The Obersee (English: Upper Lake), also known as Upper Lake Constance, is the much larger of the two parts of Lake Constance, the other part being the Untersee (English: Lower Lake). The two parts are separated by the Bodanrück peninsula. The narrow, northwestern branch of Obersee is also called Überlinger See (English: Lake Überlingen).
