First limnological investigations at Gossenköllesee were undertaken in 1933. A research station was built in 1975 close to the lake, after another research station established in 1959 at close to Finstertaler See had to disappear due to the construction of a hydropower dam. In 1994, the new research station at the lake shore was renovated and modernised.

Numerous master and PhD theses as well as Post-doc studies have been carried out at Gossenköllesee addressing topics like atmospheric deposition, snow chemistry, hydrology, water chemistry, catchment soils, lake ice cover, phytoplankton, zooplankton, zoobenthos, fish ecology, ecotoxicology, microbial food webs, paleolimnology and aquatic photobiology. Project funding comes from the Austrian Science Foundation FWF and the European Commission.
