Nature obersevers can now download and utilize the CrowdWater app, crafted by the Geographic Institute of the University of Zurich and enhanced with assistance from the KWB. This innovative app allows users to assess lakes by capturing observations and photos of small lakes in Berlin. It gathers data on water levels, quality, and usage. We analyze this information and imagery, providing a valuable database for Berlin's small lakes.
