Lake Enriquillo, the largest lake and the lowest elevation in the Caribbean, is located in the Dominican Republic.
Step-by-step explanation:
Lake Enriquillo is the largest lake and the lowest elevation in the Caribbean. It is located in the country of the Dominican Republic which shares the island of Hispaniola with Haiti.
The lake is situated in a rift valley formed by the Enriquillo-Plantain Garden fault system and is known for its high salinity levels, which exceed that of the ocean, and its populations of American crocodiles and unique species of fish. This saline lake is also significant as it is the largest lake in both the island of Hispaniola and the entire Caribbean.
