Record-breaking: The white water lily occurs in the entire canton of Graubünden only in the Stelsersee wild and is even said to hold the overall Swiss altitude record.
At the end of the last ice age, enormous natural forces created the conditions for the formation of Lake Stelsersee. Today, the lovely mountain lake is characterized by valuable siltation zones and a rich flora and fauna.
Glacier forces shape the Ur-Stelsersee
More than ten thousand years ago, when the melting of the large glaciers began, the formation of the Stelsersee began. The melting glacier left behind a moraine, behind which a lake dammed up. This original Stelsersee was much larger than it is today.
Over time, the run-off Seebach has become more and more absorbed into the moraine, causing the lake to slowly empty. Only when the stream hit rocky ground, the emptying was stopped. The outflow of the stream and the moraine are still clearly visible witnesses in the landscape today.
From the primeval lake to the moor lake
The constant growth and death of aquatic and riparian plants have led to ring-shaped siltation zones of different sizes and vegetation. Siltation only progresses to a certain depth of water and proceeds very slowly at this altitude. Due to the considerable water depth in the middle of the lake, the open water surface of the Stelsersee has hardly changed in recent decades.
Rare species can be discovered
The Stelsersee is known for its insect diversity. Rare dragonflies with sounding names such as the Little Moss Maiden or the Spear Azure Maiden occur here.
And in the case of plants, many an altitude record can be recorded: In addition to the white water lily, nowhere in Graubünden does the sea braided rush thrive as high up as at the Stelsersee.
Sensitive habitats need our protection
Siltation zones are as valuable as they are sensitive habitats. They are characterized by constant wetting and peat formation. The Stelsersee has an exemplary arrangement of the vegetation zones in the water area. Each zone is characterized by its own vegetation with different species, colors and structures. The wet peat soils around the lake are very sensitive to foot loads and should not be walked on. The input of nutrients can also disturb the siltation zones or make them disappear. Thanks to an unfertilized buffer zone around the lake, this danger is averted here.
How to get to the lake? (Location Schiers, Stels, 1668 m above sea level.M.)
With the Rhaetian Railway to Schiers, then by Postbus to Stels (last stop Mottis) and then in about
50 minutes on foot to the lake.

Pro Natura Graubünden
Since 1947, Pro Natura has been committed to the preservation and protection of the unique mountain lake, and since 1972 the organization has been the owner of Lake Stelsersee. Today, the protected area covers an area of about 7.2 ha.
