In addition to the temperature, information about the water quality, the depth of sight, and the occurrences of different germs are displayed. The germs (Enterococcus & E.coli) are provided in absolute numbers (CFU/100ml) and as a simplified categorization according to the EU's bathing water quality directive (2006/7/EC).
You can switch between a map visualization that displays all the measuring points with their temperature (in degrees Celsius), or an extensive list with filtering and sorting options, e.g. distance from your location, the state the lake is located in, water temperature, water quality, etc. The map also gives you directions to a point of interest and displays the lake's data in a simple infographic.
