Twenty-five years ago, the late B.A. Godana stressed that despite the gap between, on the one hand, the vast number of African international drainage basins and their potential for socio-economic development of the States and, on the other hand, the dearth of international regulations governing water resources, it was noteworthy that the achievements in terms of cooperation were impressive. More than any other African river, the Senegal has been characterized and governed by the most progressive and articulated legal regime. The leitmotif since the inception of this legal regime has been to engage in an experiment that not only follows the most advanced concepts of integrated water resources management, but may also offer lessons in cooperation at the global level. Therefore, the legal architecture to foster cooperation over the management of the Senegal has influenced the development of the law of international watercourses in Africa.
