摘要：This work aims to present the water quality assessment of Campestre´s Stream watershed inserted in Lins town limit, in the São Paulo’ State, during the period between mars and december 2002. The water was sampled at seven points of this watershed, and then the physical, chemical and biological parameters were analysed in the university laboratory. Through the seasonality and correlation of physical, chemical and biological parameters with the results of Water Quality Rate (WQR) and the researches on field, were possible to verify that the effects of the main antropics activities (stream channel erosion beside the complete inexistence of riparian zone) developed around these stream caused the nutrients elevation (phosphorus and nitrogen) and the increase of coliform concentration levels mainly in the urban collection points that contributed to the watershed degradation.
