Quagga
The Quagga–mussel has been first observed in Lake Constance in 2016. Five years later, the aggressively invasive species is omnipresent, populating lake floors from the shallow water zones down to the deepest lake floors. Observations made in the framework of monitoring works of the Landesamt für Denkmalpflege, Dienststelle Hemmenhofen and the "Informationszentrum Pfahlbauten Baden-Württemberg" indicate that the world famous prehistoric settlement sites in the shallow water zones of Lake Constance are increasingly inflicted.

Frost Heave
Frost heave (German: Frosthebung, Frosthub) is a natural process well known to geologists and constructional engineers. It results from ice forming beneath the surface of soil during freezing conditions in the atmosphere. The physical phenomenon is closely connected to frost-susceptible, water-saturated soils. It causes considerable losses of underwater archaeological evidence at the shores of non-regulated pre-alpine lakes. At Lake Constance (D/CH/A) large areas of the shallow water zones fall dry in winter times, causing pile heads to “grow” from the frozen lake beds, freeze, and get subsequently destroyed .
