A simple model was developed, customized and applied for the Mara River Basin (MRB) to assess water resource availability and demand. Assessment of water resources in blocks of water use using indicators of the growing water demand among competing sectors threatening the sustainability of communities and ecosystems in the basin. The spatial and temporal distribution of water resources and the corresponding demand were quantified. Twelve distinct sub-basins were defined in the basin and their water availability was assessed based on long term rainfall-runoff simulation using the Soil and Water Assessment Tool (SWAT). Water demands from 6 consumptive sectors were divided into 3 classes and compared with a corresponding 3 classes of monthly water availability. Results have shown significant variability of water availability and demand in the MRB. Further study on possible quantitative indicators to redistribute water among stakeholders may assist in improving water management
