Agricultural, industrial, and human activities in general threaten water quality, as well as the biotic integrity of aquatic ecosystems. The increased concentration of total nitrogen (TN) and phosphorus (TP) affects high concentrations of chlorophyll (Chl-a) in freshwater ecosystems, which causes the process of eutrophication of the waters of shallow lakes. Eutrophication, as an alarming threat to the global quality of surface waters, affects environmental degradation. This research assesses the risk of eutrophication caused by chemical oxygen demand (COD), TN, TP, Secchi disk (SD), and Chl-a using the trophic level index (TLI) in Palic and Ludas lakes. Both lakes have been nominated as potential Natura 2000 areas in 2021 because they belong to important bird areas, and Ludas Lake has the status of Ramsar site 3YU002. In the research period from 2011 to 2021, the results showed that the lake is in an extremely eutrophic state. Laboratory analyses indicate an increased concentration of Chl-a during autumn. In the paper, the normalized difference chlorophyll index (NDCI) was calculated using the Google Earth Engine platform, and the result indicates the loading of the lake throughout the year, with an emphasis on winter, summer, and autumn. By using satellite images and remote sensing, it is possible to determine the most degraded spots, which is a help to the researchers in choosing the places where the samples will be taken and thus act more efficiently on the most endangered parts, as well as reduce the costs of standard in situ methods.
