Build-your-own model dams out of Mini Building Blocks. The Hoover set with 450 tiny pieces sits on top of the larger boxed Three Gorges set with 4,050 pieces. As the 2017 Chinese structure generates around eleven times the hydroelectricity of our esteemed 1936 dam, it seems appropriate their Mini Block sets are proportionally sized. The illustration on the box shows some complex structures on the right that do not appear in any photographs of the dam. We haven’t been able to learn why they were added to the model. Do you have any idea?
Artifacts that picture dams are many and varied. Ashtrays, plates, coffee cups, novelty salt and peppers, pennants, and medals decorated with the image of a specific river control project are created to sell as souvenirs. Among the scarcer of these gewgaws are diminutive models of these massive structures.

Tiny metal model of Bagnell Dam, which backs up the Osage River, creating Missouri’s Lake of the Ozarks. Little model dams can be considered “buildings” and they have fans, many of whom are architects. They have bid up the price of the models. A lot of dam memorabilia are unappreciated currently, but souvenir dams are still avidly sought by collectors.

Assembled, this Mini Block model of Hoover Dam is 6 ½ x 3 1/8 x 1 7/8 inches. Its box has a warning: “There is a choking hazard from the tiny pieces.” The box is also imprinted with “for ages 7 and up.” If your second grader can put this together, s/he should be starting MIT.
Recently, kits of Lego-like mini-blocks have been created that replicate dams. To our knowledge only three projects have been marketed: Hoover, Three Gorges, and Glen Canyon, which has sold out. Assembling these projects requires diligence and considerable dexterity working with very small objects. Though not a standard souvenir, the Hoover Dam model (below) is sold at a reasonable price on location at the National Park gift shop. They charge $17.99 plus tax. The Chinese kit for the larger Three Gorges Dam is available online for a bit over $100 plus shipping. Some offers are from China.
The two available kits (Hoover and Three Gorges) reflect the proportional size of their subjects. Like their real-life subjects, the Three Gorges box and model are larger than those of Hoover. If smaller than the Chinese dam, Hoover (Boulder) is still a celebrated American icon and symbol of our technological prowess.In the 89 years since it first clamped down on the unruly Colorado River, it has relinquished the title of “world’s biggest.” No longer can our press engage in such excessive hype as this Los Angeles Times quote of 1933:
“This great structure presents a picture of massive power, which overwhelms even the modern concept of the great Mayan builders.” Surpassing the Great Wall of China, the Acropolis, Hagia Sophia of Constantinople, and the pyramids of Egypt, the Times declared the dam to be “in fact, the greatest structure ever built by man.”
Dams serve symbolic as well as functional needs as evidenced by the numerous comparisons of Hoover Dam with the celebrated relics of fallen civilizations. In 1937, the Boulder Dam Service Bureau (whoever that was) published a booklet, Boulder Dam Book of Comparisons, price 25 cents. Among the absurd references between the giant hydroelectric project and past-built achievements were factoids like this: two great pyramids could be built from “material excavated to anchor the sides of Boulder Dam.” The gee-whiz aspect of giant construction projects is a fallback for dam publicists. The actual merits of a project are boring. Size matters.
That glorious Hoover has been eclipsed worldwide has not gone unnoticed. Online are numerous references to this fall. It now ranks Number 34 in height. Itaipu Dam between Brazil and Patagonia and Three Gorges on the Yangtze generate exponentially more electricity and Hoover’s reservoir storage capacity ranks Number 28. Even so it attracts millions of visitors and remains an object of wonder for some.
As the American Depression Era engineering miracle was endlessly lauded, China’s Three Gorges Dam is celebrated by its Communist government, but its preeminence may be brief. The People’s Republic has approved a dam in Tibet that will more than triple the electrical production of Three Gorges.
The golden era of unopposed big dams may be over but the tradition of treating massive water resource management structures with reverence is not. Size still seems to be in and of itself newsworthy. Dams are monuments comparable to other big construction projects like the great pyramids. The benefits they provide may be cited but rarely (until recently) have their negative features been covered by the media. The symbolism of dams has not only been neglected by the press, academic writers have, until recently, been blind to the popular mystique of these massive projects.
Even though these symbolic aspects of dams were not written about until recently, dams represented national pride. That began in earnest in the 1930s with the hyper-promotion of Hoover (Boulder) Dam. In Imaging Hoover Dam, Anthony F. Arrigo brilliantly makes this point and laments the cultural aspects of dams have traditionally been overlooked by scholars.

“Dam Jack” Savage (white guy in hat) and Chinese Delegation, on Yangtze River, 1944 (Public Domain photo)
Not only did America’s Bureau of Reclamation’s chief engineer design Hoover Dam, John L. (“Dam Jack”) Savage traveled the world promoting engineering solutions to wild rivers. In an historical irony, in 1944 one of his journeys was to China’s Yangtze River at the invitation of Chiang Kai-shek. Savage was enthusiastic about controlling that river.
He envisioned his “dream dam” there. Decades later, it came to fruition as Three Gorges – outpacing in size and power capacity our own Hoover Dam. He had sold the idea to the nationalists, but the replacement Marxist government actually built the multibillion dollar hydroelectric and flood control project. Dams have been power showcases of strong central governments of more than one political persuasion.
