| description |
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. |

El embalse San Roque se encuentra a 11 km de la ciudad de Carlos Paz y a 40 de la ciudad de Córdoba y una de las funciones es brindar agua a gran parte de la ciudad y sus alrededores. Debido a que recibe un alto aporte de nutrientes provenientes principalmente de la actividad antrópica constituye un ecosistema favorable para el desarrollo de comunidades algales. El objetivo general del trabajo fue evaluar el estado trófico del embalse a través de índices de eutrofización e indicadores biológicos. Se llevaron a cabo muestreos estacionales desde febrero de 2014 hasta febrero de 2016, en el muro de cierre de embalse y la desembocadura de los tributarios. Se midieron parámetros físicos y químicos y determinaron nutrientes. Se realizó la identificación taxonómica de las especies, se calculó la biomasa fitoplanctónica mediante el biovolumen y clorofila a y se estimó el índice de estado trófico. Se determinaron un total de 204 Taxa. El componente dominante del fitoplancton fue el dinoflagelado Ceratium furcoides y como subdominante la diatomea Aulacoseira granulata. De acuerdo al índice de estado trófico ubicamos al embalse San Roque en estado eutrófico, condiciones indeseables en un ambiente utilizado para provisión de agua potable.
