Austria has an abundance of lakes and rivers. You may find them across the whole country, even at altitude, high up above the tree line. For divers, most of these lakes are only accessible by helicopter. With a gear weighting 50 to 60 kg, caryying it across hundreds of meters of altitude is no option.
Most of the lakes haven’t been dived before. Under water, they’re the white spots on the map. Together with a Group of seasoned mountain lake divers, I dive these lakes. We map them, take water samples and pictures.
