2.1 Description

The Lake Azuei measures 170 km² in surface area. It runs along the axis Northwest - Southeast over a length of 24 km with 12 km wide. It has a depth of respectively 24 meters 60% of its area and 5 meters deep and 35% of its area with a strip of 500 meters wide deep from zero to five feet. The lake has approximately a volume of 2465 km³ or 2465 10⁹ m^{3 1(*)}.

2.1.1 Geographical coordinates and location

Lake Azuéi

Figure I: Map of Haiti and Lake Azuei

Azuei Lake is located on the arid valley of Cul-de-Sac, East Port-au-Prince in the department of the West (Figure I). It is located at 30 km from Port-au-Prince 18 ° 35'31'' North Latitude and 72°00'53'' West Longitude (Pierre, 1980).

* ¹ This volume is obtained by multiplying the average depth (24 m + 5 m / 2 = 14.5 m) by the surface area (170 km²) of the lake. Note, that these data can be changed if the shape of the bottom is poorly estimated.
