The map shows the distribution of the main reservoirs located within the pluviometric Sahel, based on a consolidated selection of data from Global Dam Watch (GDW) and Global Water Watch (GWW). A total of 523 reservoirs were identified, some of which are located outside the boundaries of the Sahel but are relevant for the control of regional hydrological dynamics. This representation highlights the critical role of storage infrastructure in regulating river regimes, managing floods, and ensuring water availability during the dry season.
