The streams flowing from the Yıldız Mountains to the Black Sea along the Black Sea coast end in the lakes and the marshy areas of İğneada before reaching the sea. Lagoon lakes, which vary in size between Longoz forests and dunes, and forest inland lakes in the interior form the wetlands of the region. There are 5 lakes with rich aquatic vegetation in the area: Erikli Lake is a lagoon that is disconnected from the sea in summer. Mert Lake was formed at the place where Çavuşdere poured into the sea. Saka Lake, which is located in the south of the area, is a small lake of 50 da between forests and sand dunes. Hamam Lake and Pedina Lake are inside. The disconnection of Erikli Mert and Saka Lakes due to the dune barrier in front of the sea leads to the overflow of excess water in the spring and covering the flat land. These floodplains form flooded forests and different marine, lake and forest ecosystems. While the salt ratios of lagoon lakes change in rainy periods, their waters are bitter-salty. A reed and marshy belt surrounds the lagoon areas. Igneada physically divides the coastal dunes within the area. The coastal dunes located in the north start from the eastern part of Erikli Lake and extend to İğneada. The coastal dunes located in the south, starting from the canal region connecting Mert Lake to the sea, extend to the south of Lake Saka and its width reaches 50-60 meters. The dunes, which are approximately 10 kilometers long, are of great importance with plant species specific to the southwest of the Black Sea. Capable of hosting almost all beauties that one may want to see as a natural beauty throughout his life; İğneada, which is a natural wonder with its sea, fine sand beach, vast forest, lakes, streams and fresh air, is almost like a reflection of heaven.</d
