The objective of the present work was to analyze the environmental studies and monitoring of aquatic plants in reservoirs of hydroelectric plants to develop a policy for managing these communities for existing and future reservoirs. The literature review and documentary analysis were carried out in search of information on environmental impact assessments, monitoring of each hydroelectric project, books, magazines, special publications, specialized websites and written press, available on the Internet or in libraries. The documents obtained were systematized and the information organized chronologically per undertaking considering the study area, sampling method, time and sampling number. It was found that there is still great difficulty in accessing documents in the hands of environmental agencies. It was observed that monitoring, mainly under an environmental operating license, is not being carried out systematically, leaving important gaps regarding the composition and abundance of species, which makes it difficult to compare their behavior over time. For monitoring studies, different methods were used which influenced the results when an integrated analysis was sought. It is necessary to create procedures and define methods in the environmental licensing process for the systematization of studies and monitoring, to improve the accessibility and allow the integrated analysis of data.
