The identification of groundwater sources and the prediction of possible water level fluctuations are crucial, as the study of these indicators is important for understanding the renewal of water resources and their efficient use in specific territorial conditions. The purpose of this study was to identify groundwater sources in the area of Mykulychyn village and assess their changes during the period from 2016 to 2022. The study was based on the Korkmaz method and analysis of data on water level in the well and precipitation level in the study area. The structural analysis of groundwater recharge in the Mykulychyn village in Nadvirna district was carried out using the Korkmaz method. It is established that groundwater recharge in Mykulychyn village is due to precipitation. The correlation between the water flow rate from the source and the water level in the well is demonstrated, allowing for projection of the study results to both objects. The average annual rainfall on the territory was 1,055.7 mm. The results of the linear regression analysis showed a connection between the water level and the total precipitation. The analysis of water level fluctuations in the well revealed that the annual water level recharge varies from 782 mm in 2017 to -254 mm in 2022. This indicates that some smaller aquifers may have dried up in 2022. The average annual recharge for the period from 2017 to 2022 is 347 mm, which is about 32.88% of the average annual precipitation. The results of the study can be useful in practice for water management and planning in Mykulychyn village, as well as in similar geographical conditions
