Lake Itasy is a lake in central Madagascar. It is located in Itasy Region. It is situated in the municipalities of Ampefy, Soavinandriana, Manazary and Analavory.[1]
Lake Itasy has an area of 3,500 hectares. It is the fourth largest lake on Madagascar, after lakes Alaotra, Kinkony, and Ihotry.[2]
The lake has an average depth of 4 meters, and reaches up to 10 meters deep. The water level varies seasonally. There are marshy areas in the southern and eastern parts of the lake.[3]
Lake Itasy lies in the volcanic Itasy Massif. The volcanic activity in the region is relatively recent, and lake was formed when lava flows blocked a river, forming a lake behind it. The landscape around the lake is covered with Strombolian scoria cones and trachyte domes. The volcanic landscape around the lake has many smaller lakes (maars) and peat bogs.[2]
The Andranomena and Mariandrano rivers empty into the lake from the east.[3] The Lily River is the lake's outflow, draining westwards from the northwestern corner of the lake. The Lily is a tributary of the Sakay River, which is a tributary of the Tsiribihina River. The Tsiribihina flows westwards to empty into the Mozambique Channel.[2]
