Northern river reversal

The Northern river reversal or Siberian river reversal was an ambitious project to divert the flow of the Northern rivers in the Soviet Union, which "uselessly" drain into the Arctic Ocean, southwards towards the populated agricultural areas of Central Asia, which lack water.

Research and planning work on the project started in the 1930s and was carried out on a large scale in the 1960s through the early 1980s. The controversial project was abandoned in 1986, primarily for environmental reasons, without much actual construction work ever done.
