Like all Dnieper reservoirs, Kyiv reservoir poses potential threat of tremendous flooding if its dam is destroyed. Moreover, it contains additional major threat - after the Chernobyl Nuclear Disaster in 1986, radionuclides washed away by rains badly contaminated the bottom silt of the reservoir. During the years following the disaster, there were suggestions to drain the reservoir because it was too shallow. It appeared that, if done, this might have created the threat of radioactive dust travelling by wind, possibly affecting Europe.
