Lake Poso
Lake Poso is a lake in Central Sulawesi, Indonesia, and the third-deepest lake in Indonesia.
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.Ecology
The lake contains various fish, including the eel Anguilla marmorata which migrates between the lake and the sea, and 11 fish species that are endemic to the lake, notably buntingi ricefish, gobies, and the halfbeak Nomorhamphus celebensis. These endemics are all highly threatened; in some cases possibly already extinct. One of the reasons for the drastic decline of the native fish are introduced, non-native species, particularly Mozambique tilapia and common carp.
There is also a large number of endemic Tylomelania freshwater snails in the lake, as well as several endemic Caridina shrimps and Parathelphusid crabs.
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 and the babirusa, a ruminant pig. These two endangered species are among a number of wildlife species found only on the island of Sulawesi.
