In short: Spanning 128 kilometers, the Moscow Canal was built to solve a desperate water shortage in the 1930s. This massive engineering feat connected the capital to the Volga River, effectively turning Moscow into a maritime hub. Yet, the project was constructed under brutal conditions by hundreds of thousands of gulag prisoners.

By the early 1930s, Moscow faced a severe crisis as its population surged, rendering existing water pipelines insufficient for industrial and residential needs. In June 1931, Soviet leadership approved a plan to divert water from the Volga River, located 120 kilometers north of the city. This decision aimed to secure a reliable water supply while simultaneously creating a new transportation artery for the capital.

Construction began in 1932 and concluded in 1937, directed by the Soviet secret police. The project relied on the labor of the Dmitlag corrective labor camp, which utilized resources from the White Sea–Baltic Canal. Estimates suggest that over 600,000 prisoners were forced to work on the site, with nearly 200,000 present at peak times. Official records document 22,842 deaths in hospital facilities, though this figure excludes those who perished directly on the job or were executed.

The completed canal spans 128.1 kilometers, featuring 11 locks and a minimum depth of 5.5 meters. By linking the Moskva River to the Volga, the canal integrated Moscow into the Unified Deep Water System, providing access to the White, Baltic, Caspian, Azov, and Black Seas. Beyond its role as a transport route, the canal supplies roughly half of the city's water. During the Battle of Moscow in World War II, the canal served a strategic military purpose; defenders flooded surrounding plains by releasing water from the reservoirs to obstruct Wehrmacht encirclement maneuvers.

The canal remains a site of historical memory, marked by a 25-meter statue of Vladimir Lenin in Dubna. A corresponding statue of Joseph Stalin, built at the same time, was removed in 1961 during the de-stalinization era. While the canal successfully met the capital's infrastructure demands, its legacy remains inextricably linked to the immense human cost of its construction.
