About 50% of South Africa’s biggest dams could be dangerous to those who swim in them. South African dams have high levels of cyanobacteria, a type of algae that feeds of nutrients such as fertiliser and sewage run-off.
South Africa is in the middle of a potential wet season as heavy rainfalls continue to fall over large parts of the country, making a significant improvement in the country’s water situation.
Most parts of South Africa, specifically its summer rainfall areas, have received above average rainfall since October 2021. This has led to an increase in the country’s national average water levels.
Winter is coming, but it looks set to be mild.
