The case of the lagoon Kalochori is unique in Greece, as it is a "new" wetland created gradually from the mid-'50s, as a result of ground subsidence caused by overexploitation of water from underground aquifers in conjunction with the loose of the soil (Anastasiadis et al 2004).


Today the lagoon covers an area of 2,260 acres. The depth of the lagoon is 0.5 to 1 meter below the sea. Despite the general deterioration of the lagoon, due to drought, rubbish and waste, is one of the most important areas within the protected area because of the large number waders and water birds gathering here all year long.
