Glattalpsee
body of water
Glattalpsee is a reservoir on the Glattalp plateau, above Bisisthal, in the municipality of Muotathal, Canton of Schwyz, Switzerland. The lake's water is used by the Sahli powerplant in Bisisthal to produce electricity.
Geography
The surface area is 27.6 ha (68 acres). The lake is located at an altitude of 1,852 m (6,076 ft). Although the lake lies within the canton of Schwyz, it is considered to be part of the Glarus Alps. Its tributaries are the Glattalpseebach, Vorderer Läckibach and Hinterer Läckibach.
The natural lake has no surface outflow. A part of the water seeps through the karst lake bed, while the rest of is used by the Sahli powerplant. Almost half the water that could be used by the powerplant is lost to seepage (up to 700 litres (185 gallons) per second). In order to increase productivity, it is planned to partially seal the lake bed (roughly 12% of the surface area).

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
