**Abstract**

The main objective of this review is to identify and gather most common indicators used to conceive an ecohydrologic index. The research was made by means of a systematic review of different available literature, related to water and ecological indexes. The articles' eligibility was based on studies focused on basins as geographic scale and published in English or Spanish. Additionally, the indexes reviewed must have shown clearly the indicators utilized in their methodology. The selected bibliographic dataset for this study comes from the search strings: water sustainability index, water health index, water risk index, water vulnerability index, water quality index, water sustainability indicators, ecological index, and ecosystem index. The main outcomes resulted in a combination of hydrologic, ecologic, economic, institutional, and political indicators lists. The most repeated indicators on the lists are presented in this document and their ecohydrological relationship is analyzed; as well as the future directions for the realization of an ecohydrological index.
