Abstract: Predictive modeling of water quality is increasingly becoming a crucial aspect of water resources management as water quality models not only provide an explanation for the transport and transformations of key water quality components but also provide a platform for useful scenario evaluation and testing. Likewise, the use of Geographical Information System (GIS) to support or aid predictive modeling further underlines the versatility and usefulness of GIS as a tool. In this study, a water quality model has been established to simulate parametric concentrations in a natural lake system. The utilization of GIS in the modeling process is described and the benefits highlighted. Among other practical applications, GIS significantly aided model input generation and output display. Output spatial visualization facilitated by GIS, enabled a clearer presentation of spatial variation and progression of water quality components within the lake. This is significant for water resources management purposes as it makes analysis on a spatial and temporal scale easier and also enhances the geographical linkage between pollution sources and areas of impact.
