In the 1970s, the Soviet Union pursued one of the most extreme engineering proposals in modern history: a plan to detonate 250 nuclear bombs to excavate a canal across northern Russia.
The goal was to reverse the natural flow of rivers and divert water southward to replenish the shrinking Caspian Sea. At the center of this effort stood the Pechora–Kama Canal project—an ambitious and ultimately abandoned idea that formed part of the USSR’s broader “Northern river reversal” scheme.
To test the feasibility of using nuclear explosions for large-scale excavation, Soviet scientists carried out a real-world experiment in 1971. Known as the Taiga nuclear test (A Niche in the Library of Babel, SciSpace, Wikipedia), it involved the simultaneous detonation of three underground nuclear devices near the village of Vasyukovo in Perm Oblast.
The test created a massive crater—but also raised serious concerns about the environmental fallout, geological stability, and human health risks associated with scaling the concept to 250 nuclear blasts. Though the full plan was never realized, the Taiga test remains a haunting symbol of Cold War-era ambition—and recklessness.

1961: The canal project gains renewed interest as part of the Soviet Union’s grand “Northern river reversal” scheme, which includes diverting Siberian rivers southward.(Wikipedia)
1965: The Soviet government considers using nuclear explosions for large-scale civil engineering projects under the “Nuclear Explosions for the National Economy” program.(SciSpace)
1969: Gosplan, the Soviet State Planning Committee, approves further exploration of using nuclear detonations for canal excavation.
February 23, 1971: The “Taiga” nuclear test is conducted near the village of Vasyukovo in Perm Oblast. Three underground nuclear devices, each with a yield of 15 kilotons, are detonated simultaneously to simulate canal excavation. (Wikipedia, sonicbomb.com)
Late 1970s–1980s: Growing environmental concerns and opposition from scientists and government officials lead to the project’s decline.
1986: The Soviet government officially abandons the Northern river reversal plan, including the Pechora–Kama Canal project. (Wikipedia)
The Taiga Nuclear Test
The Taiga test aimed to assess the feasibility of using nuclear explosions for canal construction in challenging geological conditions. The test site featured saturated alluvial deposits, which posed significant slope stability issues. (Wikipedia, sonicbomb.com)
The simultaneous detonation of three nuclear devices created a crater approximately 700 meters long, 380 meters wide, and 15 meters deep. However, the resulting crater was larger than anticipated, and the unstable slopes led to concerns about the practicality of using nuclear explosions for canal excavation in such terrains.

Environmental and Health Impacts
Despite efforts to minimize radioactive fallout, the Taiga test resulted in detectable radiation levels beyond Soviet borders, including in countries like Sweden and the United States. On-site measurements recorded dose rates of 50–200 R/hr on the crater lip one hour after the explosion. Eight days later, radiation levels up to 5 miles downwind were still twice the natural background levels. (sonicbomb.com)
In subsequent years, the crater filled with water, forming what locals refer to as “Atomic Lake.” While radiation levels have decreased over time, they remain elevated, and the area is considered unsafe for prolonged exposure. Nonetheless, some locals reportedly fish in the lake, and scavengers collect metal remnants from the site. (Reddit)

Conclusion
The Taiga nuclear test stands as a stark reminder of the lengths to which the Soviet Union was willing to go in its pursuit of grand infrastructural projects. While the idea of using nuclear explosions for civil engineering was not unique to the USSR—similar concepts were explored under the U.S. Project Plowshare—the environmental and health risks ultimately outweighed the perceived benefits. Today, the remnants of the Taiga test serve as a cautionary tale about the unforeseen consequences of harnessing nuclear technology for peacetime applications.(sonicbomb.com)
