Lake Maninjau is a lake in the sub-district of Tanjung Raya, Agam Regency, West Sumatra province, Indonesia. The lake is located about 140 kilometers north of Padang City, the capital of West Sumatra, 36 kilometers from Bukittinggi, 27 kilometers from Lubuk Basung, the capital of Agam Regency.
Lake Maninjau is a volcanic lake located at an altitude of 461.50 meters above sea level. Lake Maninjau is a caldera from a large volcanic eruption that scattered approximately 220-250 km3 of pyroclastic material. The caldera was formed due to the eruption of a composite Strato volcano that developed in the tectonic zone of the Sumatran Fault system called Gunung Sitinjau (according to local legend), this can be seen from the shape of the hills around the lake which resemble a wall. Maninjau caldera (34.5 km x 12 km) is occupied by a lake measuring 8 km x 16.5 km (132 km2). The wall of the Maninjau caldera has 459 m from the surface of the lake which has a depth of up to 157 m (Verbeek, 1883 in Pribadi, A. et al., 2007).
According to the legend in Ranah Minang, the existence of Lake Maninjau is closely related to the story of Bujang Sembilan.
Lake Maninjau is the source of water for a river called Batang Sri Antokan. In one part of the lake which is upstream from Batang Sri Antokan, there is PLTA Maninjau. The highest peak in the hills around Lake Maninjau is known as Puncak Lawang. To be able to reach Lake Maninjau, from the direction of Bukittinggi, you will pass a winding road known as Kelok 44 along approximately 10 km from Ambun Pagi to Maninjau.
This lake is listed as the eleventh largest lake in Indonesia. Meanwhile, in West Sumatra, Maninjau is the second largest lake after Lake Singkarak which has an area of 129.69 km² in two districts, namely Tanah Datar and Solok Regencies. Around Lake Maninjau, there are tourist facilities, such as hotels (Maninjau Indah Hotel, Pasir Panjang Permai) as well as lodging and restaurants.
