The dynamic climate changes observed in the last few years contribute to a more frequent occurrences of extreme natural phenomena e.g. droughts or floods. The mentioned factors have an impact on water resources i.e. groundwater level changes, water retention. The aim of the research was to assess the potential of small water reservoirs? automated monitoring, using Copernicus Sentinel-2 data. The study area is located in the Zachodniopomorskie Voivodeship in the north-western part of Poland. A set of different spectral indices: Normalized Difference Water Index (NDWI), Modified Normalized Difference Water Index (MNDWI) and Sentinel Water Mask (SWM) was examined and an algorithm of small water bodies detection was proposed. Overall Accuracy of the developed algorithm is 98-99%. The results of an automatic detection were also compared with the Polish National Database of Topographic Objects (BDOT10k). The results of the conducted analysis show huge discrepancies between the two mentioned sources of information and that the number and spatial extent of the examined water bodies has been changing in the recent years. Moreover, the conducted research indicates that Sentinel-2 satellite imagery have a potential to be used successfully in the small water reservoirs? monitoring.
