A pond that always seemed to have been there – swimming pond in Eurasburg
78 m² of swimming space, framed by pale natural stone and boulders: a natural swimming pond at the edge of the woods, two metres deep.

“From the meadow, the pond looks like a natural pond that has always been there.”
A swimming pond at the edge of the woods, and a big one: 78 square metres of swimming space, two metres deep, 200 cubic metres of water. It is framed not by a hard edge but by pale natural stone slabs and boulders that run gently into the water – along with a dry stone wall that holds the slope and large stepping stones that cross one corner of the pond. On the timber deck, sun loungers stand under parasols.
The design is the opposite of a pool: no visible technology, no edge where anything ends, and no colour that looks like a swimming pool. From the meadow it looks like a natural pond that has always been there – and that is exactly the aim with a natural swimming pond.
The installation in numbers
From the project data sheet of our system partner BIOTOP for this installation.
| Swimming area | 78 m², 2.0 m deep |
| Mineral filter area | 78 m² |
| Total volume | 200 m³ |
| Construction | Masonry construction with liner waterproofing |
| Liner | moss green (Sika WT 5300-13C) |
| Surface cleaning | Arc screen skimmer with Oase Aquamax Expert 21,000 |
| Biology | Biological plant filter, filter circuit Oase Aquarius universal Eco 6,000 |
| Additionally | Stream, five underwater lights of 30 watts each |
Why the water looks green rather than blue: because the liner is moss green. This is the most common question about swimming pond photos – the colour comes neither from algae nor from depth, but from a decision made at the drawing board. An anthracite liner would have made the same pond almost black and reflective, and a blue-grey one would have pulled it towards a pool. Moss green lets it blend into the meadow and the woods.
And the proportion: 78 square metres of swimming area, 78 square metres of filter area – exactly half of the system is at work. This puts it between our two other documented ponds: in Bad Tölz the filter area is almost three times the size of the swimming area, while in Berchtesgaden it is roughly balanced, as it is here. With plenty of space, you can swim generously; with little, you gain stability through the filter.
The photos were taken in September 2018. For the construction method, see Swimming Pond; for how to maintain a pond like this, see Maintenance.
