Source-derived summary

Lake Tsimanampetsotsa (French: Lac Tsimanampetsotsa) (also called Lake Tsimanampesotse) is a moderately alkaline lake in the Toliara Province, in the southwestern part of Madagascar. It is located at around 24°07′S 43°45′E. The lake is protected within Tsimanampetsotsa National Park and it is also within a Ramsar site. The Ramsar site has a total area of 456 km2 (176 sq mi), while the surface of the lake is much smaller.

The name of the lake in Malagasy means "lake without dolphins". It is a sacred place for worship, ceremonies and rituals. Local taboos prevent water pollution. Swimming and the utilisation of pirogues is prohibited. Water, mud and some plants from the lake are used in traditional medicine (Tahirindraza and Marikandia 2015).

The lake is about 20 km (12 mi) long, about 2 km (1.2 mi) wide and is quite shallow (maximum depth about 2 m (6 ft 7 in)). It is situated in a collapse area of the Mahfaly Plateau, in a closed evaporite basin with cliffs of Eocene marine limestone to the east and a wide strip of alluvium, capping low outcrops of limestone to the west.

Editorial analysis

Why this record matters

“Lake Tsimanampetsotsa” is worth following because a concise public description often conceals a longer documentary argument. Here, Lake, Tsimanampetsotsa and lake provides the most credible route into that argument.

Evidence profile

Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Jul 27, 2026. The linked authority identifier is Q2024048. The first chronological checks are 2015.

Critical limits

Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
