The growing need to have water for various uses, coupled with inefficient management, raises the alarm of a possible overexploitation of the resource, where long-term water resource assurance is urgent. This research seeks to determine relationships between precipitation and its impact on variations in groundwater levels in aquifers, to understand these processes, and determine recharge zones in the basin for the conservation and assurance of hydrogeological resources. For this study, we focus on the sub-basin of the Zaratí River, located in the province of Coclé. Precipitation stations were installed in strategic areas of the basin to measure rainfall, and monthly campaigns were carried out to measure groundwater levels in the study wells. The results show that both for the middle and upper part, as well as for the lower part of the basin, there is a direct relationship between precipitation and variations in groundwater levels. Likewise, some effects of precipitation are not directly influenced in the variations of some wells, however, this is possibly due to the extraction of groundwater from active wells in the area, as well as due to the use and type of soil in the region.
