It has an area of 107.8 km², being approximately 21 km long and 7 km wide. The natural outlet for excess water is the Ombilin river which flows eastward to the Strait of Malacca.
A hydroelectric project however has diverted most of the lake outflow to the Anai river which flows westward into the Indian Ocean near Padang. This Singkarak power station uses this water to generate power for the West Sumatra and Riau provinces. A species of fish called ikan bilih (Mystacoleucus padangensis) is endemic to the lake, and is harvested for human consumption. A railway line, which connects Padang and Sawahlunto-Sijunjung, skirts the length of the lake on the eastern side.
Lake Dibawah (Indonesian: Danau Dibawah, means: Lower Lake ) is a lake inWest Sumatra, Indonesia. It is located at 1°0′35″S 100°43′51″E. This lake together with Lake Diatas, are known as the Twin Lakes (Danau Kembar).
Lake Poso (Indonesian: Danau Poso) is a lake in Central Sulawesi, Indonesia, and the third-deepest lake in the Indonesia. The lake contains silver and yellow eels and two endemic fish species, Adrianichtys kruyti and Xenopoecilus poptae. The town of Pendolo is situated at the southern end of the lake, the town of Tentena is located at the northern end, while a number of smaller villages dot the shoreline. The lake drains into the Poso River at Tentena, which flows into the Molucca Sea at the town of Poso. A park containing wild orchids is located near the village Bancea on the lake. As well the forests surrounding the lake still provide rare sightings of the anoa (dwarf buffalo) and the babirusa (literally, pigdeer), a ruminant pig. These two endangered species are among a number of wildlife species found only on the island of Sulawesi.
Lake Toba (Indonesian: Danau Toba) is a lake and supervolcano, 100 kilometres long and 30 kilometres wide, and 505 metres (1,666 ft) at its deepest point. Located in the middle of the northern part of the Indonesian island of Sumatra with a surface elevation of about 900 metres (2,953 ft), the lake stretches from
2.88°N 98.52°E to 2.35°N 99.1°E
.
It is the largest volcanic lake in the world. In addition, it is the site of a supervolcanic eruption that occurred 69,000-77,000 years ago, a massive climate-changing event. The eruption is believed to have had a VEI intensity of 8. This eruption is believed to have been the largest anywhere on Earth in the last 25 million years. According to the Toba catastrophe theory to which some anthropologists and archeologists subscribe, it had global consequences, killing most humans then alive and creating a population bottleneck in Central Eastern Africa and India that affected the genetic inheritance of all humans today.
Lake Matano (Indonesian: Danau Matano), also known as Matana, is a natural lake in South Sulawesi, Indonesia. It is the deepest lake in Indonesia (ranked by maximum depth), and the 8th deepest lake in the world. It is located at 2°29′7″S 121°20′0″E.
Lake Matano is home to many species of endemic fish and other animals as well as many plants. The endemic fishes of Matano have been compared to that of the species swarms of the Rift Valley Lakes of Africa. While not as diverse, they are thought to have all arisen from a single ancestor species and diversified into numerous different species, which now fill many of the previously vacant ecological niches.
