Moravian Karst cave divers likely locate Punkva River source

Cave divers exploring the Amatérská cave in the Moravian Karst have likely discovered the location where the Sloupský stream and Bílá voda merge to form the Punkva River. This connection was previously unconfirmed.

During the expedition, divers navigated a narrow, 50-meter passage under the Rodeo dome, successfully linking sections they have been attempting to connect since 2020. Radek Nejezchleb, chairman of the speleological organization Plánivy, noted that the discovery was made after noticing an inconspicuous branch with clear water, distinct from the murky Bílá voda.

To provide definitive scientific confirmation and rule out earlier mixing of the water sources, researchers plan to conduct dye testing in consultation with experts from Charles University. They also intend to install measuring sensors and trackers in the cave system during the upcoming winter.
