INMACOM is a river basin organization (RBO) within the Incomati and Maputo Basins (maps attached). Within these, data related to river flow data at strategic points, water quality and reservoir storage levels shared. The data shared is contained in the 2002 Tripartite Interim Agreement between the three member states. INMACOM has a mandate to ensure the equitable, fair and sustainable sharing of water within the two basins.
