The Westensee was formed as a tongue basin at the end of the last ice age, the Weichselian Ice Age. Dead ice and excavation by the glacier caused the chambering of the lake basin.[1] The basin is surrounded by high terminal moraine ridges. In the south it is bordered by the Tüteberg (height 88 m above sea level).

The construction of the Kiel Canal at the end of the 19th century led to a reduction in the water level of the lake by around 75 cm. The former shoreline is still visible in many areas of the shore. The areas that were dried out by the reduction are now mostly swampy and overgrown with marshland. In particular, the nearby peat lake has now completely disappeared.
