Swimming Warning
There is currently an increased presence of cyanobacteria (“blue-green algae”); please follow the on-site guidelines regarding this.
Under current summer conditions, depending on wind and wave conditions, accumulations may occur, for example, in beach areas. These areas should be avoided, and children in particular should be supervised.
Caution should also be exercised with regard to dogs swimming.

Steinhude Beach Island Information Profile
Lake Steinhuder Meer is designated as a landscape conservation area and is surrounded by several nature reserves. The lake is largely fed by groundwater. Additional water flows into the lake via four tributaries. Additional water flows into the lake via four tributaries. The towns of Steinhude and Mardorf, located on the lake, discharge rainwater into the Lake Steinhuder Meer via a separate sewer system. Rainwater also carries debris into the lake, which may contain bacteria. During heavy rainfall, these bacteria can reach the swimming area and affect the quality of the bathing water.
Due to the aforementioned discharges, the pollution potential is assessed as slightly elevated.
Because of the high nutrient content in the lake, mass blooms of blue-green algae occur frequently. The potential for a mass bloom is considered to be elevated to high.
No mass proliferation of macroalgae or phytoplankton has been observed in the water body in recent years. The potential for mass proliferation is classified as low
.
The Department of Health, as the responsible authority, conducts regular tests of the bathing water at the swimming area.
The first bathing water sample is taken before the start of the season.
During the swimming season, from May 15 to September 15, samples are taken once a month. The water is tested for the indicator bacteria Escherichia coli and intestinal enterococci. These results are published, among other places, on the website www.hannover.de/baden and on the bathing water portal of the Lower Saxony State Health Office.
If the authorities become aware of a blue-green algae bloom, they will test the water for blue-green algae and issue an official warning regarding the acute occurrence
of blue-green algae. If large quantities of toxin-producing blue-green algae are detected, a swimming ban will be imposed and announced both on-site and online.
