GE-I-6: Contamination of bathing waters by cyanobacteria burdens

The bar chart GE-I-6 ’Contamination of bathing waters by cyanobacteria burdens’ shows the annual number regarding 16 selected bathing lakes according to the extent of burdens for the period from 2003 to 2021. A differentiation is made between: no burden detected, medium burden (maximum 20 per cent of overflights detecting cyanobacteria) and high burden (more than 20 per cent of overflights detecting cyanobacteria). In 2018 six lakes – most of the 16 bathing waters – indicated a high cyanobacteria burden.
