No signs of harmful blue algae bloom - safe for swimming in the bathing lake

Blue-green algae, also known as cyanobacteria, can pose a risk to both humans and pets when they form blooms in bodies of water. Here's what you need to know about identifying and avoiding blue-green algae in Baden-Württemberg, as well as steps you can take to help prevent their formation.

Recognizing Blue-Green Algae

Blue-green algae can be identified by a greenish-blue, often oily film on the water surface. The water may appear cloudy, sometimes like a soup, and often has a musty or rotten egg smell. If you notice any of these signs, be cautious, especially on hot days and in stagnant waters.

Health Risks and Precautions

If a pet shows symptoms like vomiting, diarrhea, or trembling, take it to a vet immediately. Pets, especially dogs, are particularly at risk from blue-green algae and should be avoided if visible.

If there are no signs warning of blue-green algae, it's important to be vigilant and avoid swimming or drinking water that looks unusual.

Preventing Blue-Green Algae Formation

To prevent blue-green algae formation, one can reduce nutrient input into the water, especially phosphorus and nitrogen. Planting native vegetation along the shore can help filter out nutrients and prevent blue-green algae formation. Encouraging local authorities to implement sustainable water management practices can also help.

Staying Informed

In Baden-Württemberg, the "My Environment" app of the Ministry of the Environment provides information on blue-green algae warnings. The websites of the Ministry of the Environment or local health departments are helpful sources for blue-green algae warnings. The statewide overview on the bathing water map also provides information on blue-green algae warnings.

For the most accurate and up-to-date information, visit the Landesanstalt für Umwelt Baden-Württemberg (LUBW) website, which monitors water bodies in the region and publishes warnings regarding blue-green algae and bathing water quality. Check municipal or regional websites of Baden-Württemberg bath locations, which may also post current water hazard advisories. If online information is unclear, contact local health offices.

Alternatives to Closed Swimming Spots

If a swimming spot is closed due to blue-green algae, indoor swimming pools in the region and rivers with flowing water are alternatives.

Supporting Research and Monitoring Efforts

Supporting research and monitoring efforts can help better understand and manage blue-green algae blooms. Participating in local clean-up efforts and raising awareness about the issue can also help prevent blue-green algae formation.
