This study used Water Mass Balance approach and IHACRES model to estimate streamflow for ungauged catchment. With the estimated streamflow and socioeconomic scenarios drawn from survey data gathered, the impact of climate change on water resources availability for irrigation in the catchment was assessed using WEAP model. Observed climatic data from four stations were analysed. The study also examined land use/cover changes in the area. The findings showed a rising trend in temperature and potential evapotranspiration. No long-term trend in rainfall data was evident. The study indicates a projected water stressed condition in the catchment due to climate change and rising water demand. Significant decline in land cover over the past two decades was observed.
