Chiemsee is a freshwater lake in Bavaria, Germany, between Rosenheim, Germany, and Salzburg, Austria. It is often called the Bavarian Sea. The rivers Tiroler Achen and Prien flow into the lake; the river Alz, out of it. The Chiemsee is divided into the bigger, north section, in the northeast, called Weitsee, and the Inselsee, in the southwest.
The region around the Chiemsee is Chiemgau and is a famous recreation area.
The Chiemsee was formed, like many other pre-alpine lakes, at the end of the last ice age about 10,000 years ago from a hollow carved out by a glacier. Originally the lake covered an area of almost 240 km�, which is about three times its present area. Within 100 years its area shrank to around 200 ha. Before 1904 the water level was lowered by about a metre. As a result, large areas of dry land were reclaimed.
