The condition of Lake Mornos shows signs of improvement after recent rainfall; however, it still remains below its normal size. Monitoring the status of this artificial lake is a priority for the METEO unit of the National Observatory of Athens, which employs satellite measurements, meteorological station data, and snow cover estimates to assess levels and changes.

Using high-resolution satellite data from Sentinel-2, the METEO unit reports that as of February 21, 2026, the area of Lake Mornos stands at 13 km². This is significantly lower – approximately 26% – than the average size of 17.6 km² for February from 2006 to 2024. Despite the recovery associated with abundant rainfall in Greece and the Mornos region, the lake's size continues to reflect persistent low conditions, raising concerns among experts regarding water resource management in the region.

The ongoing monitoring of Lake Mornos is crucial for understanding broader environmental trends and the potential impacts on local ecosystems and communities, particularly in a context where water scarcity can affect agriculture and drinking water supplies. The findings emphasize the importance of continued scientific observation and analysis to support effective resource management and decision-making for the lake's future.
