Blue-green algae alarm: Cottbus warns against dangerous swimming in lakes!

People are drawn to the outdoors and the warm summer days invite people to go swimming. But there are serious warnings in the lakes around Cottbus. The city has strongly advised against swimming in Lake Branitz and Madlower See due to elevated levels of blue-green algae, also known as cyanobacteria. As the daily news reported, water samples show alarming results: the blue-green algae have multiplied so much that they pose health risks for bathers.

What does that mean specifically? When present in large quantities, cyanobacteria can produce toxic toxins that can cause skin and mucous membrane irritation, diarrhea, vomiting and even allergic reactions. Dogs are particularly at risk because they can become seriously ill when bathing or drinking contaminated water. The Federal Environment Agency points out that, particularly in warm summers, concentrations of cyanobacteria in bathing waters can increase, endangering public health.

Causes of mass development

What promotes these harmful developments? Climate change plays an essential role. High temperatures and stable weather promote thermal stratification of water bodies; these conditions concentrate the cyanobacteria on the water surface. In addition, an excess supply of nutrients such as phosphorus in calm waters creates optimal growth conditions for cyanobacteria. Loud LGL Bavaria The bacteria can not only create ugly water surfaces, but also produce dangerous toxins in high concentrations.

The current situation in the waters around Berlin and Brandenburg is considered worrying. Many lakes have an ecological condition that is worse than the EU requirements. From 2027 there is a risk of sanctions that could be imposed on the region due to insufficient measures to improve water quality. This is not least due to the constant increase in pollutants and increasing overuse of water.

Prevention measures and outlook

Given this situation, it is even more important to be aware of the risks. In particular, warnings regarding blue-green algae should be taken seriously. Skin contact with contaminated water should be avoided and drinking from lakes should be avoided. The best measure is to find out about the water quality before going swimming and avoid any affected areas. Dog owners should be careful not to let their animals into the water to avoid health risks.

The health authorities take measures to monitor bathing waters. This involves taking water samples to be tested for toxins. In many cases, if a cyanobacteria bloom is suspected, a bathing ban can be imposed. The coming weeks could be crucial as warm weather could favor conditions for the further spread of blue-green algae.

Overall, it is important to take good care of your own health and to be particularly careful when it comes to swimming in the lakes in the next few weeks. Avoiding risks is the top priority. A look at the current warnings and regular information could be crucial here.
