Quick Summary

The Trou d’Eau Mountains are part of the Sierra de Neiba range in Hispaniola, corresponding to the Matheux and Trou d’Eau mountains in Haiti. These mountains reach approximately 7,200 feet (2,200 meters) and are located south of the San Juan Valley. Water from the Neiba range flows partly to the Caribbean Sea via the Yaque del Sur river system and partly inland to Lake Enriquillo, which is the lowest point in the West Indies at 144 feet (44 meters) below sea level.1
