During the 1970s, the **Soviet Union** embarked on one of the most ambitious plans in its history: **diverting the course of the great Siberian rivers** towards arid regions in the south, such as **Central Asia** and southern Russia.
The goal was to **convert desert areas** into agricultural hubs, but the chosen method was as radical as it was controversial: **underground nuclear detonations** to excavate thousands of kilometers of canals.
The “Taiga” experiment: when engineering turned nuclear
In 1971, the project reached its peak with the **Taiga experiment**, which involved the simultaneous detonation of **three nuclear charges** equivalent to the bombs dropped on Hiroshima.
The purpose was to divert and connect the basins of the **Pechora and Kama rivers**, but the result was the emergence of the **Nuclear Lake**, a radioactive lagoon in the middle of the boreal forest that still retains contamination levels.
The explosions were detected in countries like **Sweden and the United States**, leading to international condemnation for violating the **Partial Nuclear Test Ban Treaty**.

An ancient idea with a modern boost
The notion of redirecting rivers was not new. Already in the 19th century, thinkers like **Igor Demchenko** envisioned flooding depressions such as those of the **Caspian and Aral Seas** to modify the climate.
Under **Stalin**’s rule and during the **Cold War**, the project took shape as a strategy to **assert Soviet control over Central Asia**, with the support of **200 scientific institutes** and tens of thousands of workers.
Canals of up to **1,500 km** were planned to divert **10% of the flow of the Ob and Irtish rivers** towards republics like **Kazakhstan, Uzbekistan, and Turkmenistan**.
Environmental resistance and the collapse of the project
During the 1980s, the project faced **growing opposition** from scientists, writers, and activists.
Hydrologist **Sergei Zalyguin** denounced the ecological risks: **climate alterations**, loss of unique ecosystems, flooding of cultural sites, and changes in the formation of Siberian ice. The **Chernobyl disaster in 1986** was the final blow.
Four months later, **Mikhail Gorbachev** officially canceled the plan, partly due to environmental pressure and partly due to the **economic crisis of the USSR**.
The persistent legacy of a hydraulic fantasy
Although the project was shelved, its spirit did not disappear. Figures like former Moscow Mayor **Yuri Luzhkov** defended it in subsequent decades.
In **February 2025**, two Russian scientists proposed it again, arguing that technological advances and the **geopolitical shift towards Asia** made it more viable.
Some even suggest that **reducing the flow of warm water to the Arctic** could mitigate climate change, although studies like that of oceanographer **Tom Rippeth** warn that it could **accelerate ice melt** and destabilize the marine ecosystem.
Water as a tool of power: an imperial vision
Beyond its technical justifications, the project embodied an **imperial vision of the territory**: **Russia as a hydraulic power**, capable of dominating not only lands but also **vital resources**.
The idea of transferring water to **China** aligns with the **extractivist model** that has marked Russian history. Historian **Paul Josephson** describes it as a form of **internal colonization**, where public works and Slavic settlements imposed the stamp of the Soviet state on the Central Asian landscape.
The Nuclear Lake: a symbol of boundless ambition
Today, the **Nuclear Lake** remains one of the few visible vestiges of the project. Although radiation has decreased, **some areas remain dangerous**.
Surrounded by mounds and rusty signs, the place is visited by curious individuals like blogger **Andrei Fadeev**, who described it as “beautiful, seemingly peaceful, but with invisible scars”.
The landscape functions as an **allegory of an era** in which attempts were made to **subdue nature with atomic explosions** and turn water into a **tool of geopolitical power**.
