Untersee (Lake Constance)
The Untersee, also known as Lower Lake Constance, is the smaller of the two lakes that together form Lake Constance and forms part of the boundary between Switzerland and Germany.

Lake Constance refers to three bodies of water on the Rhine at the northern foot of the Alps: Upper Lake Constance (Obersee), Lower Lake Constance (Untersee), and a connecting stretch of the Rhine, called the Lake Rhine (Seerhein). These waterbodies lie within the Lake Constance Basin in the Alpine Foreland through which the Rhine flows.
