Lake Piburg

Lake Piburg is a mountain lake at 913 m of elevation, situated on the western slopes of the Ötz valley above Ötz. The lake is about 14 hectares large and has a maximum depth of 25 meters. Research at this lake started in the 1930s with limnological monitoring performed since the 1960s and 70s. Intensive recreational use and close by agriculture lead to eutrophication of the lake, which was repaired through an Olszewski tube installed in 1970. Today, the lake is oligo-mesotrophic.

The main research infrastructure at the lake is a floating platform equipped with a weather station and sensors measuring water temperature, conductivity, O2 and pH. This platform works all year round with online data transmission.

The data gathered is used for research on bacterioplankton, mixotrophic flagellates and copepods as well as the stratification of the lake and its changes under climate influences.

Lake Piburg is part of the LTSER platform Tyrolean Alps within the international LTER (Long-Term Ecosystem Research) network and a training location for students of the University of Innsbruck.
