Brief synthesisLocated in North-Eastern Chad, in a hot and hyperarid desert setting with less than 2mm rainfall per year, the Lakes of Ounianga comprises a total of 18 lakes, in two groups, displaying a variety of sizes, depths, colorations and chemical compositions. The Lakes of Ounianga property is located in a basin which, less than 10,000 years ago, was occupied by a much larger lake and has a globally unique hydrological system, sustaining the largest permanent freshwater lakes system in the heart of a hyperarid environment. In addition, about one third of the surface of the Ounianga Serir Lakes is covered with floating reed carpets whose intense green colour contrasts with the blue open waters. Wetlands such as the Lakes of Ounianga are also protected by Law 14/PR/98. These activities are implemented with the support of a Local Management Committee, which provides input for improving the existing management plan.
