Considering the economic, social and ecological importance of this resort in particular, it is necessary the performing on routine monitoring in Rio Tercero dam in order to know its trophyc status and water quality. The goals of this work were to evaluate seasonally the trophyc condition of the dam, asses shallow water quality for different uses by means of physico-chemical and phycological analysis, and establish the potential risks for public and animal health. Six sampling stations were considered, two seasonal samplings per chosen site, during 2003-2004. Physical, chemical and biological parameters were assessed using standard methodology. During summer 2004 general characteristics of water were those of freshwater, calcium bicarbonated, low in salts for animals and good for human consumption. According to results observed in sampled sites, the trophyc condition of the dam is mesotrophyc. Phycological counting displayed that, during summer, there was a dominance of Bacillarioficeae over Cyanophyceae, which was not a tendency along the year. Our results demonstrate that the dam is in between the limits suggested by local legislation. Some critical areas receiving effluents should be studied systematically and on bigger scope.
