A very special lake in the Alps
Today, we present a very special “lake”. In winter, it serves
as a water storage for snow cannons; and from spring to late autumn, it
becomes a lake for divers. The Grüblsee is probably Austria's most
unusual “watering hole”, complete with Europe's highest dive centre.
The incredible variety of fish and fabulous visibility make it an
“alpine aquarium” in the Upper Styria.
The Grüblsee is an artificial lake, nine metres deep. With foil as
floor cover. Almost no water plants. Sounds like a boring lake? Far
from it! The lake's main attraction are the fishes. Hundreds of them
approach and surround may the diver in a feeding frenzy. Why? In this
lake, on a special platform, divers are allowed to feed the fishes from
a small capsule containing food. Once the capsule is open, mayhem (to
put it lightly) ensues. Then, after all scraps of food are consumed,
calm once again returns to the platform – well, till the next diver
descends, that is!
The lake also contains a number of statues positioned along a course in
the shape of a figure eight along a line mounted on the ground. Other
highlights of the lake comes in the form of sturgeon, the largest of
which are 180 cm long.
When in the lake, it is important to maintain your buoyancy and to be
mindful about your finning techniques. This reduces the possibility of
stirred-up mud and silt affecting the visibility of the water.
In winter, the water level in the frozen and snow-covered lake
decreases by three to five metres, due to the mobilisation of
snowmaking equipment. During this time, the diving centre turns into a
Although the flora is limited to just a few aquatic plants, there is a
large variety of fish – as many as 500 fish of 14 different species in
the small lake.
At the lake you will find the diving school Präbichl, run by Robert
Marschnig and Sabine Hausner. Registration is required! The 2017 season
starts this weekend..
If you want to visit the Alpenaquarium Grüblsee to see the fishes in
the near future, you should register in advance, as the permitted
number of divers every day is limited.
The owners, Sabine Hausner and
Robert Marschnig, look forward to your visit and will be happy to tell
you more about the exciting underwater activities over a meal and a
glass of wine from the kitchen of their own restaurant.
