Haffstausee
The Haffstausee was a body of water made of glacier melt water in the area of today's Ueckermünder Heide at the end of the last ice age . The northern glacier prevented the water from flowing away. Today's Baltic Sea was 36 meters lower. Meltwater from the inland ice, thaw water from the surrounding dead ice areas and river water from the southern area collected in the Haffstausee. The meltwater flows led to the rise of the lake level and a maximum extension of 1200 km².
After the ice had receded, the lake water flowed off at different times via three channels, which are now formed as glacial valleys : the Mecklenburg-Western Pomerania border valley , the Peene valley and over Ziese and Strelasund .
The gradual runoff created terraces and valley sand steps in the landscape. Lake chalk and basin sands from the lake at that time can still be seen today in the soil stratigraphy .
