The objective of this work was to expand the knowledge on green algae of the tributaries of San Roque Reservoir (San Antonio and Cosquín rivers, Las Mojarras and Los Chorrillos streams) and La Quebrada Reservoir (Colanchanga and Los Hornillos streams). The samples were collected seasonally from 2014 to 2016. A total of 66 taxa were identified: Chlorophyceae (39), Zygnematophyceae (22), Trebouxiophy- ceae (3) and Ulvophyceae (2). The highest species richness occurred in spring and tributary with the highest number of taxa was San Antonio River. The following eutrophication indicator species mentioned are: Actinastrum hantzschii, Monactinus simplex, Nephrocytium agardhianum, Scenedesmus subspicatus, Staurastrum leptocladum, Closterium aciculare and Phacotus lenticularis, an indicator species of environments with calcium carbonate.
