Sumario:The objective was to evaluate the quality of water from basin collector streams in the geographicaldepartments of Federal, Federación, Feliciano and Diamante related to dams for crop irrigation under thehydrological situation of low water. Twelve stream environments were sampled including an inventory ofplant life. Water samples were taken for chemical-physical analysis and for carrying out two bioassays:Allium test and Lactuca sativa seed germination. Root length and germination index, variables recorded inboth bioassays, were analyzed using Dunnet’s test. Streams from Central North of the Entre Rios Provincepresented low sodium adsorption relation (RAS) values (<10) and electric conductivity (EC) lower than 750μS cm-1. In those streams from Diamante Department, EC ranged from 910 to 1170 μS cm-1. The Allium testas well as the toxicity bioassay of Lactuca sativa seed germination were negative. Chemical-physicalanalysis and bioassays indicated aptitude for irrigation and no toxicity in waters from Central North EntreRíos, while those from Diamante department streams though not presenting toxicity, they would not be aptfor crop irrigation during low water season due to high EC.
