Resumo: 	Fresh water systems are very important to men. They are used to diferents things like drinking water to humans, recreational bath and fishing culture, because of that, a good water quality is necessary and depends on its uses. Besides pathogens and sewage waters, contamination by organic mater could be so bad, resulting in death of water bodies. This can extinguish the disolved oxigen, which is a vital element for the development of the organisms that live in that water bodies. To study the contamination in Ejercito Rebelde dam from October 2005 to January 2006, it was used the saprobic system and protozoans as bioindicators of organic matter contamination. Were identificated 59 species of protozoans, in which ciliates represented 74,5 % of especies’s total. Coleps hirtus (Müller, 1786; Nitzsch, 1827); Litonotus lamella (Müller, 1773); Cyclidium glaucoma (Ehrenberg, 1838) and C. citrullus (Müller, 1786) were considered as good bioindicators, since they kept their habitat fidelity where always they have described, during the evaluated period. Pantle and Buck´s calculated index, placed this dam in the category alfa-mesosaprobic of the saprobic system, indicating high contamination by organic matter. The behavior of Coleps hirtus and cinetochilum margaritaceum showed that the principal organic material contaminant of the dam, had a vegetable origen.
