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.
