Hamburg, August 4 – The Eichbaumsee in Hamburg’s Bergedorf district is once again closed to swimmers, effective immediately. The Bergedorf district office has issued a ban for the East bathing area due to the presence of blue-green algae. This closure raises concerns about the potential for further restrictions at other popular bathing spots across Hamburg.
Blue-Green Algae: A Growing Concern in Hamburg’s Waters
Currently, warning notices for blue-green algae have also been issued for Allermöher See and Sommerbad Volksdorf. While these locations do not yet have official bathing bans, the Environmental Authority advises caution. “If you cannot see your feet in knee-deep water, do not swim,” is the recommendation from the authorities, highlighting the potential health risks associated with blue-green algae blooms.
Regular Water Quality Checks Underway
According to the Environmental Authority, the water quality of Hamburg’s 14 designated bathing waters is routinely monitored every three weeks. On Monday and Tuesday, district offices collected new samples from several natural bathing areas and lakes. The results of these tests could lead to either an expansion or a retraction of current warnings in the coming days, depending on the findings.
Beyond Blue-Green Algae: Cercariae Also Pose a Threat
In addition to blue-green algae, another concern for bathers in some areas is the presence of cercariae. These are tiny larvae of parasitic flatworms that can cause an itchy rash known as swimmer’s itch. Warnings for cercariae are currently in effect for Boberger See and See Hinterm Horn, as these parasites tend to appear more frequently in warmer water conditions. The Environmental Authority provides up-to-date information on water quality for all bathing areas.
North German Bathing Lakes Generally Clean
Despite these current issues, North German bathing lakes generally boast clean water. Up-to-date maps are available to help residents and visitors identify any current restrictions or warnings before planning a swim. The ongoing monitoring efforts aim to ensure the safety and enjoyment of Hamburg’s recreational waters for all.
The closure of Eichbaumsee serves as a reminder for the public to remain vigilant and heed official warnings regarding water quality. As temperatures remain high, the conditions for algae growth and the presence of cercariae can fluctuate, making it essential to consult the latest information from the Environmental Authority before entering the water.
The situation is being closely monitored by local authorities, who are committed to providing timely updates to ensure public safety. Further announcements regarding the status of other bathing lakes are expected as new test results become available.
