| Sumario: | The San Roque reservoir is 11 km from the city of Carlos Paz and 40 km from the city of Córdoba and one of the functions is to provide water to much of the city and its surroundings. Because it receives a high contribution of nutrients mainly from anthropic activity, it constitutes a favorable ecosystem for the development of algal communities. The general objective of the work was to evaluate the trophic status of the reservoir through eutrophication indices and biological indicators. Seasonal samplings were carried out from February 2014 to February 2016, at the closure wall of the reservoir and the mouth of the tributaries. Physical and chemical parameters were measured and nutrients were determined. The taxonomic identification of the species was carried out, the phytoplankton biomass was calculated using the biovolume and chlorophyll a, and the trophic status index was estimated. A total of 204 Taxa were determined. The dominant component of phytoplankton was the dinoflagellate Ceratium furcoides and as a subdominant the Aulacoseira granulata diatom. According to the trophic status index, we located the San Roque reservoir in a eutrophic state, undesirable conditions in an environment used to provide drinking water. |
