Kucukcece Lake is located west of Istanbul. The area is 16 square kilometers and the deepest point is about 20 meters. The important streams that feed the lake are Nakkas, Sazlı and Eskinoz. Unfortunately, these streams can no longer flow or carry only house and factory waste. Kucukcece Lake, which is the beach on the shores of the rivers when it flows cleanly, has now turned into a swamp in which creatures find it difficult to live because of the waste.
A few million years ago, the lake was a fertile plain with fi l, tigers, hyenas, deer and many other vertebrates. During this period, the lake was part of the Sea of Marmara. Over time, it became a lake, breaking away from the sea with sand sets piling up on the shore. After the Sazlıdere Dam is built, the lake loses its most important feeding source and becomes a swamp with each passing day.
Despite these setbacks, Small Drawer Lake continues to be an important resting place for migratory birds. Today, around 140 bird species are observed in the lake at certain times of the year. In the winter months, the endangered steep tails are wintering. Small Drawer Lake is also the breeding ground for long legs and thatche insanity. The nearly fourkm coastline, including the coast of the Nuclear Research Centre, shows many bird species, including cormorants, herons and wild ducks.
Located 1.5 kilometers north of The Small Drawer Lake, The Halfburgaz Cave bears the traces of people who lived in the region tens of thousands of years ago. There are also ruins of bathonea and the ancient city of Region around the lake.
