Macun – thriving high mountain lakes

Since 1 August 2000 the Macun plateau and lakes, situated at over 2500 m altitude, are a part of the National Park. Building on earlier scientific investigations, the Macun lakes are regularly inspected.

In the course of these investigations, the development of the water quality in the lakes is studied. The waters of mountain lakes in areas of crystalline rock generally tend to become more acid. In the Macun lakes this has, so far, not been the case. An additional point of interest is whether the brown trout and Canadian lake trout introduced by fishermen in former years are able to survive in the lakes.
