The Bilih fish found here cannot survive if moved to other bodies of water, making it a strictly endemic species.
The lake serves as a critical water source for the Singkarak Hydroelectric Power Plant, which contributes significantly to the Sumatra power grid.
It is the second-largest lake in Indonesia by area after Lake Toba.
The lake surface level is influenced by both natural rainfall and technical operations managed for hydroelectric generation.
Local volcanic activity in the Bukit Barisan mountain range historically shaped the basin.
Lake Singkarak is the largest lake in West Sumatra, covering approximately 107.8 square kilometers at an elevation of 362 meters. It is a tectonic lake formed by the Great Sumatran Fault system. The lake is the exclusive habitat of the Bilih fish (Mystacoleucus padangensis), an endemic species sensitive to water conditions. It serves as a major source for the Singkarak Hydroelectric Power Plant, which utilizes water diverted through a tunnel to the Anai River. The surrounding landscape features steep volcanic slopes and terraced rice paddies. The lake is situated within the Solok and Tanah Datar regencies. It remains a key location for regional sporting events, including international cycling tours. The water temperature is generally stable, supporting local artisanal fishing practices using traditional traps.
