On May 20, 2022 WasserCluster Lunz was represented in three locations in Lower Austria (ISTA Klosterneuburg, Universität für Weiterbildung Krems, BAW Petzenkirchen) at the Lange Nacht der Forschung. At the Federal Office of Water Management with our stand on the topic "What lives in the water" we presented algae and animals of the local waters. The visitors could examine them closely and could learn more about their habitats and way of life.
