Lake Ihotry at a Glance

About Lake Ihotry

Lake Ihotry is a large shallow lake in southwestern Madagascar’s Atsimo-Andrefana region. The lake’s extent and salinity fluctuate seasonally, producing exposed flats and wetlands that support waterbird populations.

During wetter periods the lake attracts a variety of waterbirds and is used by local communities for fishing and salt collection where conditions allow. Its shallow depth and seasonal dynamics make it different in character from deep permanent lakes.

The lake sits in the semi-arid coastal plain of southwestern Madagascar and is part of a broader system of seasonal wetlands and basins in the region. Surrounding land use includes pastoralism and small-scale agriculture adapted to variable rainfall.

Geographically it is located in southwestern Madagascar, inland from the coastal town of Toliara/Tuléar and surrounded by low-lying plains and seasonal drainage channels.

  • Important for waterbirds: A large, shallow saline or seasonal lake in southwestern Madagascar that provides habitat for waterbirds and local fisheries when levels permit.
