  ABSTRACT: In the Mayo Bocki watershed, the population’s various water needs are met primarily by groundwater drawn from fractured bedrock aquifers. The aim of this study is to highlight the factors likely to influence hydraulic productivity and to estimate the hydraulic parameters of these fissured aquifers. To this end, the borehole data sheets and the reports on their pumping tests were consulted. The hydraulic parameters were estimated using the method developed by the Inter-African Committee for Hydraulic Studies. The investigation revealed that the flow rates in the boreholes were predominantly low. The productive depths of the bedrock are within the first 50 meters below the surface. Beyond this depth, water inflows become rare. A significant thickness of alteration overlying schist does not improve productivity, whereas in granites and gneisses, it appears to have a positive relationship with drilling rate. Schist is the most productive hydrogeological unit. The average values for the transmissivity and permeability coefficient are 2.7 × 10?4 m2/s and 9.32 × 10?6 m/s respectively. The geological structure revealed by the litho-stratigraphic logs is similar to that proposed by the classic conceptual model in the basement area. These results will help guide any hydrogeological investigations in the study area.
