Grüner See, Mountain lake in Tragöß-Sankt Katharein, Austria.
The emerald-colored Grüner See sits at 776 meters elevation, surrounded by the Hochschwab mountains of Styria with water reaching depths of 12 meters.
Local authorities implemented protective measures in 2016 by restricting all water activities in the lake to preserve its natural characteristics and ecosystem.
The name Grüner See, meaning Green Lake in German, comes from the water's color caused by melting snow from nearby karst mountains.
The lake reaches its maximum depth during mid-May to June when snowmelt fills the basin, making this period optimal for viewing the submerged landscape.
During winter months, the water level decreases to 1-2 meters, transforming the surrounding area into a county park with walkable paths and benches.
