On 3 August 2021, Parliamentary State Secretaries Uwe Feiler (BMEL) and Dr. Michael Meister (BMBF), Brandenburg’s Minister of the Environment Axel Vogel (MLUK), and several municipal representatives gathered at IGB’s Stechlin site. They all wanted to find out first-hand about the state of the lake, which had recently raised concerns on account of sharply increased levels of phosphorus and oxygen depletion in the lake’s deep water.
