Site summary
A shallow bay on Lake Constance with a mainly artificial shoreline. The Swiss part of a transboundary IBA together with the German IBA «Lake Constance-Obersee, and the adjacent

The site holds 20’000 or more waterbirds in winter, on a regular basis (includes Tufted Duck 2’500-5’600 individuals). The site only fulfils criteria if the Swiss and German IBA are considered together.
