The present study aimed to develop permanence curves to estimate water availability in the High Pantanal Mato-grossense region. The micro-region is formed by the municipalities Barão de Melgaço, Cáceres, Curvelândia and Poconé, being inserted in the Hydrographic Region of Paraguay, being drained by important watercourses, such as the Paraguay River, Cuiabá River and São Lourenço River, among other tributaries. The data used were related to the historical series of daily flows over a period of more than 30 years, varying between the 1960s and 2019, and which belong to the database of the Water and Sanitation Agency (ANA), National Water Resources Information System (SNIRH). Also, the cartographic bases of the region were consulted to obtain the files with format for geospatial data in vector form, available on the portal of the Brazilian Institute of Geography and Statistics (IBGE). The data referring to flows were organized in Excel spreadsheets and the graphic and analytical procedures for the construction of the curves were performed with the aid of R program. It was concluded that the permanence curves elaborated in this research were adequate, accurate and reliable to evaluate the water availability of the main rivers in the Upper Pantanal micro-region of Mato Grosso, as well as to estimate the flow, according to the frequency of duration. Throughout the historical series analyzed, the stations that had the highest and lowest flow rate were, respectively, Pousada Taiamã (Cuiabá River) and Perto de Poconé (Bento Gomes River). It should be noted that the most stable water availability was observed at the Pousada Taiamã station. The applied methodology was presented as an excellent tool to check the daily flow limits and diagnose the state of the watercourses in the region, assisting in the planning and rational distribution of water resources.
