This is the dirtiest pond on the planet. People know it as a “Black Hole”. The illegal mud settling pit of the Dzerzhinsk plant resembles an empty eye socket on the face of the Earth. Fortunately, it is going to be “recultivated” soon which means they will fill it with sand and bulldoze it.
The pond is surrounded with a fence with barbed wire and warning signs, the gates are locked, a lot of rubber boots and gloves are lying about.
However the barbed wire is cut out in some places and one can easily get through.
That boat is used by ecologists, those boards help to get to it.
The lake bottom represents viscous black and yellow muck.
