About Étang Saumâtre

Étang Saumâtre, also called Lake Azuei, is the largest lake in Haiti and lies in the lowland depression east of Port-au-Prince near the border with the Dominican Republic. The waterbody is saline and supports local fisheries and wetland habitats.

The lake is a focal point for local fishing communities and is important for waterbird populations that use its marshes and shallows. It is a landscape feature of the Cul-de-Sac/Valle de Azua basin and plays a role in local livelihoods and ecology.

Étang Saumâtre sits in Haiti’s Ouest department in the plain bordering the Dominican Republic, forming part of the transboundary lowland that separates the Haitian highlands from the Dominican interior.

  • Alternate name and salinity: Also known locally as Lake Azuei, it is the largest lake in Haiti and is saline rather than fully freshwater.
  • Ecology and use: The lake lies in the Cul-de-Sac/Valle de Azua lowland and is an important habitat for waterbirds and local fisheries.
