The average thickness of the ice on the reservoir is about 40 centimeters (16 inches), half what it was in 2011 when heavy flooding prompted officials to abruptly lower the water level of the reservoir. According to the National Radio Company of the Ukraine, the CEO of the company that operates the dam doesn’t expect similar action will be needed this year.
The dam is of particular importance because it sits at the head of a series of dams on the Dnieper River. If it were to fail, the floodwater could potentially overwhelm downstream dams, causing severe flooding in Kyiv and other cities. The dam also receives particular scrutiny because the Kyiv Reservoir contains sediments contaminated with radionuclides from the Chernobyl nuclear meltdown of 1986. The defunct plant is located about 80 kilometers (50 miles) northwest of the dam, and a river that flows near it drains directly into the Kyiv Reservoir.
