.4 million acre-feet a year since 2000, against the 16.4 million the compact divided. The largest mandatory cuts in the basin's history took effect in August. Three days later, Nevada sued.

The canals that drain South Florida's farmland and take pressure off the aging dike around Lake Okeechobee have to put the water somewhere. They put it in Stuart and Fort Myers, in tidal estuaries where people fish for a living and where the waterfront houses were bought on the assumption that the river would stay a river. In bad years the discharge carries cyanobacteria thick enough to close the water to contact. The drainage system is doing what it was built to do, and the cost falls on the estuaries.

In 1900, nine out of ten New Orleanians lived above sea level. By 1960, half the city occupied drained swampland that was already sinking underneath it. The pumps made that land buildable. Deed covenants, FHA appraisal rules, and segregated housing projects sorted out who could move onto it and when. When Katrina's water came, 76 percent of the people in flooded areas were Black. The drainage system did what it was built to do; everything around it decided who was standing on the results.

Yellow fever killed nearly eight thousand people in New Orleans in a single year. The city's answer, beginning in the 1890s, was to drain the back swamp that bred the mosquitoes and blocked its growth. The system worked — it opened territory, improved sanitation, helped end the epidemics. It also dewatered the peat under the city, and drained peat oxidizes into carbon dioxide and leaves. The ground comes down, and the lost elevation cannot be rebuilt. Roughly 60% of New Orleans now sits below sea level, kept dry by 120 pumps that can never stop.

After 1995, Chicago built a real emergency heat plan: cooling centers, free transport, 30,000 wellness checks in five days. Fewer people died when the heat came back. But one man turned down a free air conditioner because he was afraid of the electric bill. The plan could hand over the machine. It could not make running it affordable. The same diffuseness that beat the death certificate also marked where the response could reach and where it stopped.
