Project General Description

The proposed project involves the construction of a dam in Manantali, 90 km south-east of the city of Bafoulabé, in Malian territory. It is a multi-purpose regional development project within the framework of the OMVS global programme. Once completed, the dam will create a water reservoir of 11 billion m3, including 7 billion m3 for the irrigation of approximately 255,000 hectares of land. In the second phase, it is planned to install electrical equipment for the production of approximately 200 MW and 8010 GWh/year. The total cost of the project is estimated at UA 535,948 million. Its implementation will contribute to agricultural development in the three (3) countries: Mali, Mauritania and Senegal and in the second phase will strengthen the supply of electricity to urban and rural areas as well as industrial development in the project area and the navigability of the river.

Project Objectives

The project aims to improve the economic and social well-being of the populations living in the river basin by: (i) the construction of a dam and the creation of a water reservoir to ensure land irrigation in Mali, Senegal and Mauritania; (ii) the regulation of the Senegal River, making it possible for large vessels to navigate by river in all seasons; and (iii) in the second phase, the production of electricity to establish new industries and to provide urban and rural electrification.


The direct beneficiaries of the project are the people and farmers of the city of Bafoulabé in Mali. The project will indirectly benefit the whole country, as well as Senegal and Mauritania.
