Green Lake in Tragoess in Austria doubles in size from 2000 square metres to 4000 square metres every spring when the snow in the surrounding Karst mountains melts. The result is that the surrounding trees, benches and bridges around the lake are submerged by its growth as its depth rises from one metre to just over twelve. The result is an eerie underwater world, which is equal parts creepy and beautiful.

Diver Marc Henauer from Switzerland heard about the phenomenon and decided to head over there with his wife for a week to take a bunch of sick photographs, the results of which you can see below and on the following page. There’s also a short video about it that you can check out too.

On his experiences photographing the area, Henauer offered the following statement:

‘When I was underwater, it felt like I was swimming in a magical world, it was so beautiful. Swimming over the green grass, flowers, paths, rocks and trees was like being in a fairy tale. We were lucky that the sun created fantastic light rays through the water. My wife and I stayed there for seven days and we did three dives every day, spending one hour on each dive’.

‘All pictures were taken in natural light without a flash. I am very delighted with the result because we had a lot of problems with the heavy rain, thunderstorms and wind. We only had a very short time to take images when the sun was in a perfect position. Diving is possible only for a month in the spring. Throughout the year the depth of the lake is too low. The visibility is just incredible. Usually you only see water like that this in tropical seas’.
