- Blue algae: First swimming lake in Lower Saxony closed
Due to high concentrations of blue-green algae, the first bathing lakes in Lower Saxony have been closed. Bathing bans are in effect for Lake Westerholt in Wardenburg (district of Oldenburg) and the Großer Ricklinger Teich in Hannover, as announced by the State Health Office. It is also advised not to let dogs drink from these lakes.
For around a dozen other water bodies in Lower Saxony, the Bathing Water Atlas is issuing warnings due to blue-green algae. Cyanobacteria, also known as blue-green algae, can produce toxins that can be harmful through water contact or ingestion. Symptoms such as nausea, diarrhea, inflammation of the nasal and eye mucous membranes, and skin rashes can be caused, according to the reports.
A bluish-green discoloration indicates bacteria
Blue-green algae mainly appear in standing waters during the summer months with high water temperatures. A bluish-green discoloration of the water and the formation of streaks indicate the bacteria. During the official bathing season from May 15 to September 15, employees of the health authorities regularly inspect the bathing lakes.
Dogs should avoid drinking from the closed bathing lakes due to blue-green algae. The presence of blue-green algae in various water bodies in Lower Saxony has led to warnings in the Bathing Water Atlas.
