Monitoring water quality parameters constitutes a basic tool to assess environmental changes caused by human actions. The water quality indexes can be used in the interpretation of data, supporting the results evaluation and enabling to compare water conditions over time and in various geographic locations. This study aimed to monitor the water quality of Furninha watershed, located in the municipality of Ourinhos/SP-Brazil. Studying the spatial-temporal variation of water physical, chemical and biological characteristics we tried to characterize the current state of water body and to detect possible changes resulting from anthropogenic and/or natural seasonality. The study area is located in a rural area in the northwest portion Ourinhos and presents several potentially sources of polluting. The study area was divided in five monitoring locations for data collection: Number 1 (spring), Point 2, Point 3, Point 4 (Furninha Lagoon) and Point 5 (outflow of the pond). This systematic monitoring of the area generated large amount of data, which were analyzed for the appropriate investigations and discussed regarding to the water quality in the watershed during the hydrological year of 2010-2011. Water is of acceptable quality as a whole, the most critical points are the ones who suffer the greatest human intervention (Point 1 and Point 2), the seasonal variation is critical to water quality in the Watershed Furninha. With all the tracking done, was given the genesis of a novel database, which should continue in the coming years.
