Abstract: : In Nzoia River, water quality and quantity has been hypothesized to be deteriorating due to human activities in the recent past. Water quantity and quality are highly stressed because of the increase in water demand which is contributed to by the high growth in population, urbanization, food, and energy production. The purpose of this study was to determine the spatial and temporal variation of water quality and quantity as a result of Baseflow filtering using WETSPRO Tool. The study was guided by the following study objectives; To determine the water quality in the upper and lower sections of the river in Nzoia River; determine the flow/discharge rate in different sections of the river in Nzoia River; determine the WETSPRO calibration and validation in Nzoia River and to predict the quality and the quantity of the water in the upper and lower sections of Nzoia River. An experimental research design was adopted during the study. The target population consisted of water samples collected from three sample points in the Nzoia River. The sample size was made of two sample points where the two were selected after meeting the requirement of the dropping from the top of a waterfall in order to create the upstream and downstream. Water Engineering Time Series PROcessing tool (WETSPRO) was used in the analysis of the datasheet. The results revealed, the water quality of River Nzoia ranged from excellent to fair in the downstream direction attributed to increase in pollution levels as evidenced by high water turbidity, poor transparency, low species richness, composition and diversity of the benthic macro-invertebrate fauna. This was due to natural forces and increase in anthropogenic activities. On the discharge rate from different sections of River Nzoia, the study concluded that different sections of the river had different discharge rate.
