Megawatts by Microwave

In 1914, the Bureau of Reclamation, acting under the Department of the Interior, began exploring the potential of the Columbia River. The goals were ambitious:

• Transform arid landscapes into a "Northwest Imperial Valley" via irrigation.
• Extract valuable minerals from mountain ores using industrial electricity.

By 1916, Oregon's State engineer proposed the Bonneville site as a matter of national security. He envisioned a facility that could produce fertilizer during peacetime and critical nitrates during wartime. Additionally, the project promised to:

1. Submerge the Cascade Rapids.
2. Push slack-water navigation roughly 40 miles east toward The Dalles.

The Rivers and Harbors Act of 1925 further formalized this by tasking the Secretary of War—via the U.S. Army Corps of Engineers—to estimate the costs of surveying all navigable streams where power generation seemed viable.

The Paradox of the Army's Involvement

"It is difficult to succinctly explain why, exactly, the United States Army has spent much of its history involved in the construction of dams."

This phenomenon is a cocktail of historical accidents, federal bureaucratic infighting, and deep-seated American cultural values. In the text Cadillac Desert, Marc Reisner argues that water control in the West was less about utility and more like a religious crusade "religious project," driven by a belief that conquering the rivers was a manifest destiny.

While the Bureau of Reclamation was specifically created for this "destiny," the Army had already spent a century improving rivers. This created a professional friction:

The New Deal and the Columbia River

The Columbia River Project was driven by several factors: the need to mitigate flooding, the desire for irrigation, and—eventually—the economic desperation of the Great Depression.

Franklin D. Roosevelt, influenced by the Niagara Falls plants during his time as Governor of New York, integrated hydropower into his New Deal. By 1934, a Regional Planning Commission mapped out several dams, most notably the Grand Coulee and the Bonneville.

Unlike previous projects, the energy produced here would exceed the needs of simple irrigation pumping. To manage this, the government sought a distribution model similar to the Tennessee Valley Authority (TVA).

Technical Capacity

The Bonneville Dam focuses primarily on power generation rather than water storage. Its capacity can be expressed as: $\text{Bonneville Capacity} \approx 1.2 \text{ GW}$ In contrast, the Grand Coulee eventually reached a massive scale: $\text{Grand Coulee Capacity} \approx 7 \text{ GW}$

The Battle for Power Control

The surge in electricity sparked a political war over ownership:

• Public Camp: Argued for government marketing and equitable distribution.
• Private Camp: Argued that power should be contracted to private firms (e.g., Portland General Electric).

The New Deal era ensured the public camp's victory. While the region didn't get a full TVA, Congress created the Bonneville Power Administration (BPA).

The BPA (now under the Department of Energy) implemented the postage stamp rate. This meant that whether you were a massive city utility or a tiny rural cooperative, the price per kilowatt was the same.

Industrial Transformation

This abundance of cheap, reliable power triggered a regional industrial explosion. The Columbia Gorge became the heart of the U.S. aluminum industry, producing roughly $\frac{1}{3}$ of the nation's supply until the 1970s. This infrastructure also paved the way for aerospace giants, most notably Boeing.

The legacy of the BPA persists today, profoundly shaping the economies of towns like Boardman, Umatilla, and The Dalles.
