In September 1935, the USSR decided to build the Rybinsk hydroelectric complex. According to the project, the water level was supposed to rise by 98 meters. But already on January 1, 1937, the project was revised, and it was decided to raise the level to 102 meters. This made it possible to increase the capacity of the Rybinsk hydroelectric power station by one and a half times, but at the same time the area of flooded lands should have almost doubled.
The grandiose construction threatened the existence of the city of Mologa and hundreds of villages and villages in the Yaroslavl region. When the residents of Mologa were informed that soon their small homeland would cease to exist and disappear under water, no one could even believe it. At that time, the district center Mologa had about 7, 000 inhabitants.
The resettlement of residents began in the spring of 1937. Most of the residents of Mologda were sent to the village of Slip, not far from Rybinsk. But some residents stubbornly refused to leave their homes. In the archives of the NKVD, there was a report that 294 people did not want to voluntarily leave their homes, and some of them even threatened to chain themselves with locks. Soviet propaganda attributed this to "mental disorder of the backward elements." According to the instructions of the NKVD, methods of force were applied to them.
On April 13, 1941, near Rybinsk, the last lock of the dam was closed, and water gushed into the floodplain. The city of Mologa, whose history spans almost 8 centuries, has sunk under the water. Its territory was completely flooded in 1947, only the heads of some churches remained above the water, but after a few years they also disappeared under the water.
In addition to Mologa, about 700 villages and villages, with a population of about 130, 000 people, were under the flood. All of them were relocated to other regions.
But sometimes "Russian Atlantis" can be seen. The water level in the Rybinsk Reservoir often fluctuates, and a flooded city appears above the surface of the Volga. You can see preserved churches and brick houses.
The descendants of those who had to leave their hometown do not forget about their roots. Back in the 60s, former residents of Mologa began to hold meetings. And since 1972, on the second Saturday of August, the residents of Mologzhan have been arranging a boat trip to the area of the flooded city.
In 1992-93, when the water level in the reservoir fell, local ethnographers organized an expedition to the city. Interesting materials on the history of Mologa were collected. Many of them became exhibits of the Museum of the Mologa Territory, opened in 1995 in Rybinsk.
