description Background and aims: The drainage system in the Alto Valle of Río Negro (Argentina), is integrated by a network of drains, and was designed to collect excess irrigation water from agricultural establishments. This artificial aquatic ecosystem allows the development of vegetal herbaceous species. The progress of urbanization towards agricultural lands increased the use of drains, due the discharge of industrial and urban effluents. The increase in non-agricultural effluents contaminate these environments producing changes in biota abundance and diversity. This work aims to propose the syntaxonomic categories of vegetation associated to the drainage system and determine the relevance of vegetation as a biological indicator in environmental impact studies. M&M: Floristic censuses obtained in previous vegetation studies were used and complemented with new surveys carried out during the period 2018-2019. Census were carried out with the phytosociological school of Zürich Montpellier methodology. Results: The syntaxa found are described, according to the final phytosociological table interpretation. Its floristic, structural, syntaxonomic aspects and its potential as contamination bioindicator are discussed. Conclusions: Twenty-eight syntaxonomical categories were established: three classes; Five orders, five alliances, two sub-alliances and thirteen associations for the Alto Valle drainage system, organized according to three growth habits: floating, submerged and emerging aquatic. 80% of the associations have eutrophication bioindicator potential in the Alto Valle de Rio Negro drainage system.
