The water of the lake was partly drained through the tunnel through the Bukit Barisan to the Batang Anai Singkarak hydropower generators to drive near Lubuk Alung, Padang Pariaman.

Fish Bilih (Mystacoleucus padangensis) is a species of fish are expected to live only in this lake [1], and became one of the typical food. Research experts revealed 19 species of fish live in freshwater aquatic habitats of Lake Singkarak, Solok and Tanah Datar regency, West Sumatra (West Sumatra), with the limited availability of food ingredients. Of the 19 species, three species of which have high population density, namely fish Bilih / Biko (Mystacoleusus padangensis Blkr), Asang / Nilem (Osteochilus brachmoides) and Rinuak. Other fish species that live in Lake Singkarak is, Turiak / turiq (Cyclocheilichthys de Zwani), Lelan / Nillem (Osteochilis vittatus), Sasau / Barau (Hampala mocrolepidota) and Gariang / Tor (Tor tambroides).

From a few times and showed betos plankton in Lake Singkarak is very low.

Whereas plankton communities (phytoplankton and zooplankton) is the basis of the formation of a food chain and plays an important role in a lake ecosystem. Under these conditions, causing a major source of nutrients naturally fish generally are the various types of plankton and benthos. Lake Singkarak is at the geographical coordinates of 0, 36 degrees South Latitude (LS) and 100.3 east longitude (BT) with a height of 363.5 meters above sea level (masl). Water surface area of ​​Lake Singkarak reached 11,200 hectares with a maximum length of 20 kilometers and 6.5 kilometers wide and a depth of 268 meters.
