Lake Maninjau (Indonesian: 'Danau Maninjau', meaning overlook or observation in the Minangkabau language) is a caldera lake in West Sumatra, Indonesia. It is located 36 km to the west of Bukittinggi, at 0°19′S 100°12′E / 0.317°S 100.200°E.
The Maninjau caldera was formed by a volcanic eruption estimated to have occurred around 52,000 years ago. Deposits from the eruption have been found in a radial distribution around Maninjau extending up to 50 km to the east, 75 km to the southeast, and west to the present coastline. The deposits are estimated to be distributed over 8500 km² and have a volume of 220–250 km³. The caldera has a length of 20 km and a width of 8 km.
Lake Maninjau has an area of 99.5 km², being approximately 16 km long and 7 km wide. The average depth is 105 m, with a maximum depth of 165 m. The natural outlet for excess water is the Antokan river, located on the west side of the lake. It is the only lake in Sumatra which has a natural outlet to the west coast. Since 1983 this water has been used to generate hydroelectric power for West Sumatra, generated around 68 MW at maximum load.
Most of the people who live around Lake Maninjau are ethnically Minangkabau. Villages on the shores of the lake include Maninjau and Bayur.
Maninjau is a notable tourist destination in the region due to its scenic beauty and mild climate. It is also used as a site for paragliding.
