In early April, Lake Garda experienced a rare and precious natural phenomenon: total mixing of its waters, which had not occurred in nearly twenty years. The lake initiated a whole circulation process as a result of its unique climatic characteristics, which included constant temperatures between the surface and depth and strong winds. This allowed oxygen to penetrate even the deepest levels, resulting in dramatically improved water quality. Simultaneously, nutrients and trace elements deposited on the lakebed returned to the surface, aiding in the rebalancing of the ecosystem. The acquired results show a significant increase in oxygenation in the depths. This natural "reset" is critical for the lake's health, avoiding stagnation and supporting the survival of deep-water organisms. A rare occurrence, but critical to the future of Garda.
