#jezioropowidzkie #diving #tomekdiving In 2023, scientists took new measurements and designated Lake Powidzkie as the cleanest lake in Poland. A white or black-and-white disc with a diameter of 30 centimeters, called a Secchi disc, is used to measure water transparency. It turned out that the disc became invisible only at a depth of 10.38 meters. The water in Lake Powidzkie changes its clarity several times a year. While it was "crystal clear" when it was measured, we're now presenting the situation and what's at the bottom. Want to support my expeditions?
