Did you know?

The Wassermannsee is a former gravel pit whose gravel was deposited by an ancient arm of the Rhine – meaning the river once flowed right through this area before shifting its course.

History

The lake takes its name from the Wassermann company, which quarried gravel here. The material had been deposited millions of years ago by a former branch of the Rhine. After quarrying ceased, the site was left to its own devices and gradually became overgrown over the decades.

Nature and Shoreline

Tall herbaceous plants and reed beds help stabilise the banks. The lake and its embankments remain largely fenced off; fishing is permitted along the water's edge.

Vogelsanger Triotop

The lake forms one part of the three-part Vogelsanger Triotop. This includes a nature reserve encompassing the lake and the near-natural meadow landscape of Wassermannpark, a commercial park, and a natural area featuring a traditional orchard meadow.
