water quality Sonnensee

Sheet 880x322

The Sonnensee forms the center of our naturist family sport and nature camp in Hanover. Excellent water quality has been certified for years. With a size of around 170.000 m², it offers plenty of space for numerous activities. With its clear water and depth of up to 16 meters, amateur divers are also fascinated by our lake. Before and during the bathing season, water samples are regularly taken by the Hanover Region Hygiene team.
The measurement results of the Health Department of the Hanover Region are listed below:
