DS1: Trichonis Lake (Greece)
Trichonis Lake is the largest lake in Greece, spanning an area of 95.8 km², with a maximum length of 21.5 km, a maximum depth of 58 m, and a surface elevation of 15 m. The water temperature ranges from 4° to 25°C. The lake is known for its rich biodiversity and diverse wildlife, including endemic species of algae, birds, and fish. Human activities have significantly degraded large portions of the shoreline habitats. Additional pressures include chemical pollution, partly from agricultural sources such as waste from olive oil mills, water abstraction, climate change, and biodiversity loss.

DS2: Brates Lake (Romania)
Currently, Brateș Lake is significantly impacted by anthropogenic pollution. It has an average water depth of approximately 1-1.2 meters and suffers from nutrient enrichment, pollution from pesticides, heavy metals, and potential emerging pollutants. The lake also experiences large amounts of sediment accumulation brought in by tributaries, affecting water quality.
DS3: Langvatnet lake (Norway)
Langvatnet Lake is situated in Fauske Municipality in Nordland County, northern Norway. It measures approximately 10.7 km in length and 0.9 km in width, extending in a northwest-southeast direction, and covers an area of 5.63 km².
MS1: Vransko Lake (Croatia)
Vransko Lake is the largest lake in Croatia, measuring 13.6 km in length and between 1.4 and 3.4 km in width, with a surface area ranging from 29.8 to 30.02 km². It is separated from the sea by a strip of land that is 800 to 2,500 meters wide. The lake's average water level is approximately 83 cm, reaching up to 2.20 m during the winter. The water in the lake is consistently brackish, with salinity levels between 0.16 and 0.86 ‰.
MS2: Medard Lake (Czech Republic)
Medard Lake, located in the western part of the Czech Republic, covers an area of 490 hectares and has a maximum depth of 50 meters. It serves as a unique long-term ecological research area (LTER) for studying ecological processes in large, restored lentic ecosystems. The ongoing research focuses on the effects of intra- and interspecific interactions on fish community succession, the impacts of anthropogenic activities and long-term changes on water quality, the influence of submerged macrophytes on trophic relationships and fish distribution in deep lakes, and the composition of periphyton as well as the structure and biomass of phytoplankton.
MS3 : Zaghen Lake (Romania)
Zaghen Lake is situated in the Zaghen polder, covering an area of 180 hectares and holding a volume of 937,000 cubic meters. The lake is currently undergoing ecological restoration on 200 hectares of its surface, located on the lower Danube at the confluence with the Danube Delta.
