How Russia Weaponized a River in Ukraine

Twice in one lifetime, the same river was turned into a weapon. In 1941, the Soviet Union dynamited its own dam on the Dnieper to slow the German advance, and the flood it unleashed drowned its own civilians and its own soldiers downstream. The death toll was never counted, and the whole thing was buried for almost fifty years. In 2023, the Kakhovka dam on that same river was destroyed again, draining the largest reservoir in Ukraine in a matter of days and causing one of the worst environmental disasters Europe has seen in decades. This is the story of one river, two catastrophes, and what an engineer sees that a general doesn't: a dam is the only ordinary structure that holds enough stored energy to devastate a region in minutes, and when you let it loose, the water never asks whose side you're on. I'm Sean, a licensed hydropower engineer, and on The Hydraulic Record I break down how our water infrastructure fails, and why. This one was heavier than most, and I tried to treat it with the care it deserves.

Russia denies it. Because the site is occupied, a signed forensic verdict may never exist, but the evidence is clear enough to say what the evidence says. The peer-reviewed work below also shows the structure was already failing beforehand, which deepens the picture rather than muddying it.
