The Legacy of John Wesley Powell: Why the West Still Fights Over Water

If you want to understand the American West — its growth, its conflicts, and its future — you have to start with water. And no one explained this better than John Wesley Powell, the one‑armed Civil War veteran who became the first person to navigate the full length of the Colorado River.

In the video below (the source of this post), Stanford historian David Kennedy revisits Powell’s warnings and shows how astonishingly relevant they remain today.

🌵 Powell’s Big Insight: The West Is Arid

In 1879, Powell published a landmark report: “The Lands of the Arid Region of the United States.” His message was simple but revolutionary:

The American West does not have enough water for traditional settlement.

He argued that state borders should follow watersheds, not straight lines. If you’ve ever looked at a map of the “square states,” you know exactly how thoroughly his advice was ignored.

🏗️ Nation‑Building Through Dams

After the 1902 Reclamation Act, the federal government reshaped the West with massive dam projects:

• Hoover Dam
• Glen Canyon Dam
• Dozens more across the Colorado, the Salt River, and beyond

These dams made the modern West possible — its cities, farms, and booming post‑WWII population. But they also created a system stretched far beyond what Powell ever imagined.

🐟 New Pressures, New Realities

Kennedy highlights several forces now pushing the system to its limits:

• Population growth far beyond original water‑system designs
• Environmental protections, like the Delta smelt ruling that shut down major pumps
• Groundwater overuse, causing land to sink dramatically
• Climate change, reducing snowpack and accelerating runoff

The result? Reservoirs like Lake Mead have dropped to historic lows, exposing a “bathtub ring” now dozens of feet tall — a stark reminder that the old water regime is breaking down.

🔥 A Region at a Crossroads

The West’s prosperity, politics, and identity have all been shaped by water. As Kennedy notes, even presidential inaugurations shifted westward — literally — when Ronald Reagan insisted on facing the western horizon in 1981.

But today, the region faces a new era defined by scarcity, conflict, and adaptation.
