Abstract The watershed is the most suitable territorial unit for the economic and social management of the ecosystem goods and services that it provides and its diagnosis must begin with its morphometric description. Cartographic and hydrological material from the National Institute of Statistics and Geography, (INEGI, for its name in Spanish), were used for its morphometric characterization. The analysis and results were obtained through Geographic Information Systems (GIS) and with ArcGis 10.3 software. It has an area of 74.88 km2 and an average slope of 31.69%. It presents a 5 th order dendritic drainage pattern and main stream length of 21.84 km. It is classified as slightly flattened, from oval oblong to rectangular oblong shape, very mountainous and strongly hilly. The results will be used as the foundations for elaborating a program on territorial ordering, water balance and runoff and erosion risks in the micro watershed. Keywords: morphometry, morphometric parameters, concentration time, hypsometric curve.
