Dnieper reservoir cascade
The Dnieper reservoir cascade or Dnieper cascade of hydroelectric power stations (HPP) (Ukrainian: Дніпровський каскад гідроелектростанцій (ГЕС)) is a series of dams, reservoirs and hydroelectric power stations on the Dnieper river in Ukraine. It was created to prevent uncontrolled flooding and improve water transportation infrastructure. Coordination and operation of all dams on the Dnieper is conducted by government company Ukrhydroenergo. In 1970, the Kyiv dam partially prevented flooding in comparison with the 1931 Kyiv flooding.
As with any dam, the water reservoirs of the Dnieper in Ukraine pose a significant threat of a large-scale, human-made disaster if their dams fail. Those concerns were raised in particular in connection with the 2009 Sayano–Shushenskaya Dam disaster. Concerns had yet again been raised regarding an air attack of the Kakhovka Dam on 11 July 2022. The Kakhovka Dam would later fail in the result of an explosion that occurred on 6 June 2023. Flooding will impact downstream communities such as Kherson and will have devastating consequences to communities on the bank of the Dnipro River south of Nova Kakhovka.
To combat uncontrolled flooding, the National Academy of Sciences of Ukraine had developed a program of flooding forecasting; however, as of 2012, the Government of Ukraine refused to adopt it.

Like other reservoirs, Dnieper reservoirs pose a potential threat of causing major flooding if their dams fail. Such damage may be inflicted by a powerful natural disaster (e.g., an earthquake), a human-made disaster, or a deliberate attack by terrorists or enemy forces at war.
The Dnieper reservoirs contain an additional major threat—after the Chernobyl Nuclear Disaster in 1986, radionuclides washed away by rains badly contaminated the bottom silt of the Kyiv Reservoir and presumably the others. During the years following the disaster, there were suggestions to drain the Kyiv Reservoir because it was too shallow.[citation needed]
The dams are supposed to be strong enough to survive natural and terrorist threats. Both their construction schemes and government efforts work towards this goal. For instance, some engineers guarantee that every Dnieper dam will survive an earthquake (to its typical regional extent), meteorite or aircraft falling. There are also countermeasures against overflooding and malfunction of dams. Authorities pay significant attention to safeguarding the dams and bridges by special units of the Ministry of Internal Affairs and other security agencies.
