ABSTRACT. Because Tlaxcala State (TS) is one of the smallest and limited states in Mexico, new agricultural development programs by the government will be applied to enhance quality of life of its population. Therefore, groundwater demand will be increased, causing pressure in available aquifers. By law, four aquifers were defined by the government which are: a) Soltepec Aquifer 2902 (SA) on North West of TS, b) Atoyac-Zahuapan Aquifer 2901 (AZA) in the Center, c) Emiliano Zapata Aquifer 2904 (EZA) in Northeast and d) Huamantla Aquifer 2903 (HA) in the East. According to CONAGUA 2015, results of water budgets analysis have presented following results: a) SA, 88 wells with water availability of 34.52 million of cubic meters per year (mcmy), b) AZA, 720 wells with water availability of 46.88 mcmy, c) EZA, 27 wells with water availability of 0.61 mcmy and d) HA 234 wells with water availability of 19.14 mcmy. This paper presents a hydrometric analysis of water levels in wells using long term view hydrograph for 10 years (2008 to 2017) to describe future water levels decline in aquifers and its behavior. All findings of this work will aware users and government TS administrators to develop and to supervise proper rules to avoid the over pumping water from aquifers in order to maintain sustainable underground resources, although water budget still presents availability of water for pumping, there are trends in declining water levels to depletion in future.
