South Africa is a country which is experiencing freshwater challenges in term of water quality management (DWAF 2005, Ninham Shand & Arcus Gibb, 2001). The challenge in managing this natural resource is often due to an increaase in demand for water by a diversity of land use within the river catchment, which have impacts on water quality (Feng, 2005; Ma, 2005; Rui Li, 2005). The Bottellary River catchment in Cape Town and the Western Cape Province of South Africa is a true example of the impacts that land use types pose on the water quality in this area.
