The Kleine Ödsee is a forest-lined mountain lake in the Salzkammergut in the municipality of Grünau im Almtal in Upper Austria .
Geography and hydrology
The Kleine Ödsee is located in the Hetzau, a side valley of the Almtal in the Dead Mountains , around 150 m south of the Großer Ödsee .
The small Ödsee is 3.3 hectares in size and up to 14 m deep and is surrounded by steep, densely wooded limestone and moraine banks . The banks slope relatively evenly on all sides, only in the east they are somewhat flatter.
The lake is fed exclusively by underground tributaries. The drainage also takes place underground to the Straneggbach. Like the Great Ödsee, the Kleiner Ödsee has significant level fluctuations over 1 m. The water level normally rises in winter and falls in summer, especially because the surrounding moraine material does not allow inflows during drought and at the same time withdraws water from the lake.
Emergence
The Ödseen lie in the area of the moraines of the Würm glacial period , which go back to the glacier that pulled down from the Prielgruppe into the Hetzau. Moraine remains can be found above the lakes. In the Hetzau there were once lakes in five places, the largest of which probably had an area of over 1 km². While the other lakes silted up , the two Ödseen were preserved because they are protected by moraines from being buried by the Straneggbach.
ecology
The small Ödsee is largely unpolluted due to its location. It has a great depth of view in summer and is classified as oligotrophic . The main species of fish include brown trout , brook trout and arctic char . Like the Great Ödsee, it is designated as a nature reserve ( N013 , 3.2647 ha).
