Belvedere of the Three Lakes

The “lagoon” colours of these lakes is a result of the formation of a “limestone vegetation ledge” around them. The shallow waters near the bank warm faster. Due to a chemical reaction, “hot” water is less capable of dissolving CO2. More abundant phytoplankton “absorb” the CO2 dissolved through photosynthesis. Water acidity is therefore slightly reduced. These two factors, when combined, mean that the calcite “drips” and forms “white mud”, full of chalk.
