There are nine major rivers traversing the lake Victoria catchment of the Kenya side. The river basin, which ranges from 1000Km2 to 12,842km2 is, characterize by hilly deforested slopes, human settlement and extensive agricultural activities. As the rivers traverse the entire catchment they receive pollutants from point and non-point sources, which are a result of the above activities. The pollutants not degraded find their way into the lake. To assess and characterize the quality of the rivers, two key nutrient parameters and suspended solids were monitored at fifty sampling stations for three years. During the same period river levels were also measured.. Mean Volume weighted concentration were calculated and discharges obtained from hydrological unit were used to calculate the total load to the lake. The results showed that high loads were recorded in the areas with larger catchment area, with dense population and characterized by intensive agricultural activities, while high concentrations were obtained in catchment areas with intensive agriculture hilly bare slopes and eroded falling river banks.Page Range
