Schmiechener See, Protected wetland in Schelklingen, Germany

Schmiechener See is a shallow lake formed within an ancient Danube River meander, covering around 50 hectares at high water levels. The protected area includes reed beds, open water surfaces, and surrounding meadows that create a varied landscape.

The lake was formed naturally when the Danube River changed its course over earlier periods. The area was officially protected in 1973 after scientists recognized its critical role as a habitat for water birds and other wildlife.

The local name 'd'r Sai' comes from the regional dialect and shows how deeply connected the surrounding communities feel to this water. Visitors often hear residents use this term, which reflects the everyday relationship people have with the place.

The reserve lies southeast of the Schmiechen district of Schelklingen in the Alb-Donau district. The lake has no outflow; its only inflow is the Siegenbach. In dry years the basin can dry out except for a few damp spots, so water levels and the extent of open water vary greatly between visits.
