Postsee

Divided lake

The post see (formerly also Pastsee ) is a lake west of the city Preetz in the district of Plön, in Schleswig- Holstein. It extends in the southwest - northeast direction.

Naturally, there is the post see from a northern and southern basin one, between which there was a Seeenge at Waldsieversdorf. During the construction of light railway Kirchbarkau - Preetz Luetjenburg a dam there was heaped up and built a bridge. After degradation of the railway in 1938 this way is only used by cyclists and pedestrians. Its most important tributary, the Old Schwentine ( Kührener Au ) opens, east of Post field in the south, leaving the northern part in Preetz and eventually flows into the Schwentine.

The lake in 1915 was given as 341.7 ha, has thus been reduced by about 65 ha. This is partly due to siltation, but also partly to the lowering of the lake level, which has been pursued in the 19th century. The water level in 1915 is 21.5 m above sea level. NN indicated, and therefore is about 80 cm above the current one.
