Heidsee Lake lies in Lenzerheide Holiday Region. This area is in the Vaz/Obervaz community, which also covers Lain, Muldain, Zorten, along with Lenzerheide and Valbella. Romansh and German are the local languages in the region. The dialect is known as Surmiran

Approximately 600 meters by 900 meters, the mountain lake is 41 hectares in size. Originally, the lake was a result of glacial meltwater. It was Johann Brügger-Battaglia and his son Georg Brügger-Vieli who enlarged the lake and built a small fisher hut named Island Chalet.

It is an interesting lake in that it has two parts. Separating both parts is a dam built from 1917 to 1919. Apparently, this dam raised the lake’s level by 1.7 meters and caused major changes to the lake’s landscape. This dam also provides a walkway that leads to a parking lot on the other side of the street. 

The city of Zurich uses the lake to generate electricity.

Since then, various conservation efforts have ensured that the lake remains intact. In fact, the marsh here has become a botanical rarity. Trout, crappies, and other kinds of fish live in the lake. Between June 1st and October 15th, fishing is also permitted.
